MaineDOT’s Three-Year Work Plan

2025 Edition

Overview

Introduction

This Work Plan describes all work planned by MaineDOT and its transportation partners for calendar years 2025, 2026, and 2027. It includes 2,716 individual work items with a total value of $4.8 billion. 

This Work Plan includes all capital projects and programs, maintenance and operations activities, planning initiatives, and administrative functions for three calendar years. It consists principally of work to be delivered or coordinated through MaineDOT. It also includes funds to be expended by other transportation partners, including airports and transit agencies, that receive federal funds directly.

Every project in this Work Plan helps MaineDOT fulfill its mission:  “to support economic opportunity and quality of life by responsibly providing our customers the safest and most reliable transportation system possible, given available resources.”

This story map provides a high-level overview of our work areas and goals. We invite you to check out what we have planned for your area and for the entire state in the years to come.

State of the System

Transportation will always be a big job in Maine. The enormity of our transportation system, our relatively small population, and the natural features of our state create significant challenges when it comes to managing our infrastructure assets.

The process of creating MaineDOT’s Work Plan is ongoing and always evolving. As we approach the end of each calendar year and prepare for the release of the next Work Plan, we compile a fact-based assessment of our asset conditions and performance levels. We have begun to refer to this assessment as our State of the System report. This report combines various asset management data in one place, reviews progress since our last Work Plan release, and generally describes the impacts of varying funding levels moving forward.

This year’s State of the System report identifies additional investments needed in areas that include:

  • Bridges, minor spans, and large culverts – Recent asset condition assessments confirm a troubling trend of an increasing percentage of poor structures in this category. In the case of the percentage of bridges rated in poor condition, Maine trails other states both in New England and around the rest of the nation.
  • Interstate rutting – Maine’s interstate system is in very good condition except for premature rutting. MaineDOT’s engineers have begun an extensive study to determine the causes of this rutting.
  • Rural transit vehicles – Maine’s rural transit vehicle fleet is old. Our state’s entire rural transit fleet is at 116 percent of its projected useful life.

In future years, MaineDOT plans to compile subsequent State of the System reports in the fall, closer to the beginning of the creation of the next edition of the Work Plan.

Funding

Maine’s transportation needs continue to outpace available resources. This has been the case for decades. In recent years, inflationary pressures have further complicated the matter. From the beginning of 2019 to the beginning of 2024, the National Highway Construction Cost Index shows a 71-percent increase in construction costs.

Fortunately for the people of Maine, lawmakers at both the federal and state levels have stepped up in recent years, working in a bipartisan fashion to deliver for transportation. This critical support has helped MaineDOT continue to deliver on its mission. The 2021 Bipartisan Infrastructure Law has been a game-changer for transportation funding in Maine. Additional support provided by the Mills Administration and the Maine Legislature has allowed the team at MaineDOT to start making real progress for the people of our state.

Creating MaineDOT’s Work Plan requires that we estimate future funding levels using reasonable assumptions. We make these assumptions with humility and respect, noting that decisions regarding funding are ultimately made by policymakers.

As mentioned above, MaineDOT’s State of the System report generally describes the impacts of varying funding levels moving forward. These are the three funding levels we have evaluated for this edition of the Work Plan:

  • MacGyver Mode – A return to lower transportation investments would require MaineDOT to go back to competently managing the slow decline of the transportation system. This level of investment would allow our team to operate and maintain the system in an acceptable way, but asset performance levels would likely decline. While dollar-stretching ingenuity will always be part of managing a transportation system like ours, it can’t be the only approach if we want to continue to make progress.
  • Pragmatic Progress – This level of investment would keep MaineDOT on its current track, allowing Maine to make steady progress in targeted areas. Performance measures in all modes would be maintained or improved with reasoned levels of investment. This funding level would support strategic investments in villages, limited capacity expansion, targeted multimodal improvements, highway improvement programs, and bridge investments for a sustainable transportation system.
  • Aspirational – This level of investment would address all identified needs and raise performance levels. It would reflect responsible progress at accelerated rates. Aspirational levels of investment would result in conditions improving to meet or exceed State of Good Repair levels. This would not be an unlimited funding level but a level that is supported through quantifiable calculations with associated expected performance.

