I-94/I-69 over Black River

2011 – 2012

  • Total Project Investment: $89 million
  • Location: Port Huron, MI

This landmark project involved the replacement of three structures on I-69/I-94 over the Black River in Port Huron, MI. The project also included 2.13 miles of freeway reconstruction, interchange reconstruction at two interchanges, ramp connections at the maintenance garage and proposed future Welcome Center, storm sewer and culvert replacement, permanent signing, MITS installation, wetland mitigation and site grading for a relocated Welcome Center

C.A. Hull was responsible for removing the existing structure on I-69 over the Black River and replacing it with three new 1,350 ft. bridges, one carrying I-69 to Pinegrove Ave, and two carrying eastbound and westbound I-69 traffic. The three new river bridges spanned over a 250-foot section of navigable waterway and a significant low-lying wetland, which lead directly into the Blue Water Bridge International Crossing. The eastbound structure carries a pedestrian sidewalk separated by traffic barrier. The bridges included texture on the piers and decorative steel wave railing on the deck with scenic outlooks.

“A unique aspect of this project involved the underwater demolition of footings, tremie, and piling,” said Jay Desai, who was the C.A. Hull Project Manager on this project.

Work on this project was completed in two construction seasons with no shutdown during the winter of 2011-2012.
