Stateline Highlights Unpaved Roads Research

Stateline, a national website covering trends in state policy, published a feature story on a recent WTI project on the pros, cons, and costs of converting low-volume paved roads to unpaved roads. In “Dirt Roads Help Some Cities, Counties Drive Down Costs,” Stateline interviewed Principal Investigator Laura Fay about her research for the National Cooperative Highway Research Program, which sought to explore how commonly and under what conditions transportation agencies are converting paved roads to unpaved roads. Through a national survey, the project identified 48 agencies that have completed conversions, 70 conversion projects, and 550 miles of converted roadway. Click here to read the Stateline article.

Winter Maintenance Work featured on Roads and Bridges Website

The August 29 issue of Roads and Bridges included an article written by WTI’s Anburaj Muthumani and Laura Fay on assessing the use of snowplow lighting for optimal safety. “Can you see me now?” highlights the work done by the research team for the Clear Roads Best Practices Guide for snowplow lighting. Led by WTI, the team has compiled these findings into a best practices guide for winter maintenance agencies. The guide and the project final report are available on the Clear Roads website ( To read the Roads and Bridges article, visit:
