US-23 Flex Route Project


Starting in 2016, road and bridge improvements will begin along US-23 in Washtenaw and Livingston counties between M-14 and Silver Lake Road. As part of this $92 million investment, MDOT will implement the Flex Route traffic management system along the highway between M-14 and M-36. 

Once construction begins, work is expected to continue through the winter and into 2017. Additional lane closure and detour notices will be provided as the project progresses. The goal is to complete the project by the end of 2017.

Project information is available on the US-23 Flex Route project website at
