it has two hinged sides that roll open. it's a bascule bridge
when closed, there is approx. 75 feet of clearance for boats. when open, there is about 140 feet.
here is the entire bridge now! you can see the draw bridge in the center when it turns to a metal span instead of concrete on the freeway. when a large ship comes through, it will roll open. as you can see, there are some small and medium sized ships coming in and out of the canal (ships from 3d warehouse).
the city has opened the entire bridge system to the public. now people from the suburbs can get to the downtown faster so better things will happen now.
in a way, it's a bridge within a bridge within a bridge
. the freeway is like one super long bridge then there's the Ekana Bridge (the cantilever) and then the draw bridge.
oh and don't for get the Adams-Onis Bridge that goes to beachside! lots of bridges!
more soon, and a building boom is underway!
