Regional Mobility Grants Program

The Regional Mobility Grant program supports local efforts to improve transit mobility and reduce congestion on our most heavily traveled roadways. The program has provided $143.5 million to support local projects since 2006. 

Funded local projects include:
  • New transit services that connect urban centers.
  • Park and ride lots and expansions.
  • New buses.
  • Rush-hour transit service along congested corridors.
Authorization for the Regional Mobility Grant program is supported in statute by RCW 47.66.030.
