Adeline Quick Build

The Adeline Quick Build will use temporary materials to test street safety improvements on Adeline Street between Ashby Avenue and the Berkeley–Oakland border. These changes build on the community vision established in the 2020 Adeline Corridor Specific Plan and reflect what we’ve heard from residents: a desire for safer crossings, slower traffic, and a more welcoming street for everyone.

This project is part of a larger effort to improve safety under Berkeley’s Vision Zero program, which aims to eliminate severe traffic injuries and fatalities. It will also help close a major gap in the bicycle and pedestrian network along the Adeline/MLK corridor.

Project Context

The Adeline Quick Build, planned for 2027, will:

• Reduce the number of vehicle lanes
• Add concrete transit boarding islands
• Add pedestrian refuge islands
• Create a mix of Class IV separated bikeways (cycle tracks) and Class II bike lanes

This section of Adeline will extend from Ashby Avenue to 61st Street and remove one lane in each direction from Adeline & MLK Way to the City of Oakland border.

Regional Coordination

• North: The Adeline Street Improvements, completed in 2020, made similar changes from Shattuck Avenue to Ashby Avenue.
• South: The City of Oakland is implementing its Martin Luther King Jr Way Complete Streets Paving Project in 2026 from 47th Street to 61st Street, which will also reduce vehicle lanes, implement bike lanes, and add protected pedestrian crossings and bus boarding islands.

Together, the projects create a continuous 1.7-mile corridor that improves safety throughout Berkeley and Oakland.

The Adeline Quick Build will also serve as a pilot project to inform the long-term Adeline Transportation Improvements Project with before-and-after data collection on multimodal corridor use.
