Isabella Road Little Salt River Middle Bridge

...well, shoot. Looks like the county had, apparently, already replaced this one by the time I'd posted an entry for it last year. Replaced in 2018, per the new round of NBI inspections (and showing a new, different entry for a location isn't something they lie about).

StreetView will still show it for now; it hasn't yet updated. But in any case, here's one more to "X" off, Nathan.

There were some other counties that built stringer bridges using MSHD's unusual railing design that was normally reserved for use on truss bridges. Two examples:

The Little Salt River is winding and Isabella Road ends up crossing it three times; this is the middle of the three bridges.

In checking through records, I've found up to six examples of this unique-to-the-County bridge design that existed in Isabella County; now, only two, maybe three, remain.

Nathan has a detailed look at this one on Historic Bridges.

The other one for sure is on Pickard Road: http://bridgereports.com/1251192

The one I'm less certain about is on Rolland Road, south of the bridge linked here: http://bridgereports.com/1251147 The StreetView there is older and the bridge in question isn't listed; it's probably too small.
