About the Local Road Research Board (LRRB)

What is the LRRB?

Established in 1959 through state legislation, the Minnesota Local Road Research Board (LRRB) sponsors transportation research particular to the design, construction, maintenance/operations, environmental compatibility, administration and implementation needs of cities and counties.

How the LRRB works

Transportation practitioners from local agencies submit ideas to the LRRB, which selects and approves proposals. The MnDOT Office of Research & Innovation provides administrative support and technical assistance. Researchers from MnDOT, universities and consulting firms conduct the research, and the LRRB monitors the progress.

Research sponsored by the LRRB helps to improve the quality of Minnesota’s transportation systems. The impact of this research multiplies as more and more engineers see potential applications through the technology transfer efforts of LRRB’s Research Implementation Committee.
