City Eyes Converting Bay Farm Intersection to a Traffic Circle

Alameda city staff is inviting residents to a virtual workshop to discuss the Mecartney Road/Island Drive Improvement Project on Dec. 1 via Zoom.

The project aims to improve safety at the Bay Farm intersection. The city is considering four options: a roundabout, a reduced footprint all-way stop, a traffic signal or make no changes. Based on an analysis of the intersection, the safest options are the roundabout and the reduced footprint all-way stop.

City staff and consultants are expected to request approval of a Mecartney/Island Improvement Project concept by Wednesday, March 23, 2022, from the Transportation Commission and on Tuesday, May 3, 2022, from the City Council.

The city hired Kittelson & Associates, Inc., an engineering consultant firm, as advisors.

The Mecartney Road/Island Drive Improvement Project plan is one of many projects aimed at improving safety at crosswalks. Several initiatives in the city’s Draft 2040 General Plan places an emphasis on creating safer streets for commuters. Vision Zero is featured in the Draft 2040 General Plan. It aims to eliminate fatalities and severe injuries on Alameda’s streets, avenues, sidewalks, crosswalks, paths, and trails. Also, the Intersection Safety initiative proposes to improve safety at stop-controlled or signalized intersections, and consider a roundabout design. Lastly, Roundabouts and Traffic Circles are being advised by city leaders when considering modifications to an intersection.

According to reports, traffic collisions are down slightly in 2021 from 2019, but traffic fatalities figures remain the same. According to Alameda Police Department, there were 751 traffic collisions in 2019 compared to 357 collisions in 2021 as of July. There were 541 traffic crashes in 2020, but there were fewer vehicles on the road due to the COVID-19 pandemic.

Four people died in traffic crashes in Alameda this year, the same as last year, including Alameda County Supervisor Wilma Chan who was struck and killed on Nov. 3.

This planning effort is funded by Measures B and BB transportation sales tax, which are administered by the Alameda County Transportation Commission.
