State Route 87 Roadway Rehabilitation

Overnight Lane Closures on State Route 87 for Pavement Improvement Project Between Julian Street and State Route 85

Closures will continue from March 12, 2024, until the completion of the project.

San Jose – The California Department of Transportation (Caltrans) will continue overnight lane closures on State Route 87 (SR-87) for the SR-87 Pavement Improvement project. Up to two lanes will be closed overnight between Julian Street undercrossing and State Route 85 (SR-85) connector ramp, in the city of San Jose. The purpose of the project is to improve ride quality, enhance safety, and extend the service life of the pavement. The closures began in the Fall of 2023 and will continue Monday through Saturday, until the completion of the project. Project is scheduled to be complete Summer 2025

SOUTHBOUND/NORTHBOUND CLOSURES
(Between I-280 and SR-85, San Jose CA.)

NORTHBOUND - Weekend of September 22
SOUTHBOUND - Weekend of October 20

Map of the State Route 87 Pavement Improvement project area. The project includes the stretch of State Route 87 between State Route 85 and the Julian Street undercrossing in San Jose.

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.

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.

Project Scope

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.

Current Status

Construction anticipated to start in Summer 2023.
