In Sept 2024, the U.S. Department of Transportation (USDOT) announced more than $1 billion in grants including $16 million to the City of Alameda for the Lincoln/Marshall/Pacific corridor improvement project. In the April 2023 City Council meeting, City Council endorsed the design concept of the Lincoln Avenue/Marshall Way/Pacific Avenue Corridor Improvement Project(PDF, 4MB)(PDF, 4MB) and approved the consultant contract to continue with design, which is in process and is expected to continue through 2026. Construction is anticipated to commence in 2027 and be completed in 2028.
Concept:
The concept includes a roundabout at Lincoln Avenue/Fifth Street/Marshall Way, flashing beacons, pedestrian/bicycle signals, modernized traffic signals, crosswalk improvements, school frontage safety and efficiency improvements with bus loading zones and bikeways, stormwater gardens and best practices, street trees, disabled parking and loading zones, improved lighting and bus stop efficiency enhancements. Public on-street parking will be maintained except adjacent to the roundabout and at intersections and select driveways to improve visibility. Because a roundabout is more efficient than a traffic signal, the proposed design will increase vehicle capacity at the Fifth Street/Lincoln Avenue intersection. The consultant findings confirm that a single-lane roundabout has greater motor vehicle capacity than the existing roadway configuration.
Background:
The City identified the Lincoln Avenue/Marshall Way/Pacific Avenue corridor between Alameda Point at Main Street/Central Avenue and Broadway as a high priority for safety and mobility improvements. The corridor connects neighborhoods across Alameda, is over three miles long, and serves multiple destinations including schools, commercial districts and parks. It is a Tier 1 high injury corridor with several high crash intersections according to the City's Vision Zero Action Plan. City staff/consultant team evaluated the corridor uses, intersection controls and crash data, and conducted two rounds of community outreach. Roundabouts reduce fatal and severe injury crashes up to 78 percent compared to traffic signals.
