On a bike ride back to center city recently from Chestnut Hill I saw this cool tiny plaque on a bridge over the Monoshone Creek. It's right where Forbidden Drive connects with the Wissahickon Bike Trail. I attempted to do some digging, as one does, and I couldn't find any info about it! This amazing website called Bridge Hunter has every other bridge known to mankind, but not my little dinky County Bridge 1830. Alas. Below is its location and the last photo of the set is also on the ride home - Strawberry Mansion Bridge - but that one is hard to miss.
