Clement Avenue/Tilden Way


Announcement: In May 2022, City staff asked community members to participate in the first round of stakeholder engagement for the Clement Avenue/Tilden Way Improvement Project - please see workshop materials from May 18: presentation(PDF, 10MB) - notes(PDF, 112KB) - video - outreach summary(PDF, 729KB).  The second round of outreach is expected in October 2022 with another online survey, virtual workshop and in-person open house.

The Clement Avenue Extension/Tilden Way project uses the abandoned railroad right-of-way along the eastern terminus of Clement Avenue and Tilden Way to extend the Cross Alameda Trail between Broadway and the Miller-Sweeney/Fruitvale Rail Bridges.  The project also will consider ways to improve the truck and bus routes in this area.  This project connects directly to the City's Clement Avenue Complete Street project, and to the City of Oakland's planned and funded Fruitvale Avenue improvements.  In 2017, the Alameda County Transportation Commission awarded a grant to the City of Alameda for $8.4 million to implement this project. This project is funded by Measure BB, Alameda County's transportation sales tax.

Project Goals

For the Clement Avenue/Tilden Way Project, the City seeks to:

  • Promote safety by prioritizing Vision Zero
  • Improve mobility for all modes, including AC Transit buses and trucks
  • Comply with City plans & policies
  • Provide flood reduction and landscaping opportunities
  • Reduce greenhouse gas emissions


The City staff/consultant team will consider various countermeasures to improve safety and operations such as road diets and roundabouts as described more below.

Road Diets

The reduction of motor vehicle travel lane(s) provides an opportunity to reallocate space for other uses such as bike lanes and a center two-way left-turn lane.  According to the Federal Highway Administration's informational guide(PDF, 2MB) , streets with travel lane reductions have multiple benefits for people driving, walking and bicycling, such as:
  • Decreases vehicle travel lanes for pedestrians to cross;
  • Allows for better visibility of pedestrians waiting or attempting to cross the street;
  • Improves circulation for bicyclists when a bikeway is added;
  • Reduces rear-end, sideswipe and left-turn collisions by at least 19 percent and up to 47 percent through the use of a center two-way left-turn lane;
  • Improves speed limit compliance by three to five miles per hour, which reduces the severity of collisions; and
  • Improves travel flow since through vehicles are separated from left turning vehicles.

The Federal Highway Administration (FHWA) has a case studies document and additional resources.  FHWA Video and Fact Sheets are as follows:


Roundabouts reduce the types of crashes where people are seriously hurt or killed by up to 90 percent when compared to conventional stop-controlled and signalized intersections.  Roundabouts result in lower vehicle speeds around the roundabout.  Crashes that occur will be less severe because of this reduced speed and the more “sideswipe” nature of crashes.  Pedestrians are generally safer at roundabouts, and are faced with simpler decisions at a time. Videos and presentations on roundabouts are as follows:
