Auxiliary lanes are short distance lanes located between entrance and exit ramps on the freeway designed to allow for speed change, weaving, and other safety and operational purposes supplementary to through-traffic movement. You can think of the as a transition zone for cars entering the freeway and merging into the travel lanes. 

This project is proposing the addition of two auxiliary lanes along the northbound corridor, and two auxiliary lanes along the southbound corridor. The proposed locations of auxiliary lanes are as follows:

Proposed Auxiliary Lanes on Northbound I-405 (2 Locations)

• Between the Wilmington Av northbound on-ramp and the Carson St northbound loop off-ramp 
• Between the Carson St northbound on-ramp and the Avalon Bl northbound off-ramp 

Proposed Auxiliary Lanes on Southbound I-405 (2 locations) 

• Between the Avalon Bl southbound on-ramp and the Carson St southbound loop off-ramp 
• Between the Carson St southbound on-ramp and the Wilmington Av southbound off-ramp 

Complete Streets elements, which are proposed in both  Alternatives 2 & 3 , are an approach to enhance mobility, accessibility, and connectivity along the existing corridor. Complete Streets would promote multi-modal travel options for all users, including pedestrians, bicyclists, motorists, and transit riders. Examples of Complete Streets elements that are proposed as part of this project include the following:  

• ADA compliant sidewalks and curb ramps 
• Additional bicycle facilities 
• Improved lighting under bridges for pedestrian and bicycle crossings 
• Safer crosswalks 
• Accommodation of future transit and multi-modal connections 

Transportation Systems Management (TSM) and Transportation Demand Management (TDM) strategies include elements to improve traffic management. These may include CCTV systems to monitor traffic movement, ramp metering and vehicle detection systems, street signal synchronization, turn lane additions, changeable message signs, and more. These elements preserve access to bike lanes and trails. TSM/TDM strategies are folded into all build alternatives, where applicable.
