Half Mound Bridge
Posted September 16, 2008, by Max Johnson

Doing research on the Historic American Records page on the bridge, and they have a little hand drawn map of where the bridge is. When HAER did the bridge, the name of the road it was on was Federal Aid Secondary road 1325. Today the road's name is Half Mound road and also carries highway 382.

However, using the picture on HAER site, and a sattlite map, i found the bridge no longer exists. Originaly, the road swang around to the north, with the bend of the Delaware river, and at the round of the curve, it crossed the river and bridge. Today, the road swings around to the south, and then crosses a new bridge. the old road grade is still slightly easy to see on a sattlite map, but on the curve were the river is, there is no bridge.

Sadly, it is gone.