This Work Plan assumes that current funding levels will remain, providing MaineDOT with the resources needed to continue on a path of pragmatic progress. This approach reflects recent bipartisan judgements and provides enhanced safety, economic prosperity, and quality of life benefits in a measured and sustainable way.

This Work Plan contains more than $1 billion in funding from federal discretionary grant programs and Congressionally Directed Spending awards. Many of the major projects planned for the years ahead involve these special funding sources and are detailed below.

In 2024, MaineDOT received 14 discretionary grant awards through the Bipartisan Infrastructure Law. These awards total more than $309 million and will be used to support projects with a total cost of almost $400 million.

Planning

Underlying Principles and Approach

MaineDOT published its Family of Plans in 2023. These plans play an important role in providing short and long-term strategic direction and the policy objectives and performance measure targets for the system. These policy objectives and performance targets are critical in determining investments strategies and levels when evaluated against current asset condition and performance. The Family of Plans include the Long-Range Transportation Plan, Maine State Active Transportation Plan, Maine State Transit Plan, Maine State Aviation System Plan, Maine State Rail Plan, and the Maine Integrated Freight Strategy.

Partnerships

MaineDOT currently has five community-based initiatives and is launching a sixth with this Work Plan. While each one serves a unique purpose, these programs are all designed to identify specific transportation system improvements that can help communities better realize their own visions and priorities.

  • Village Partnership Initiative (VPI) – Launched in 2022, MaineDOT’s VPI focuses on projects in lower-speed areas where people meet, walk, shop, and do business on a human scale. Maine's iconic New England villages are part of who we are, part of our brand, and a key part of our economy and quality of life. Simply put, the goal of the VPI is to make sure that once you get there, the there is a place you want to be. In this way, these projects can be bigger than transportation; they can become placemaking.

VPI projects are already underway in Sanford, Windham, and Portland. These projects have already been awarded discretionary federal grant funding. Several other projects are also moving forward into the preliminary engineering and design phases.

MaineDOT continues to work with dozens of additional studies that may result in future VPI projects.

  • Planning Partnership Initiative (PPI) – The PPI is intended to address time-sensitive, locally initiated planning and feasibility studies that occur outside MaineDOT’s normal annual Work Plan cycle. This program is intended to be simple, flexible, and fast-moving for new economic development and other high-priority proposals. PPI work may result in a VPI.

The map below highlights both Planning Partnership Initiative and Village Partnership Initiative projects included in this Work Plan.

  • Municipal Partnership Initiative (MPI) – MaineDOT’s MPI is intended to be a streamlined program to address municipal requests that deal with transportation infrastructure issues on state and state-aid highways, encourage economic opportunities, and make improvements to infrastructure to increase its life or correct safety deficiencies.
  • Urban Partnership Initiative (UPI) - Starting in 2025 and available to municipalities within Maine's four Metropolitan Planning Organizations (MPOs), this program is intended to target improvements to active transportation. Examples of improvements include new sidewalk construction, sidewalk reconstruction, multi-use trail connectivity to highways, accessibility upgrades to existing facilities, and intersection safety improvements.
  • Business Partnership Initiative (BPI) – The BPI is designed to promote public/private partnerships between MaineDOT and municipalities, public utilities, private businesses, and other entities by leveraging additional resources on a voluntary basis to match limited state resources.

With the publication of this Work Plan MaineDOT is establishing a new partnership initiative:  the Active Transportation Partnership Initiative (ATPI). This new initiative is designed to help communities access funding to enhance active transportation infrastructure and safety for vulnerable road users. 

Highways & Bridges

Maine has approximately 8,800 miles of state-jurisdiction highways and a little bit more than 2,800 state-jurisdiction bridges and minor spans. This network is the largest and most heavily used component of Maine’s transportation system; it represents nearly 40 percent of all road miles in Maine but carries almost 90 percent of the total vehicle-miles traveled in our state.

This Work Plan invests more than $2.7 billion in these highways and bridges. Most of that amount is for capital investments. Those investments include:

  • 242 bridge construction and 95 bridge engineering projects – $998 million.
  • 157 miles of highway construction and rehabilitation – $667 million.
  • 255 highway safety and spot improvements – $216 million.
  • 1,210 miles of preservation paving – $632 million.
  • 2,100 miles of Light Capital Paving (LCP) – $120 million.

