I dig the infinity symbol portals.

This beautiful bridge will be restored...look for construction to begin within next several months. As for the date of construction, unfortunately documentation of these bridges is difficult. Best information(based on similar construction) indicates the truss was built sometime between about 1890-1910. Since these bridges were usually purchased by the county, the records for actual date of construction would be found there.

Sufficiency rating is a complex equation that takes into account a bunch of things including roadway alignment, roadway width. Actual bridge condition is only one factor. One of the most pointless parts of the equation is that a metal truss bridge is automatically deducted points for being a metal truss bridge, because they are fracture critical. I say this is pointless because a fracture critical bridge is perfectly safe and sufficient if maintained correctly.

This bridge is an example of why I can't understand bridge ratings. Satisfactory, fair, fair = structurally deficient? Fifty cars a day and it gets 16.5 sufficiency rating? What is 'sufficient' for 50 crossings a day? I wonder, about so many things...

Hey Tom, I am having trouble in the Project Tracker at TxDOT identifying this bridge as a project. I also am looking for a couple of others that I was told about. Can you help. Julie

Glad to hear this news as this is a beautiful bridge. I hope they research it as part of the rehabilitation, as I'm positive they will find it to be much older than what is listed.

Major refurbishment is planned.

This bridge has some beautiful portal details. I question the 1910 date listed, as this span looks more akin to a ca. 1890 span.
