The Wayne County Airport Authority is set to begin a multi-project construction program on Detroit Metro Airport grounds that will impact traffic flows around both terminals for the next few years. The projects first phase was scheduled to start Monday, Jan. 8.

The program is centered on rehabbing roadway tunnels on Dingell Drive. The project is split up into multiple phases -- the first one will start this month and run through February. The second phase will start in March 2024 and run through mid-2025.

The second project is in the planning stages and will address the rehabilitation of exterior drainage and waterproofing systems of the south and north tunnels. WCAA plans for the second project to start in 2025.

Construction will continue year-round until the anticipated conclusion in 2027