The ongoing maintenance of Maine’s highway and bridge system is essential to the movement of people and goods and to the health of our state’s economy. Actual expenditures for this work vary from year to year depending on the constantly changing condition of the transportation system and, importantly, the weather. Highway and bridge maintenance and operations work accounts for $669 million in this Work Plan. Three-year annual averages for major maintenance and operations work include:

  • Winter maintenance - $51.0 million.
  • Drainage maintenance - $28.6 million.
  • Custodial maintenance - $19.1 million.
  • Bridge and other infrastructure inspections - $14.8 million.
  • Surface and base maintenance - $12 million.
  • Bridge and structural maintenance - $12.2 million.
  • Operational and safety maintenance – $7 million.

Climate Initiatives

Carbon Reduction Strategy

MaineDOT’s  Carbon Reduction Strategy (CRS)  serves as a guide for MaineDOT to reduce carbon emissions from our state’s transportation system. The CRS aligns with the state climate plan –  Maine Won’t Wait  – as well as with the visions and goals laid out in MaineDOT’s Family of Plans. MaineDOT will take data-driven and practical actions to both reduce emissions in the transportation sector and increase the resiliency of infrastructure across the state.

MaineDOT is investing in projects that will improve active transportation and transit options. Programmed funds in this Work Plan include:

  • Construction of extensions of the Eastern Trail, Beth Condon Trail, and the Mountain Division Trail, for a total of more than 12 miles of new trail.
  • Design for an additional 12 miles of the Eastern Trail and Mountain Division Trail extensions.
  • Support for the establishment of a bikeshare system in greater Bangor.
  • Design funds to support Phase III of Greater Portland Metro’s Transit Stop Access Project.
  • Updated equipment for the York County Community Action Corporation’s bus fleet to improve the transit user experience.

Infrastructure Resiliency

MaineDOT administers the Maine Infrastructure Adaptation Fund (MIAF) and the Municipal Stream Crossing (MSC) Program. These programs aim to make targeted investments that increase the resiliency of our state’s infrastructure.

The MIAF provides direct funding to public entities to upgrade their critical infrastructure to reduce vulnerability to extreme weather, sea level rise, inland and coastal flooding, and other impacts. MaineDOT has held three rounds of funding through the MIAF. The first round, in 2022, provided $20 million to 12 communities. The second round, at the beginning of 2024, provided $1.3 million to 19 communities. The third round, in August 2024, provided $25.2 million in grants funds to 39 communities.

The MSC program funds the upgrade of municipal culverts with the goal of providing safe stream crossings while accommodating natural resources. MaineDOT held one round of funding through the MSC Program and provided $4 million in grants to 18 communities in 2024.

Electric Vehicle Infrastructure

MaineDOT has been working with Efficiency Maine Trust (EMT) to expand electric vehicle charging infrastructure across the state. Through Recharge Maine – the state’s initiative to create a convenient, reliable, and accessible EV charging network across Maine – the state is investing $52 million in state and federal funding to install more than 700 charging ports statewide.

  • Between 2018 and 2024, MaineDOT and EMT awarded more than $17 million in funds to install more than 130 Level 3 fast-charger ports and more than 350 Level 2 charger ports across the state.
  • The Maine State Ferry Service’s first hybrid-assist ferry, the Captain Almer Dinsmore, is scheduled to arrive in Maine in 2025. The department is committed to considering hybrid ferry options for all future ferry replacements.

Active Transportation

Active transportation (walking, bicycling, or other mobility based around human physical activity) accounts for the second most widely used form of transportation in Maine (behind motor vehicles). This Work Plan includes $95 million in stand-alone investments for active transportation. This is in addition to other projects funded as part of larger highway and bridge projects that also integrate active transportation improvements. These investments help reduce carbon emissions by offering alternatives to driving. The stand-alone projects in this Work Plan include:

  • Design and construction of 10 miles of off-road trail on the Mountain Division Rail Line from Fryeburg to Hiram – $11 million.
  • Investments in vulnerable road user safety through new partnerships with municipalities through a new Active Transportation Partnership Initiative – $3.1 million.
  • Construction of a phase of the Union Branch Pathway in Portland from Park Avenue to Forest Avenue – $3.1 million.
  • Construction of a multiuse path in Damariscotta to connect commercial areas and a school – $1.7 million.

