Segment One of I-75 modernization project in Oakland County resumes May 15Contact: Rob Morosi, MDOT Office of Communications
- This project to modernize I-75 to current standards will enhance safety and improve traffic flow.
- Improvements include reconstructing the three existing lanes and building a future high occupancy vehicle (HOV) lane in each direction, realigning ramps, and replacing bridges in the project area.
May 8, 2017 -- Weather permitting, the two-year, $90.8 million reconstruction project on I-75 in Oakland County will resume Monday, May 15. This investment between Coolidge Highway and South Boulevard includes reconstructing pavement, replacing bridges, and modernizing the I-75 Business Loop (Square Lake Road) interchange.
Starting May 15, two through-lanes will be maintained during peak travel times in each direction of I-75 between M-59 and Coolidge Highway. During the overnight hours, one lane will be open. This will allow crews to stripe the freeway and place temporary barrier wall for an upcoming traffic shift. It is expected by the morning of Friday, May 19, that two-way traffic will be sharing the northbound lanes, with two lanes open in each direction, to allow for the reconstruction of southbound I-75, along with bridge replacements where southbound I-75 crosses over Adams and Square Lake roads. Once the traffic shift is implemented, traffic will be prohibited from using the eastbound Square Lake Road entrance ramp to northbound I-75. Traffic will be directed to M-59 to access northbound I-75.
Other ramp closures include the northbound I-75 exit to westbound Square Lake Road, the eastbound M-59 ramp to southbound I-75, and the southbound I-75 ramps to and from Adams Road. Detours will be posted for all ramp closures.
During the traffic shift, southbound I-75 traffic will be able to access westbound Square Lake Road via a counterflow format (which means traffic flows in the opposite direction of the current ramp movement) using the existing eastbound Square Lake Road ramp to northbound I-75. Traffic using this ramp will be shifted to westbound Square Lake Road before the intersection with Opdyke Road.
This pattern is expected to remain in place until August, when traffic will be shifted onto the new southbound pavement to allow for reconstructing the final piece of northbound I-75 from Squirrel Road to South Boulevard. It is expected all lanes and ramps will be open in mid-September.
