Local agencies need cost-effective and durable turfgrass seed mixes to ensure grass coverage remains optimal along roadsides. In a recent study, researchers analyzed the performance of grass seed mixtures and planting costs, recommended region-specific mixes and developed a cost estimation tool for local agencies to be confident in their roadside vegetation choices.

Wind Impact and Breakaway Performance of Roadside Message and Conflict Warning Signs
Roadside dynamic message signs with breakaway components handle wind-induced vibrations adequately for an almost 24-year fatigue life. Rural intersection conflict warning signs vibrate noticeably under wind forces and require design changes to resist fatigue damage.
These are the results of a new research study sponsored by the Minnesota Department of Transportation that investigated the effects of wind loading on roadside message and conflict warning signs.

Regional effort tests turfgrass performance in cold climate states
This article was originally published in Catalyst, April 2020.
Vibrant green grass along roadways is a common sight across urban and rural landscapes in Minnesota and many other states, but its survival is a significant challenge—especially in cold climates. Roadway salt and other stressors can cause turfgrass installations to fail, requiring expensive reseeding or sodding efforts.
