Work On Diablo Road To Start Monday, Part Of Larger Diablo Road Improvement Project

DANVILLE, CA — The town of Danville is conducting location testing, also known as potholing, along a segment of Diablo Road starting Monday.

From Monday through Friday, traffic will be limited to one way at a time between 9 a.m. to 2:30 p.m. from Fairway Drive to Avenida Nueva. Motorists should expect periodic traffic delays in the area for at least four days. Flaggers and signs will help guide them through the area.

The potholing precedes the Diablo Road Pedestrian Trail and Drainage Improvements Project, which will construct the final 0.9 mile of a 2.1-mile, 8-foot-wide Class 1 multi-use trail along the southern shoulder of Diablo Road. This aims to improve connection between Green Valley Road and Blackhawk Road, and expand access to Mount Diablo State Park.

Full construction is expected to begin later in the fall and continue through December 2026. Work will be paused during the rainy season from November through March.

Changeable message boards will be posted 72 hours in advance to notify the public of scheduled work. for more information, contact Development Services at devserv@danville.ca.gov or 925-314-3310, or visit danvilletowntalks.org/diablotrail.
