After four years and $100 million, Gilman Street interchange at Interstate 80 is open

BERKELEY — The Gilman Street interchange project had been in development for several years prior to its groundbreaking in May 2021. After four years of construction, which caused temporary closures and detours, a ribbon cutting ceremony was held Monday to mark the official opening of the new interchange that gives motorists, bicyclists and pedestrians access to a safer, less chaotic intersection at Gilman Street at the Eastshore Freeway in Berkeley near the Albany border. The project includes two roundabouts, bicycle and pedestrian paths and road improvements, opening up a clear and safe passage to the Bay Trail and waterfront.

The $100 million effort was a collaboration between Caltrans, the Alameda County Transportation Commission, and the cities of Berkeley and Albany, according to a press release. Funding for the project came from the State Transportation Improvement Program, voter-approved Measure BB funds and local and regional partners such as the city of Berkeley, East Bay MUD and the Bay Area Air District.A drone view of the Gilman Street interchange along Interstate 80 in Berkeley, Calif.
