Each year since 2009, the AASHTO Research Advisory Committee has held a competition to highlight high value research (HVR). All 50 states, DC, and Puerto Rico can submit HVR entries. Each of the four regions within AASHTO then select four HVR projects, resulting in the top 16 HVR projects or the Sweet Sixteen. Since 2013, additional projects are chosen to highlight in two topical categories, one being safety and the other varying each year.
The Montana DOT has won a HVR award in 2009, 2014, 2018, and 2020. In addition, Montana DOT has been recognized in the supplemental HVR topics in 2015, 2017, 2019, and 2021. The projects are linked below.
