Mile 48.2 - The original bridge pivoted to allow clearance for passing boats. Now, the bridge is access from the town of Point of Rocks to the parking and fishing. It's only a single lane and doesn't look that sturdy, but it's safe to drive over and provides access to fishing, parking and the boat ramp.
At the end of this path, across from the pivot bridge, you can see
what used to be the home of the Shore Sisters. They had a lifetime lease on
the property which fell into the hands of the NPS when the park was first created.
When the lease came due (with the death of the Shore sisters), the bulldozers came and another historic home fell to the wrecking crew. NPS seems eager to return the canal to it's 19th century appearance as there are a lot of other more recent structures they bulldozed over, not just the Shore sisters home.
