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.

Current biennium
During its session in 2015, the Washington State Legislature approved 39 new and continuing Regional Mobility Grant projects across the state for the 2015-2017 biennium, appropriating $66.25 million in state funding. The complete list is below, and a map of both new and ongoing projects (pdf 209 kb) is also available.

Information for prospective applicants for the 2017-2019 biennium
Applicants are required to submit a letter of intent (pdf 92 kb) prior to application submittal detailing the anticipated project, its location and its use of state highways. The letter helps identify early in the application process whether there are opportunities for maximizing state investments. By collaborating with WSDOT and our partners, we can help you develop project proposals that maximize benefits across the transportation system.

If you are interested in applying, please follow the instructions in the letter of intent form (pdf 92 kb) and submit it to WSDOT by Monday, June 13.
