Description 

If you look closely, the piers are built with stone on the north side and concrete on the south side.

The entire bridge (east side too) is a concrete arch bridge, but thanks to a stone facade it looks like a stone arch bridge. The stone facade was chosen for this bridge not only for aesthetic reasons, but also because the stone would protect the concrete superstructure in the event of a flood that might carry ice and other heavy debris.
