Since 1922, Toebe Construction has been building the transportation infrastructure that supports the economies of Michigan and Ontario. Continuing the traditions instilled by Walter Toebe himself, and carried out today as a 3rd generation family-owned and operated business, our mission is to lead the heavy civil construction industry by delivering exceptional value and opportunity for our clients, employees, partners, and the communities in which we work. With 100 years of experience in heavy/highway construction in Michigan, Toebe has self-performed the construction of major portions of many of the most recognized transportation infrastructure projects, in addition to a host of less-prominent but equally significant public works across the state. Some of the more noteworthy projects include the Zilwaukee Bridge, the John C. Lodge Freeway (M-10), the U.S. Blue Water Bridge Plaza, the I-696/Woodward Avenue interchange, the I-75 Gateway IV project, and rehabilitation work on the Mackinac and Ambassador bridges. From the Upper Peninsula, to Detroit and Grand Rapids, Toebe has played an integral part in cost-effectively building the network of roads and bridges that link communities and support economic development across the region.
