I-75 at Square Lake

2016 – 2017

  • Total Project Investment: $89 million
  • Location: Bloomfield Township, MI

The goal of the I-75 Modernization Project was to improve the freeway from M-102 to south of M-59 in three segments. Segment 1 of the project was 2.69 miles in length and included pavement replacement with the addition of an HOV lane and included the complete redesign and construction of the I-75/Square Lake interchange in Bloomfield Township, MI.

C.A. Hull’s portion of the project consisted of the design and rebuild of the Squirrel Road bridge over I-75, which was completed in just a few months, as well as the addition of three new bridges within the interchange, including a tri-level flyover.

The Squirrel Road bridge, as designed, consisted of two spans with a sidewalk and numerous aesthetic treatments including decorative pilasters, monument walls, and brick texturing. C.A. Hull’s project team excelled at using shut down times and by working in close coordination with utility companies to complete all bridge work in 90 days.

The interchange work included new bridges for southbound and northbound I-75. Due to an innovative change in alignment for the new I-75 roadway, both bridges were able to be constructed simultaneously and with no effect on the existing traffic.

The existing tri-level flyover which was replaced with a 4-span tri-level bridge over was demolished in one weekend for safety reasons between stages of reconstruction on the ramp.
