Thank You!

MDOT and the project team would like to thank the motorists and communities for your patience.  We were able to open I-75 between Coolidge Highway and South Boulevard in only 110 days!

Road construction projects are challenging.  We were able to accomplish all this including the following improvements, while two lane of freeway remained opened the entire time.

-Replaced an aging Squirrel Road overpass in 90-days

-Rebuilt over 3-miles of interstate freeway

-Reconfigured the enourmous Square Lake interchange to modern geometric movements for improved safety

-Improved the drainage to ensure safe conditions during weather events

-Constructed community developed aesthetics

We opened traffic today, but there is a little work left to be done for project completion.  We completed work safely to allow all lanes and ramps to open early.  Pavement markings, for instance, and the Adams carpool lot will be completed later in the month.  Next spring, the tree planting and landscaping project will start to replace the trees.

So while there is a little work left to be done, rest assured the days of consistent lane closures are in the past.  We appreciated your patience as we worked to improve this very important section of I-75.  Have a safe holiday weekend.  Happy driving!


Ahead of Schedule!  All lanes to open September 1st

In time for the Labor Day holiday weekend, crews will open all lanes and ramps on September 1st.
