Question 1

What are the project boundaries?

Accepted Answer

The project area is M-29 (23 Mile Road) through the I-94 Interchange. The project is 0.3 miles long.

Question 2

What is the project schedule?

Accepted Answer

Work begins on June 29, 2026 and is expected to finish during November 2026.

Question 3

What traffic impacts can motorists expect?

Accepted Answer

Drivers can expect continuous lane closures of M-29 (23 Mile Road) and I-94 for the duration of construction. At a minimum, one lane of travel in each direction will always be open.

Drivers will also see ramp closures of eastbound M-29 (23 Mile Road) to eastbound I-94 and of westbound M-29 (23 Mile Road) to westbound I-94 for a period during construction. During this period, a posted detour will be signed to utilize the 21 Mile Road Interchange for access to I-94.

Question 4

Will there be any noise during the bridge project?

Accepted Answer

There will be limited noise disruptions during this project. The majority of the work will occur during the day, but for safety reasons, some work will be required to be completed at night. The project will minimize the noise as best as possible.

Question 5

Why is this project necessary?

Accepted Answer

The M-29 (23 Mile Road) Bridge over I-94 was originally constructed in 1963, received preventative maintenance work in 2002, and now requires further maintenance to keep up with its age.

In addition, sidewalk connections already exist on both sides of the interchange but stop at the I-94 ramp terminals. Dirt paths exist in various areas of the interchange, showing that pedestrian demand for a crossing already exists.

Furthermore, Chesterfield Township’s master plan calls out this corridor as a critical connector where sidewalk gaps need to be filled. As there are no other non-motorized connections across the freeway anywhere in the area, and this bridge is the only one in the area that can accommodate the addition of a sidewalk without widening the bridge, modifications to the bridge to allow for a sidewalk are being implemented.

Question 6

Will the dimensions/locations/lanes of the road be changed?

Accepted Answer

No, the dimensions, location, and number of lanes that exist within the project will remain the same. However, a barrier protected sidewalk will be added on the north side of M-29 (23 Mile Road) through the I-94 Interchange.

Question 7

How much does this project cost?

Accepted Answer

The overall project cost is projected to be just over $3.5 million.

Question 8

How can I report any issues or concerns while the project is underway?

Accepted Answer

If you have any questions or concerns regarding the project, please contact the Macomb TSC at 586-421-3920 or at MDOT-MovingMacomb@michigan.gov
