“State DOTs are overwhelmingly focused on innovative solutions to address the transportation issues of today and tomorrow, meeting challenges involving climate change, equity, resiliency, and safety,” said Jim Tymon, Executive Director of AASHTO. “The America’s Transportation Awards program shows just how they’re doing that. Whether on foot, in a vehicle, on two wheels, or by rail or transit, state DOTs are continuing to advance a safe, multimodal transportation system.”
Eighteen projects in the Mid America Association of State Transportation Officials (MAASTO) region were nominated by eight states for this year’s competition. The following two projects in the Michigan Contractor & Builder area were winners of the regional America’s Transportation Awards.
The $60-million design-build project improved safety and capacity on the busy north/south route by rebuilding and widening 2.5 miles of I-75, replacing the previous full cloverleaf interchange at M-46, and filling a 22-foot dip on I-75. The backfilling of the dip eliminated the need for multiple vertical curves on the roadway and eliminated the need for a pump station, which made I-75 more reliable during storm events. The project also included the addition of roundabouts, the reduction of exit/entrance ramps from eight to four, and more green space on the south side of the interchange.
“The completed project is a much safer and easier to use system,” said Brian Ulman, Davison TSC Manager (former Bay City TSC Construction Engineer). “The entrance and exit ramps are safer to use. The new roundabouts are safer intersections, as traffic crashes that may occur will be at lower speeds and a smaller angle of incidence resulting in less serious accidents. With the elimination of four ramps, the layout will be simpler for traffic exiting and entering I-75 and M-46.”

The adaptive signal control technology optimizes traffic flow and reduces peak travel times by allowing traffic signal timing to adapt to actual traffic conditions in real-time. MDOT also improved pedestrian signal timing, upgraded sidewalk ramps to ADA standards, installed CCTV cameras at key intersections, and added a travel time monitoring system that enables both real-time and historical analysis of traffic operations.
“So far we’ve seen some great benefits from this project, including more reliable travel times,” said Victoria Swanson, North Region Assistant Operations Engineer. “This has also benefitted some bicyclist crossings as well as pedestrian crossings, as we’ve been able to implement leading pedestrian integrals which improves pedestrian safety. … Overall, it’s really improved traffic flow and increased the traffic time reliability throughout the Traverse City area.”
