Great Bridge

So, how to you make a bascule bridge with NO hinges.  Easy right?


We had just crossed the walk way on the bridge when the whistle sounded for traffic to pass.  I quick got my phone in time lapse mode to capture the moment.

The bridge swings on a geared arch with the concrete counter weight hanging above the traffic.  The weight swings down to within just a foot or two of the roadway surface.  The next morning we opened the bridge to get to the Great Bridge locks.
