Is this a railroad or a wagon bridge at Colbert's bridge across the Red River?

The "Willis Bridge" now connects Oklahoma to Texas over Lake Texoma along US 377.

In 1931, the toll bridge at the former Sacra's Ferry site across from Brown Springs closed for good in favor of a free bridge a upstream.

Colbert's hotel stood above his ferry, which once was replaced by a bridge in 1875 that the Red River promptly washed away.
