1916 Pipeline/US-66 Bridge
This bridge still exists because it now carries a pipeline. You can see the pipeline come out of the hill on the far side.

1890,1947 US-66/Santa Fe
"Originally built for ATSF railroad use. In 1947, ATSF built a
new bridge for trains, this bridge was converted for highway use, and US Route 66 was rerouted from the Old Trails Arch Bridge to this bridge. In 1966, both US 66 and this bridge were replaced by Interstate 40. The bridge was not dismantled until 1978." [ArchievedBridgeHunter_1890]
Back from its railroad days.

Bridge Hunter calls the design a through cantilevered bridge. I wondered about that because the above images have a center pier. But note that there is no center pier in this image.

This is the only other image of the bridge that I saw that did not have the middle pier. So I guess the center pier was added after it was built. Was that part of the 1947 conversion to a highway bridge?

Pipeline Bridge with Triangular Towers
Note the "arms" that stick out from the base of the towers. They hold additional cables for lateral support.
Pipeline Bridge with Rectangular Towers
This bridge hangs the pipeline from two cables that curve inward to provide the lateral stability.
US-66 Route
I was surprised that US-66 crossed the Colorado River so farth south of Kingman, AZ, and Needles, CA. So I got these topo maps to study the route between those two cities. But they gave me another surprise. The bottom map (Needles Quadrant) shows US-66 going North from Topock and then east through the Black Mountains to Kingman. The top map (Kingman Quadrant) shows US-66 going South from Kingman along the Santa Fe, but then it stops when it reaches the Needles Quadrant! I've never seen a road discontinuity like that before in the topo maps.

A US-66 map shows that the Kingman Quadrant is wrong and that US-66 did go through the Black Mountains. I-40 followed the Santa Fe route instead of the US-66 route between Kingman and Topock.
