    Why

    VTA crews are continuing construction on SR 85 in San Jose as part of the SR 85 Noise Reduction Program. Most work will occur at night to minimize daytime traffic disruptions, but it may result in noise in nearby neighborhoods.

    Community Impacts
    • Nighttime Noise (between 8 PM and 5 AM): Neighbors may hear construction noise from grinding, paving, and barrier installation.
    • Lane Closures: Expect temporary lane reductions at night between 8 PM–5 AM while work zones shift.
    • Stormwater Work: May involve visible excavation and equipment near medians and inlets.
    • Day Work: Minimal but includes electrical box removals and vegetation clearing.
