LAFAYETTE, CALIFORNIA – If you drove into downtown Lafayette yesterday or over the weekend, you might have noticed big flashing signs warning about delays.
Why the warnings?
A city road restriping project is beginning Monday, April 13, with work first hitting downtown Mount Diablo Boulevard before moving on to Moraga Road and several other Lafayette streets in the coming weeks.
City officials say the work will require intermittent lane closures, traffic control, and temporary loss of some parking spaces during active construction periods.
Here’s what to expect in terms of delays.

Where work starts
According to the City of Lafayette, the contractor Central Striping Service was scheduled to begin Monday on Mount Diablo Boulevard, specifically between Mountain View Drive and First Street. After that, crews are expected to continue to Moraga Road.

The broader project also includes restriping on Stanley Boulevard and Quandt Road, along with curb repainting work on parts of First Street, Deer Hill Road, and Happy Valley Road.
When to expect delays
The city says traffic control will generally be in effect between 9 a.m. and 2:30 p.m. during active work phases. That means midday drivers are the most likely to run into slowdowns, lane shifts, flaggers, or blocked curbside parking.
Officials also noted that the work may appear stop-and-start. In other words, once the project begins, crews may not be working continuously in the same location every day, and residents may see stretches of inactivity between phases.

Streets affected by the project
The city says the project includes:
- Mount Diablo Boulevard between Mountain View Drive and First Street
- Moraga Road between Mount Diablo Boulevard and St. Mary’s Road
- Stanley Boulevard between Camino Diablo and Barott Road
- Quandt Road between Stanley Boulevard and Plymouth Road
- First Street between Deer Hill Road and Mount Diablo Boulevard, and between Moraga Boulevard and School Street
- Deer Hill Road between Happy Valley Road and Laurel Drive
- Happy Valley Road between Cosso Court and east of Panorama Drive
How long it is expected to last
If the weather cooperates, the city estimates the restriping project will continue through mid-May. Emergency vehicles will still be given access during construction, according to the city’s update.
The project was awarded by the Lafayette City Council in January at a contract amount of $217,682, according to the city’s construction page.

For anyone heading through downtown Lafayette this week, the safest bet is to avoid assuming normal traffic flow in the late morning and early afternoon. Downtown Mount Diablo Boulevard is first up, so that corridor is the place most likely to see the earliest impacts. Moraga Road should follow after that.
Drivers should also watch for temporary no-parking signs, cones, workers, and changing traffic control setups as crews move block to block.