Aviation

Maine has six commercial airports and 29 general aviation airports. This Work Plan provides $170 million in funding for the state aviation system. This includes $164 million for capital projects and $6 million for operations at Maine’s state-owned airports. These aviation investments include:

  • Facility rehabilitation and construction – $20 million.
  • Rehabilitation, reconstruction, and maintenance for runways, aprons, and taxiways – $7.8 million.
  • Upgraded airfield lighting, obstruction clearing, and snow removal equipment – $3.3 million.
  • Five automated weather observation systems – $3 million.

Additionally, this Work Plan includes measures that will improve energy efficiency and sustainability at Maine’s airports. This includes building infrastructure to support next generation aviation operations, the installation of airside EV charging stations, and the introduction of electric-powered ground support equipment.

Transit

This Work Plan provides $289 million in transit investments across the state. This includes $130 million in capital projects and $159 million to support transit operations. These investments provide critical support to Maine’s 22 regional and local transit providers. The annual state subsidy for statewide transit operations is $5 million.

Other transit investments include:

  • Federal RAISE Grant to purchase electric buses and charging infrastructure for Downeast Transportation to provide services to Acadia National Park and surrounding areas – $29.4 million.
  • Rehabilitation work on the City of Bangor’s Community Connector bus storage facility, including work to help prepare the facility for the future installation of electric vehicle charging equipment – $9.8 million.
  • Federal Transit Administration grant to renovate aging transit facilities and replace diesel buses – $3.8 million.
  • Support for the GO Maine ridesharing program, in partnership with the Maine Turnpike Authority – $1.5 million.
  • Ongoing operations of a two-year operating pilot bus service between Portland and Lewiston/Auburn launched in 2024 to support commuters and workforce development efforts – $1.3 million annually.

Ferry Service

The ferry services that serve Maine’s island communities are critical connections between those communities and the mainland. This Work Plan provides $105 million in support of ferry projects. This includes nearly $50 million for capital projects and $55 million for ongoing operations. These projects include:

  • The design and construction of shoreside improvements at Lincolnville and Isleboro to accommodate a larger, hybrid ferry – $33 million.
  • Electrical upgrades on the Swan’s Island and Bass Harbor transfer bridges – $3.2 million.
  • Parking lot and sidewalk improvements on Vinalhaven – $1.8 million.
  • Painting the Peaks Island Transfer Bridge – $1 million.

This Work Plan includes three years of the cost of ongoing operations of the Maine State Ferry Service. Farebox prices are adjusted periodically to cover half of the operating costs, while the other half, or about $8.5 million per year, is an ongoing state subsidy.

Passenger Rail

This Work Plan provides $94 million in federal, state, and farebox resources to support Amtrack Downeaster operations over three years. This service helps provide greater connectivity between Midcoast Maine and the Greater Boston area. The Downeaster ridership has returned to pre-pandemic levels and is now serving nearly 600,000 passengers a year.

Freight Rail

Every year, more than one million tons of freight move over state-owned rail lines. That’s the equivalent of 63,000 trucks. The freight rail network provides critical infrastructure that supports the movement of goods and materials, and this helps strengthen our state’s economy.

This Work Plan provides $181 million for capital freight projects. These include:

  • Improvements to the Brownville-to-Millinocket and Brownville-to-Vanceboro rail lines, made possible through a Consolidated Rail Infrastructure and Safety Improvements (CRISI) Grant - $66.6 million.
  • Improvements to the Gray-to-Waterville CSX line, made possible through a CRISI Grant - $42.4 million.
  • Ongoing funding for the Industrial Rail Access Program (IRAP) program to support heavy rail cars and double-stack clearances – $17 million.
  • Rehabilitation of the rail bridge over the New Meadows River in West Bath – $4 million.

Ports & Marine

Maine has three deepwater ports. The working waterfronts along our state’s coastline rely on investments to critical infrastructure in ports and harbors. This Work Plan provides $88 million for capital projects to support the development of Maine’s ports and marine infrastructure. Highlights of that work include:

  • A Port Infrastructure Development Program (PDIP) Grant for a refrigeration infrastructure which, along with the new cold storage facility at the International Marine Terminal (IMT) in Portland, will double the current refrigerated storage capacity at the IMT – $17.8 million.
  • Small Harbor Improvement Plan (SHIP) projects – $12.3 million.
  • Boating Infrastructure Grants (BIG) from the U.S. Fish and Wildlife Service – $7.8 million.
