Motorists who must travel Interstate 75 between Coolidge Highway and 13 Mile Road, as well as those traveling on surface streets near the freeway, should plan ahead and expect delays when work is scheduled to begin March 8.

Rob Morosi, a spokesman for the Michigan Department of Transportation, explained that the start of the second segment of the project was delayed about a week.

Starting at about 7 p.m. March 8, southbound traffic, just south of Adams Road, will go from three lanes to two. On the morning of March 9, Morosi said, motorists should expect that the freeway will be down to two lanes of traffic on both the northbound and southbound sides.

Northbound traffic is scheduled to shift to to southbound lanes, when two lanes of traffic for both north and southbound lanes will be on the southbound side, a couple of weeks after work starts. This will give crews time to place the temporary barriers between the northbound and southbound lanes, Morosi said.

This shift will be in place until Thanksgiving, when work on the 8-mile, $224 million segment of the roadway — which includes 18 bridges — is scheduled to be complete.

Both sides of the freeway will be open during the winter months of 2019-2020 until work begins on the southbound lanes and traffic is diverted to the newly constructed northbound lanes in 2020.

An MDOT press states that temporary exits will be maintained for northbound traffic at 14 Mile Road, Rochester Road, Big Beaver Road and Crooks Road. A crossover at the Corporate Drive entrance ramp, near Crooks Road, will allow traffic to access northbound I-75 while traffic is shifted onto the southbound lanes. These temporary movements will be closed for a limited time during the construction season while crews are working within the vicinity.

Final pavement markings for the 8-mile segment through Troy will be finished in 2021.

The $127 million first phase of the project, the addition of one lane to northbound and southbound I-75, covered 3 miles of the freeway, between South Boulevard and Coolidge Highway through Bloomfield Township, Auburn Hills and Troy. That began in August 2016. The project’s first phase of construction also replaced five bridges, reconfigured the interchange at Square Lake Road and made improvements to the Adams Road carpool lot.

That work was completed in 2017.

MDOT awarded the $224 million second phase of the I-75 modernization project to Walsh-Toebe Construction.

Federal funding covers about 80 percent of the costs.

That stretch of freeway carries up to 174,000 vehicles per day.

Prep work on the third and final phase — from 13 Mile Road to Eight Mile Road, is scheduled to start this fall. The anticipated completion is fall 2023.
