Highway 1 Safety - South

5/3/2021 Project Update: 

Half Moon Bay’s Highway Safety and Operational Improvements South Project is underway. To ensure maximum public safety as the project continues, the City has been working closely with Caltrans (which oversees all construction within the State Highway system) on making improvements to the construction zone. 

As part of this process, Caltrans has approved modifications to the road closure and detour plans. As of December 17, 2020, Main Street at Highway 1 is closed to all through traffic. Over 50 detour signs have been posted in the areas leading up to the closure to mark the alternative routes to access Highway 1 and Main Street. This closure will be in effect for approximately six months.  

Project Description: This project will provide operational and safety improvements to Highway 1 between Wavecrest Road and Seymour Street. It includes construction of a new signalized intersection at S. Main Street and Highway 1, modify the right turn to S. Main Street from northbound Highway 1, add three protected pedestrian crossings across Highway 1/S. Main St and protected bike-box on S. Main Street.  The project also includes two curved concrete entry structures and landscape improvements to create the Southern Gateway to downtown.

Project Status:  The City Council has awarded the construction contract to Redgwick Construction Company.  Construction started in October 2020 and expected to complete in late 2021.

Funding Source(s): Measure A grant from San Mateo County Transportation Authority (SMCTA) and City General Funds.

Latest Update: 5/3/2021 -  The contractor has completed all underground utilities, installed the signals structures, the two large concrete entry signs and concrete sidewalks, curb and gutters.  Next expected work include paving and median improvements followed by landscaping.
