A practitioner-ready guide for converting severely distressed low-volume paved roads to improved, easily maintained gravel roads. The guide includes decision-making tools and an online webinar for training
Minnesota Toward Zero Deaths has awarded its annual Engineering Star Award to Renae Kuehl, LRRB research implementation and outreach consultant, in recognition of her work on safety-related initiatives such as […]
Researchers have further refined a quick and innovative pothole repair method using taconite mixtures. The recently completed study was funded by the Minnesota Local Road Research Board in collaboration with […]
Using a sophisticated driving simulator, LRRB-sponsored researchers determined that 400 and 600 feet of sight distance is insufficient at rural intersections. Drivers performed much better with 1,000 feet of sight […]
Positive offset left-turn lanes can significantly reduce crashes by improving left-turning motorists’ visibility of opposing through and right-turning traffic. This is the findings of a recently completed LRRB study, which examined decades of research and reviewed guidance from 23 state DOT road design manuals to develop Minnesota-specific guidelines to improve sight lines at intersections, particularly those of left-turn lanes.
The Local Road Research Board thanks outgoing board members Tim Stahl (Jackson County) and Lyndon Robjent (Carver County), who recently completed two, four-year terms of service. The board welcomes new […]
The LRRB is hosting Session #22 on Wednesday, March 4, 2020 from 10:00 – 11:00 a.m. in Meeting Rooms 2-3 at the Saint Paul RiverCentre.
The Minnesota Local Road Research Board has published a new guidebook to help local agencies get started on developing a consolidated asset management system. The guide addresses the particular needs of smaller groups to effectively and optimally manage their roadways, buildings, vehicles, equipment and other assets.
A recently completed research project, funded by the LRRB and MnDOT, is featured in the January 2020 edition of Roads & Bridges.
In December, the Minnesota Local Road Research Board met and funded 13 new research projects to address issues facing the Minnesota transportation community, including vehicle-pedestrian crashes and changes in how urban speed limits are set.
The Minnesota Local Road Research Board, through its Research Implementation Committee, has awarded funding to develop new educational and guidance materials in 2020 on nine transportation topics.

A Light Surface Treatment, also known as a bituminous surface treatment, is a relatively new method for preserving a gravel or dirt road surface. The LRRB developed a half-day training curriculum to help counties and townships select the right treatment and successfully apply it.
A recent LRRB project, “Strategies for Effective Roundabout Approach Speed Reduction,” provides the methodology to select, install, and evaluate treatments at different locations. This project had two goals: To analyze […]
Local transportation agencies are facing severe challenges in keeping roads safe and in good repair. Among those challenges are aging infrastructure, increasing material costs, and stagnant or decreasing funding levels. […]
Project will develop guidance on preparing for and adapting to connected and automated vehicle (CAV) technology, including policy and infrastructure development. Researchers may develop a local agency repository for CAV resources […]
This project will develop a resource guide about the effectiveness (application & cost) of fog sealing over chip-sealed roads. It will include a survey/interview of local agencies, followed by analysis […]
This project will develop a resource, possibly a quick reference guidebook, for practitioners to better understand pavement performance of overlays and new construction related to ride quality and reflective cracking. […]
This quick reference guide helps local agencies select appropriate crosswalk treatments based on roadway type, vehicle volumes and posted speed limits.
