Niles Canyon Road Full Closure Planned This Weekend

UNION CITY, CA — If you typically use Niles Canyon Road, also known as State Route 84, make alternate plans for this weekend. It will be closed in both directions from Friday evening to Monday morning.

You can also expect Mission Boulevard to be busier than usual as it is a designated detour.

The closure will extend from Palomares Road in Fremont to Main Street in Sunol.

Caltrans scheduled the closure for work on the Alameda Creek Bridge.

During the closure, a contractor will work around the clock to install polyester concrete overlay on the existing Alameda Creek bridge deck in both the eastbound and westbound directions. The work includes removal of existing asphalt concrete surfacing on the deck, preparing bridge deck surface to receive polyester concrete overlay, furnishing polyester concrete, and placing polyester concrete overlay.

Once the concrete is cured, a temporary striping will be placed, and the road will be open to traffic. There will be portable changeable message signs informing drivers of the closure.

Niles Canyon Road will close at 8 p.m. on Friday and is scheduled to reopen at 5 a.m. on Monday.
