US-23 Corridor - US-23/M-14 to Silver Lake Road, Livingston and Washtenaw Counties

Project Overview

In 2016-17, the Michigan Department of Transportation (MDOT) will improve the busy US-23 corridor from the US-23/M-14 west interchange north to Silver Lake Road. The work, which underwent an Environement Assessment (EA) study in 2014-15, includes:

  • Pavement repairs, including upgrading the median shoulder along US-23 between US-23/M-14 and Silver Lake Road;
  • Bridge replacement at 6 Mile Road, 8 Mile Road and N. Territorial Road;
  • Bridge repair at Joy Road and Warren Road;
  • Ramp upgrades at N. Territorial Road, 6 Mile Road, 8 Mile Road and at M-36; and
  • Installation of additional Intelligent Transportation System (ITS) hardware, including cameras and electronic message boards.

As part of the project, MDOT will place an Active Traffic Management(ATM) system along US-23 between US-23/M-14 west interchange and M-36 as a way to use innovative technology to manage peak-hour congestion. This system would utilize the upgraded median shoulders on US-23 to help improve traffic flow and increase safety along the corridor. Lane control signs will let drivers know when the system is active. The ATM will be monitored by MDOT’s Statewide Transportation Operations Center), through the use of expanded Intellegent Transportation System technology and with assistance by the Freeway Courtesy Patrol.

The Federal Highway Administration has granted a Finding of No Significant Impact (FONSI), clearing the project for design and construction.
