Thanks for catching this. I fixed it. I assume it was human error. I am using the jnlp version of JOSM. If you have any suggestions as to what I might have done wrong I would appreciate your input.

A waterway can have a weight limit when it is a culvert. A culvert is different from a bridge, it is a tunnel under a road. The weight limit, is the limit on the tunnel. A bridge is a free standing structure above the waterway. These changes were made based upon an authoritative dataset from Baltimore County, based on engineering definitions for bridges and culverts. Please see the map roulette link for further information.

OK, I understand what you mean now. Thanks, for catching that I didn't connect it to the parking lot line!

I have clarified that this path ends in a 3m fence at the private property boundary. It may be possible to continue along the fence, but the ground is rough and eroded. Clearly the fence is there to keep park users out of the surrounding neighborhood. I chose foot path because of the narrowness of the path (0.5m), but have set it to 'path' per your recommendation.
