Fremont Avenue Bridge Replacement

Project Category:
Streets and Roadways
Project Status: 
In Construction
Project Lead:

Year Adopted:
Target Completion Date:
Fremont Avenue Bridge Los Altos, CA 94024

The Fremont Avenue Bridge is located on Fremont Avenue between Hazelaar Way and Miramonte Avenue, spanning over the Permanente Creek. Fremont Avenue is a principle collector urban road in the City of Los Altos. The bridge was built in 1915 and carries two lanes of traffic, one in each direction. The total curb-to-curb width is approximately 24 feet and currently no shoulders are present on the bridge. A timber sidewalk was added to the exterior on the south side of the bridge that has been out-of-service for several years. There is a separate wood structure north of the bridge, which carries bicycles and pedestrian traffic over the creek.

The bridge was determined to be functionally obsolete during an inspection by the California Department of Transportation. The main deficiency is that the lane and shoulder widths are too narrow relative to current standards and the amount of traffic the bridge carries.

Major funding for this project is provided by the California Department of Transportation (CalTrans). The bridge replacement project began in July 2015 and will take approximately 180 working days to complete.

Preparation for work to begin was completed in 2014 and included canopy removal from two trees and a shrub tree, and installation of netting to prevent birds from nesting in the trees surrounding the bridge and in the bridge structure itself.

Anticipated Traffic Impacts

During construction, the Fremont Avenue Bridge will be closed with no through traffic allowed. Motorists traveling westbound on Fremont Avenue will use Grant Road as their detour route to either Foothill Expressway or Portland Avenue to access the west side of Fremont Avenue Bridge. Motorists traveling eastbound on Fremont Avenue will use Miramonte Avenue as their detour route to either Foothill Expressway or Portland Avenue to access the east side of Fremont Avenue Bridge.

Status Updates

July 15, 2015:
The City has received feedback from residents regarding the detour signs associated with the Fremont Avenue Bridge Replacement project and  would like to provide an update in response to resident concerns that have been expressed.

The City’s intention is to keep detour traffic on collector streets (Grant Road and Portland Avenue) and Foothill Expressway. Unfortunately, many drivers in the area are not yet accustomed to the bridge closure and are not following the detour signs that are placed far in advance of the closure. As a result, many drivers were continuing down Fremont Avenue, only to have to make a U-turn. The bridge project contractors saw this and placed an additional detour sign directing traffic down Oakhurst. This sign, while placed with good intentions, was not part of the approved traffic management plan and has since been removed.

Additional signage will be in place by the end of the week to help clarify to motorist travelling westbound on Fremont that they should take Grant Road to detour around the bridge closure. Additional signage will also be placed at Miramonte Avenue clarifying eastbound detour directions.  

Should you have any questions or concerns about this project, please do not hesitate to contact the City’s Engineering Division at (650) 947-2780. 

July 2, 2015:
Beginning Monday, July 6, 2015, crews will be placing construction signs, performing construction staking, and completing preparation work for the bridge demolition. Fremont Avenue Bridge will be closed to vehicular traffic beginning Monday, July 13, 2015. All construction signs and traffic control measures will be in place prior to the closure. The existing pedestrian bridge at the North of Fremont Avenue Bridge will remain open during the construction except for some events (i.e. demolition, pile drilling, placing girders, etc.). The City will provide as much advanced noticing of pedestrian bridge closures as possible.

May 28, 2015:
The Fremont Avenue Bridge Replacement Project bid was awarded to Granite Construction Company at the May 12, 2015 City Council meeting. The City is currently working with Granite Construction Co. on the project contract. Once the contract is approved, the City will issue a notice to proceed. This will give Granite Construction Co. the OK to move forward and begin construction. Once the notice to proceed has been issued, the 180 working days to complete the project will begin.

February 11, 2014:
In preparation for work tentatively scheduled to begin later this year on the Fremont Avenue Bridge Replacement Project, tree trimming and other site prep-work is scheduled to take place on Saturday, February 15, 2014.

The Fremont Avenue Bridge will be closed to vehicular traffic on Saturday, February 15 from 8:00 a.m. until 5:00 p.m. from Hazelaar Way to Miramonte Avenue. Traffic control measures, including light boards, will be in place beginning Wednesday, February 12 to alert drivers of the upcoming closure and to detour traffic around the closure. The current schedule is subject to change due to poor weather or other unforeseen conditions.
