Mexico's Bridges: Viaduct Beltran (3)

A closer look at the pier walls under the middle of the Viaduct Beltran. Yesterday's photo was taken on a hill that hid the bottom of these piers, but in this photo we can see their full height and also that they are flared at the bottom.

The abutments are socketed into the canyon walls and there is a very tall pier in front of the south abutment. The bottom of this tall pier is hidden in a ravine. 

In this photo, we get a good view of the haunched and foreshortened superstructure and of the shear key at the top of the pier. This is the first of several long, tall bridges as we travel north on Route 54D through southwestern Mexico.
