The first span has a cantilever design, and it was opened in October, 1938. The second span has a tied-arch design, and it was opened in 1997. The span is 871' with a clearance of 150' above the river. Each of the main piers for the original bridge consist of two 26' caissons sunk 95' below the water level to bedrock. [MDOT1]

The engineers wanted to build a cable-stayed bridge. But the Michigan State Historic Preservation Office and the public insisted on the arch design because its appearance complements the original bridge. [Historic Bridges]

[Upbound must mean upstream. In this case, northbound.]

James Deeds Currently CN, tries to have the regular 524 crew switch dunn’s 5 days a week. 524 duties are switching in tunnel yard, interchanging with the csxt. Rescue work. Also cabbing to Flint to bring a 504 type train east. Sometimes going down the mt.clemens, when 533’s Moterm duties are more in demand. 524 is pretty much an all purpose job in Port Huron. Regular crew works Sunday to Thursday, extra board crews fill job on fri/sat as needed.

I know people have posted in the past about questions of how often Dunn Paper gets served in Port Huron. So, heads up to anyone in the PH area, they’re switching out Dunn right now.
