Angeles Crest Highway over Slide Canyon
Posted August 9, 2008, by Thomas Morgan (morgantm [at] netzero [dot] com)

My father's company, T. M. Morgan Paving Co., was the general contractor on this section of the highway. I believe the bridge was subcontracted to one of his nephews, E. Thomas.

I have a reduced copy of the original plans for the highway and the bridge.

I also have an album of photographs taken by a professional photographer and sold to people attending the opening of the highway.

Slide Canyon Bridge
Posted November 29, 2007, by David Kimbrough (kimbrough-photo [at] charter [dot] net)

This is a rather short bridge but only because slide canyon is not very wide. It is not really even a canyon, more like a big scar on the side of the mountatin. It drops down at something like 45o. The side of the mountain is pretty step any way but that cut makes it impassible without this bridge.
