Great Lakes Engineering Group (GLEG) was privileged to work together with Michigan Department of Transportation and a host of other consulting firms as part of an As-Needed service to rehabilitate and reconstruct the I-75 Corridor from Sibley Road in Brownstown Charter Township north to Clark Street in the city of Detroit.
The scale of this project was massive including a significant amount of bridge work on over 18 structures over the 13 mile stretch of I-75. In order to complete the work, the contractors had to close southbound I-75 for 2 years while they reconstructed and replaced bridges along both northbound and southbound sides of the road while maintaining northbound traffic throughout the duration of the job. In addition to the bridge work, concrete pavement patching and several bridge approaches were replaced in order to improve the ride quality and extend the service life of the roadway. Sewer improvements were made and both directions of I-75 were replaced from Springwells Street to Clark Street in Detroit to accommodate future expansion and the Gordie Howe International Crossing. This service also included ancillary items such as freeway lighting upgrades, noise wall construction, ITS installations, and pavement markings.
Our GLEG team provided a diverse assortment of services on this project. Our construction field staff provided oversight for bridge deck removals, welded and bolted structural steel repairs, pin and hanger replacements, reinforcing steel takeoffs and installation, substructure concrete placement, bridge deck pours, and barrier wall installations. Our team also provided oversight of concrete patches, polyurethane injection under concrete, guardrail installation, and soundwall rehabilitation. GLEG also provided MDOT with engineering assistance including office technician services, technical proposal administration, project photography, recording in the pavement historical database, and ombudsman services where we responded to thousands of public concerns through phone, email, social media, and in-person meetings.
