Horace Wilkinson Bridge

This bridge has a weird aspect to it.... all of the eastern approaches, on-ramps, and elevated roadways were of a steel stringer construction. But on the west side of the bridge, all of those approaches and on-ramps utilized the newer prestressed concrete girder technology. Makes me wonder if the western portion of the bridge (Port Allen side) was the last part of the bridge to be built.

The bridge is named after my grandfather Horace Wilkinson, Jr. and his son. Horace Wilkinson, III. My grandfather served in the Louisiana Legislature and my uncle served as a senator.

I drove to B.R. and back Friday. Sat on top of this bridge in rush hour traffic. To feel it flex and vibrate is awe-inspiring. Engineering marvel.
