Interstate 80 Gilman Interchange Bicycle-Pedestrian Overcrossing

Pushing baby strollers, zipping along on bicycles, jogging, ambling and striding, people are using the newly opened bicycle-pedestrian overcrossing at the Interstate 80 Gilman interchange to cross over without the risk of getting mowed down by a car.

Almost three years after Caltrans broke ground, the overcrossing opened to the public May 11, giving folks on two wheels and two feet the opportunity to literally rise above the turning conflicts and other challenges currently presented by the interchange.

Those challenges will be resolved when Caltrans completes a double roundabout under construction at the interchange in early 2025. One temporary roundabout is already in place, and drivers have taken to it like ducks to water.

Repair Work Underway on Niles Canyon Road (SR-84) in Sunol

Caltrans is repairing Niles Canyon Road (State Route 84) between Old Canyon Road and Main Street in Sunol. Work began the week of June 17, 2024.

A new bridge on piles will be constructed at the location of the slip-out in the eastbound direction where a portion of lane collapsed into the creek four months ago.

Work will be performed between 8 p.m. and 5 a.m. Monday through Friday. Full closures will be in effect while work is being performed. Motorists should detour via Interstate 680 during these hours.

The roadway will reopen with one-way traffic control every morning. Work is scheduled to complete by the end of the year. Every effort will be made to open both lanes of Niles Canyon Road (SR-84) as soon as November if possible.

Unforeseeable events such as rain will affect the schedule.

One-way traffic control has been in effect on Niles Canyon Road since February when the ground under the road deteriorated, causing a portion of the highway to collapse.

Caltrans thanks the public for your patience as we work to repair the damage caused by the slipout.
