About LRRB

A Rich Tradition

Established in 1959 through state legislation, the Local Road Research Board (LRRB) has sponsored more than 200 individual research projects over the last 15 years. Current
LRRB-funded research falls primarily into the following categories: design, construction, maintenance/operations, environmental compatibility, administration, and implementation.

Grassroots Involvement

The transportation practitioners who are responsible for county highways and city streets best understand the problems and challenges in providing safe, efficient roadways. The LRRB makes it easy for them to participate in setting the research agenda.

How the LRRB Works

Transportation practitioners submit ideas to the LRRB, which selects and approves proposals. The Minnesota Department of Transportation (MnDOT) 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.

Making a Difference

The LRRB’s current research includes projects to explore better methods to inspect and maintain timber bridges, look for best practices in applying Complete Streets principles to design, and to evaluate the impacts of implements of husbandry on our roads and bridges.

Annual Program At-A-Glance

LRRB creates an annual program report to list and describe projects selected for that fiscal year. View the current LRRB At-A-Glance, or view past reports:
