NORTHBOUND - Weekend of September 22
SOUTHBOUND - Weekend of October 20
Caltrans is scheduled to close Northbound and Southbound SR-87 on two weekends between late September 2023 and mid-October 2023. During the 56-hour highway closures, Caltrans will perform major pavement repair work on northbound and southbound SR-87 in Santa Clara County. One traffic direction on SR-87 will be worked on at a time. Detours will be in effect. All work is weather and conditions dependent.
CLOSURE WILL START FRIDAYS AFTER 9 P.M. AND CONCLUDE ON THE FOLLOWING MONDAYS NO LATER THAN 5 A.M.
These closures will allow for concrete pavement in traffic lanes to be replaced. These closures will shorten the duration of the project by providing improved safety and better ride quality to the public. These series of weekend SR-87 closures will reduce the number of overnight lane closures needed to complete this work by 2024 instead of completing in late 2025.
Northbound Detour A
Take southbound SR-85 to northbound US-101 to northbound I-280
Northbound Detour B
Take northbound SR-85 to northbound SR-17 to southbound I-280
Southbound Detour A
Take southbound I-280 to southbound US-101 to northbound SR-85
Southbound Detour B
Take northbound I-280 to southbound SR-17 to southbound SR-85
Why is the Work Needed?
The purpose of the project is to improve ride quality, enhance safety, and extend the service life of the pavement. These full weekend closures are necessary for worker and public safety during the work. Caltrans will perform major pavement rehabilitation on the two center traffic lanes in both the northbound and southbound directions of SR-87. The roadway has become worn and in need of major repairs due to decades of high traffic use.
The roadway pavement will be replaced with 20-year life cycle flexible pavement structure by cold planning and replacing the pavement to maintain existing profile grade. Upgrade 28 curb ramps at six intersections, resurface 2.9 miles of class I bikeway that runs parallel to the mainline, repair localized depressions in the roadway profile grade by injecting expanded polyurethane materials, replace the existing nonstandard median concrete barrier, replace asphalt concrete dikes, replace nonstandard guardrails, Place enhanced wet/night visibility striping and shoulder rumble strips, upgrade/replace drainage facilities and upgrade/replace various electrical systems, including traffic signals, traffic loop detectors, push buttons and pedestrian crossing signals.
