To prepare for the replacement of bridges over San Francisquito Creek, lanes along U.S. Highway 101 in Palo Alto will be closed overnight this weekend, the California Department of Transportation (Caltrans) has announced.
Multiple northbound lanes will be closed between Embarcadero Road and University Avenue starting on Friday at 9 p.m. and extending until Saturday at 8 a.m. to ensure the safety of work crews, Caltrans stated.
Multiple southbound lanes will be closed between University and Embarcadero starting Saturday at 10 p.m. and lasting until Sunday at 9 a.m.
Traffic will be shifted towards the outside shoulders in both the northbound and southbound directions, with the auxiliary lanes temporarily removed.
The $18 million bridge project, which has a completion deadline of 2017, will remove and replace the Highway 101 bridge over the San Francisquito Creek at the border of San Mateo County and Santa Clara County. The project will also remove and replace the West Bayshore Road and East Bayshore Road bridges over the creek, according to Caltrans.
The work is being done to prevent predicted flooding of neighborhoods along the San Francisquito Creek.
The Highway 101 bridge was constructed in 1931 and widened in 1957 to include the frontage roads on either side of the freeway. Over the years, the bridge has deteriorated from wear and tidal action, Caltrans' website states.
Due to a history of flooding in this area, the San Francisquito Creek Joint Powers Authority (SFCJPA) has proposed improvements to the creek, including new bridges, to increase the hydraulic capacity both upstream and downstream.
The new bridges will have lower maintenance cost and provide protection from flooding, Caltrans states.
The state agency is working on the project with the creek authority, whose members include the cities of Palo Alto, Menlo Park and East Palo Alto, the Santa Clara Valley Water District and the San Mateo County Flood Control District.
Construction is expected to occur over three seasons with most of the work taking place from June to October.
Real-time traffic conditions and road closures can be viewed on the Caltrans Quick Map.
