 As M-29 approaches Marysville the road turns back inland from the river where it travels through the southeastern side of Marysville before terminating at an intersection with I-94 Business Loop which leads into Port Huron.Prior to the implementation of the U.S. Highway System, M-29 existed as a route that connected the Lansing area to Indiana via Charlotte and Marshall.In 1926, when the U.S. Highway system was created, US 27 overtook the alignment that M-29 had previously occupied.
