Description 

All six of the bridges are posted for a 40 ton weight limit.

These are all six identical low water crossings of the Ledges State Park. These bridges where built in 1941 to provide a way to cross the creek, but to not really impede water flow. So the water on these "bridges" actually flows over the slab instead of underneath it.
