The Road Dust Institute (RDI) has changed its name to the Unpaved Roads Institute (URi) to better reflect the increased interest general unpaved road management issues. We would like to welcome you to our new website.  First conceptualized in 2008, we are continually evolving with input and support from our founding partners and the Federal Lands Highway of FHWA.  Today, URi is ready to assist industry, local governments, and private landowners with the design and maintenance of our nation’s unpaved roads.
