If you go left right there after the bridge, isn't that river road with the river on your left? Also, after a hard rain, be careful, that road floods out in blind spots and it takes them a couple days go get signs up. I remember one time my girlfriend and I were going up that road (she lived in Radnor) and we had to slam on the brakes, we came inches from a 12' water road block. It was very odd to see the water that high.
