New segment of I-75 freeway widening near Detroit set to begin

The current segment is part of a larger modernization of I-75 that will eventually rebuild and widen 18 miles of the highway with HOV lanes in each direction, including replacing bridges, according to MDOT. The third and final segment is scheduled to begin in fall, be completed in 2023 and cost $629 million. It will include a 4-mile drainage tunnel that will be 14 feet in diameter to prevent the freeway from flooding.

The entire project is estimated to cost $944 million.
