M-15 Cass River Bridge
Posted October 6, 2021, by Nathan Holth (webmaster [at] historicbridges [dot] org)

This is interesting to see a salvage and reuse of R4 railing on a new bridge. I wish it would have been done on other bridges. Usually its only done on a limited number of repair projects or projects involving historic bridges.

So, this would have been what replaced the pony truss over the Cass River in Vassar. This, in turn, was replaced in 2015.

I've posted the latest StreetView from before it was replaced - which is from 2012.

Now, here's the StreetView for the bridge that's there now: https://www.google.com/maps/@43.3708732,-83.5807253,3a,75y,3...

Looks awfully similar, doesn't it?

The contractor, Hardman Construction, chose to retain the R4 railing from the previous bridge and re-used it for this one.
