Rapid City's diverging diamond interchange wins a regional America's Transportation Award.
Officials selected the intersection, located at I-90 and LaCrosse Street, from among 32 projects in 15 states.
As a medium-sized project costing between $10 and $100 million, it won in the Best Use of Technology and Innovation category.
“We are honored to earn a 2024 America’s Transportation Award for the I-90 & LaCrosse Street DDI project which was designed to improve safety and address future travel needs,” said Joel Jundt, SDDOT Secretary of Transportation. “The DDI project successfully increases vehicle capacity and reduces congestion and traffic delays particularly during the peak tourism season. Moreover, it ensures compliance with Americans with Disabilities Act regulations, improving pedestrian access between shops and hotels on both sides of I-90 which further bolsters the economy of South Dakota’s second-largest city and tourism destination.”
Officials will select 12 nationwide finalists in September, featuring the three highest-scoring projects in each region. Those top contenders go on to compete for the two America's Transportation Awards national prizes.
The awards highlight state DOT projects and their impact on the communities in which they are built.
