Document Description
The purpose of this project is to provide roadway safety improvements. This project consists of installing edge line rumble strips, new lighting, and speed warning signs on an existing 1.3-mile segment of Byron Highway. The edge line rumble strips will be installed along the entire project segment; streetlights and speed feedback signs will be placed along an approximately 0.6-mile curved segment; the streetlights will be spaced approximately 200 feet apart along the sides of the road and connect with electrical conduit to approximately two new service pedestals. The maximum depth of excavation will be approximately 6-10 feet for streetlight installation and a maximum of 3 feet for trenching the electrical conduit. Vegetation trimming may be necessary. The project is in the East Contra Costa County Habitat Conservation Plan (HCP) and will comply with HCP requirements. Real estate transactions may be necessary. Construction is anticipated to begin May 2027 and take 8 weeks to complete. Temporary traffic control is expected to last for the duration of the project. Emergency vehicles will have access at all times.
