AX1046 Columbus BM -- Columbus TX - U.S. Benchmarks on Waymarking.com

This benchmark was placed by the CGS in the 1940s at the western abutment of the then-Southern Pacific railroad bridge east of Columbus TX.

For purposes of a visit to this benchmark, we will accept a photo of the abutment taken from the bank of the Colorado River. Within 10 minutes after we got off the bridge, a train roared by at track speed -- 50 mph.
