Trunk Line Bridge
Posted December 12, 2021, by Mike Kerkau (mjkerkau [at] gmail [dot] com)

At the time of the inception of Michigan's State Highway system in July 1919, this served M-19.

In 1922, it would also serve M-21.

In 1926, M-19 would be re-routed off this route, but M-21 remained.

Then, around 1932, M-21 would be re-routed north onto Lapeer Road.

So, all in all, this served as a Trunk Line bridge for about 13 years.
