Traffic Switch at I-80 Gilman Street Interchange in Berkeley August 5, 2024

Published: Jul 31, 2024

BERKELEY / ALAMEDA COUNTY ― Caltrans has scheduled a traffic switch which will go into effect at the Interstate 80 Gilman Street interchange in Berkeley starting at 9:00 PM August 5, 2024. Motorists should drive with extra caution in the construction zone as the traffic lanes will be placed in a new configuration.

Westbound Gilman Street will be closed between Second Street and Eastshore Highway. Traffic on Eastbound West Frontage Road can only turn right at the new east roundabout. The temporary roundabout currently in place on the east side will remain and a new temporary roundabout on the west side will be added. See map below.

DETOURS:

For westbound Gilman at 2^nd Street: 1) Make a right at 2^nd Street. 2) Make a left at Harrison Street 3) Make a left at Eastshore Highway. 4) Make a right at Gilman.

For East Bound West Frontage Road heading to Tom Bates Sports Complex: 1) From West Frontage Road, make a slight right into the roundabout. 2) Go under the bridge. 3) At the east roundabout, loop around to go westbound (under the bridge). At west roundabout, take the roundabout exit toward Tom Bates/Golden Gate Fields.

The Gilman Street pedestrian overcrossing, which opened to the public in May, will remain open and all other elements of the interchange will be unchanged. The temporary roundabout on Gilman Street west of the Second Street intersection will remain in place.

Caltrans thanks pedestrians, cyclists, and motorists for your patience as we work to improve the Gilman Street intersection. Every effort will be made to minimize inconvenience to the traveling public.

Proper signs and pavement delineation, as well as portable changeable message signs, will be installed to guide cyclists, pedestrians and motorists.

Pedestrians will not be allowed to cross under the I-80 bridge during this phase of construction; they should use the newly opened pedestrian overcrossing on the south side of the interchange.

While the overcrossing will be open to the public, pedestrians, cyclists and anyone using the roundabout should use caution, as it is in an active construction zone. All traffic approaching the roundabout is required to yield to the traffic already in the roundabout.
