SR37 Corridor Projects
The future of the State Route 37 Corridor requires finding solutions to traffic congestion and periodic flooding. But it will also require balancing transportation needs with protecting and enhancing sensitive marshland habitats. Planning a long-term solution presents an opportunity to provide bicycle, pedestrian, transit, and carpool options for all travelers. Caltrans is working with its partner agencies, The Metropolitan Transportation Commission and the four North Bay County Transportation Agencies to develop a more resilient corridor.
But We Need Your Help!
Please provide us with your thoughts and suggestions on planning a more resilient, reliable, safer, facility for all travelers!
