Fremont Blvd work still delays drivers and AC Transit riders

Drivers crossing Fremont’s Centerville district are still dealing with an active construction zone: the eastbound lane on Fremont Boulevard between Thornton Avenue and Bonde Way remains closed around the clock while the Centerville Complete Streets project moves ahead.

The City of Fremont says the closure is tied to sidewalk, bike lane and driveway improvements. Westbound Fremont Boulevard traffic is not affected in this stage, and existing driveways are still expected to remain open. Even so, the city says drivers should expect moderate delays near the Thornton/Fremont intersection, especially between 8:30 a.m. and 4 p.m.

What is still happening on the street

The city says temporary pedestrian and bicycle detours are still in place at the Thornton Avenue and Fremont Boulevard intersection so crews can keep working at the corners. That matters for anyone walking to school, transit stops, nearby shops or homes in the area. The city also says traffic signal sensors may be affected during construction, which can slow traffic even when volumes are light.

For commuters, the main point is that this is not a finished project. It is still an active work zone, and the city continues to warn drivers to watch the posted temporary striping and signs. If possible, alternate routes are still the safer bet during busy travel windows.

Summer milestones are still ahead

The city’s project page still points to a summer schedule for the next major steps. Fremont Boulevard and Thornton Avenue intersection improvements are listed for mid-July, traffic signal work along Thornton Avenue and flashing beacons on Fremont Boulevard are listed for the end of July, and repaving of Thornton Avenue, Fremont Boulevard and Peralta Boulevard is listed for mid-August. Final cleanup is currently scheduled for the end of August.

A Spring 2026 city newsletter also says construction is underway for the Centerville Complete Streets project, reinforcing that this is an ongoing infrastructure buildout, not a completed one.

Transit riders have a separate disruption

AC Transit has also posted a Fremont Boulevard stop closure tied to the same construction corridor. The alert affects Route 231 to Milpitas BART and is listed for weekdays from June 22 through July 17. AC Transit says the closure is due to construction work not caused by the agency, and it lists alternate stops nearby.

For Fremont residents, the practical takeaway is simple: this corridor is still under construction, and the disruption is affecting both drivers and bus riders. Anyone traveling near Thornton Avenue this summer should check for detours, stop changes and short delays before heading out.
