I-275 Rehabilitation – Roadway Design and Right-of-Way for MDOT

The MDOT selected DLZ for the design and preparation of construction documents for I-275 rehabilitation. It involved work on five miles of six-lane freeway, from Ford Road to Six Mile Road. It also included interchanges at Ford Road and Ann Arbor Road, in the Cities of Canton, Plymouth, and Livonia.

The tasks of the project included

  • Full right-of-way and roadway design survey
  • Complex maintenance of traffic plans
  • Extensive pavement evaluation
  • Crash assessment
  • Milling and overlay detailing
  • Culvert evaluation (visual and hydraulic assessment), replacement and upgrades
  • Shoulder reconstruction
  • Freeway signing replacement
  • Traffic signal modernization design

The I-275 rehabilitation project also included geometric assessments to evaluate opportunities to make required improvements, such as vertical clearance improvements, extensive coordination with MDOT staff to assess the impacts of pavement widening and its impacts on water quality and quantity to satisfy MEGLE’s MS4 requirements.

DLZ incorporated the plans for the rehabilitation of 20 bridges designed by MDOT staff. DLZ also prepared exhibits and assisted MDOT staff for the presentation at the project’s public informational meeting. This project was selected to pilot the incorporation of alternative technical concepts (ATC) for the maintenance of traffic (MOT). The MOT ATC was implemented to involve the construction industry in the efficient implementation of traffic staging during the construction phase of the project.
