Bob:
The Castleton-On-Hudson Bridge (the correct name) is part of the N.Y.S. Throughway system, which has no weight restricted bridges. If you were to pull out of the G.E. dock with a 300-Ton transformer, you'd have a problem. But standard tractor-trailer loads are well within the bridge's capacity. Note that tandems are limited to 2 trailers in N.Y.S., not 3 as in some other states.

What is the maximum weight allowed over the bridge with tractor trailers?
