Charleston / Arastradero Corridor Project

Upcoming Work 

Middlefield Road Traffic Signal Cable Work
In continuation from the Middlefield switchover, the contractor will be working within the traffic signal cabinet at the intersection of Middlefield Road and E Charleston Road for cable work on March 30. Traffic delays are expected during construction hours from 9 a.m. to 4 p.m. 

Concrete Work at El Camino Real 
The contractor will be removing and replacing concrete sidewalks, curb ramps, curbs, and gutters starting at the southern intersection corners of El Camino Real and W Charleston/ Arastradero Road. Work is currently scheduled to start on March 30, weather permitting, and is estimated to be complete by the end of April.

Traffic Signage Installation
The contractor will resume installing a new traffic signal on Arastradero and Charleston roads the week of March 27, weather permitting. Work is estimated to take a couple of weeks to complete.

Concrete Patching Work
The contractor will be doing concrete patching at various locations throughout the corridor, where temporary asphalt was placed due to removing old signal pole foundations and irrigation crossing work. The contractor will be pouring concrete back at these locations following the completion of the El Camino Real concrete work. Work is estimated to start the week of April 24 and take a week to complete.

El Camino Real Landscape Planting
Following the completion of the concrete work, the contractor will be installing landscaping at the northeast and southeast intersection corners of El Camino Real and W Charleston/ Arastradero Road. Work is estimated to start at the end of April and take a week to complete.

Remaining Project Activities

Although the project is making steady progress, there are several outstanding construction activities that need to take place before completion, including:

• Improvements at the El Camino intersection, which includes paving and striping. 

• Signal activation at the Wilkie Way intersection.

The City will communicate schedule updates as dates for these activities get finalized -- pending the delivery of traffic signal equipment and coordination with other agencies.

  Roadway improvements have been constructed on Arastradero Road from Foothill Expressway to Clemo Avenue.  Improvements included are curb extensions, sidewalk expansions, enhanced bicycle lanes, a protected cycle track, traffic signal improvements, landscaped median islands, new lane configurations, and new street trees. Phase 1 was completed in November 2020.
