Work is progressing on Foothill Expressway improvements in Los Altos, with the project expected to wrap up by the end of the year.
The Santa Clara County-led project involves widening of the expressway between the El Monte Avenue and San Antonio Road intersections.
Crews finished phase 1 of the $6.6 million project in mid-July. Work included digging potholes for underground utilities, removing existing roadway asphalt, removing existing curbs and gutters, grading and installing new sidewalks and signal pole foundations.
Phase 2 of the project, which began July 6, involved work at the northeast and southwest corners of Foothill Expressway and El Monte. Work covered demolition of concrete islands, roadway excavation, installation of new sidewalk and curbs, roadway paving and installation of signal pole foundations. Phase 2 was completed at the end of August.
The project is currently in phase 3, which includes installation of conduits, boxes and foundation at the San Antonio Road intersection; installation of a temporary signal at San Antonio; median island work (excavation, curb removal and installation of new curb and island); and grading and paving the median roadway.
According to senior civil engineer Roy Cabaltera, crews with contractor Redgwick Construction Co. encountered “minor” delays during phase 1 due to “conflict of underground utilities encountered during excavation.”
“The project got delayed due to an unmarked AT&T fiber optic that was hit by the project boring equipment,” he said. “ATT responded late in repairing their fiber optic. However, we are still pushing for a project completion by the end of the year, weather permitting.”
The improvement project along Foothill adds an additional lane in each direction. The intersection improvements at El Monte and San Antonio include the addition of a second through lane on westbound El Monte and a second right-turn lane from southbound Foothill onto westbound El Monte.
All four corners of the intersection will be squared to improve bicycle and pedestrian safety.
Other improvements include modification of traffic signals, pavement treatment and landscaping.
