With the excitement and promise of a new school year upon us, children may not be fully aware of their surroundings as they walk, bicycle, or bus to school. In some cases, students may be going to new schools and be less familiar with the traffic patterns. That is why we are asking parents and other drivers to leave early, stay alert, and be extra cautious in school zones. The first few weeks of school can be extra stressful as everyone gets back into their school time routines. Please be respectful of others and the rules of the road during this critical time.

The Public Works Department recognizes that the goal of zero traffic deaths is attainable, and that’s why we are a part of Vision Zero. To learn more about Vision Zero and how we are working together to improve safety in the communities we serve, visit www.contracosta.ca.gov/visionzero or tap the link in our bio.

Public Works, in partnership with Davidon Homes and its contractors, DeSilva Gates and MCH, has completed the installation of a new traffic signal at the intersection of Mt. Diablo Scenic Boulevard and Diablo Road/Blackhawk Road. The traffic signal was activated and fully operational on Tuesday, August 11, 2026.

This new traffic signal replaced the existing three-way stop signs. The signal project also added a dedicated right turn lane at the T-intersection for southbound Mt.

These improvements were jointly funded by Davidon Homes (as mitigation for its Magee Preserve development), the Town of Danville (traffic mitigation funds), and the County (Local Road Funds – Gas Tax).
