Michigan Department of Transportation’s $46 million project rebuild an aging segment of I-75 through Saginaw County, to improve traffic flow and Michigan’s economic strength. It incorporated innovative techniques and warranties on pavement materials and workmanship to save more than $2 million in project costs and a projected $200,000 a year in future maintenance costs. Throughout the project construction crews provided an extra peak-direction travel lane, which saved the public $30 million in traffic delay costs. And community input resulted in the installation of a decorative sound wall, a first in that county. The completed project also included a fourth travel lane in each direction that further improves travel, to save a projected $1 million a year in user delay costs.
