The 4CP aims to make it easier and safer to travel around portions of San Leandro, San Lorenzo, Ashland, Cherryland, and Castro Valley that are currently divided by significant freeway infrastructure. The plan will recommend community-prioritized transportation projects and outline strategies to advance the highest priority improvements in the near-term.

The map below shows the 4CP study area limits, and highlights key corridors, freeway ramp intersections, and rail crossings.
