Notable Project Features
- Widening of existing bike lanes

- Fresh roadway striping
- Bicycle signage
- Traffic Signal Bicycle Detection Cameras
- Green ("high-visibility") pavement markings

what is a bike box?
A bike box is a designated area marked at the head of a traffic lane that provides cyclists with a safe and visible way to get a head of queuing vehicles at signalized intersections while waiting on a red light.
Bike boxes assist cyclists through intersections, particularly when needing to make left-turns. Bike boxes can be found at these three intersections:
- Diablo Rd / Camino Tassajara
- Diablo Rd / El Cerro Blvd
- Diablo Rd / Green Valley Rd
