For the second time this year, the Dumbarton Bridge will be closed during a holiday weekend.
The 1.6-mile bridge that connects Fremont to Menlo Park will be closed from 10 p.m. on Friday, Aug. 31 to 5 a.m. on Tuesday, Sept. 4.
According to dumbartonbridgeinfo.org, the three-day full closure of the bridge is needed so that crews can replace a portion of the eastern side of the bridge with “a state-of-the-art seismic joint,” which would make it more flexible during an earthquake.
The bridgework is part of the Dumbarton Bridge Seismic Retrofit, which is a portion of the San Francisco Bay Area Toll Bridge Seismic Retrofit Program. The project is expected to be completed by 2013.
Motorists can either go north and to use the San Mateo Bridge or south on Interstate 880 to Route 237 to reach Interstate 101 during the bridge closure.
During , crews replaced a western portion of the bridge with a new seismic joint.
