Historic bridge survey update

Feb. 21, 2023, 2 p.m. CT

It's time to update TxDOT's historic bridge inventory. Join us to learn why TxDOT evaluates bridges for historical significance and how it surveys them: no small feat with more than 55,000 bridges across the state!

This webinar will focus on a specific type of bridge: non-truss bridges constructed before 1946. These bridges come in a variety of sizes, materials, and shapes, such as arches, beams, and slabs. They were a common choice in Texas from 1905 to 1955.

As part of the webinar, we'll discuss:

  • What are non-truss bridges?
  • How does TxDOT complete its historic bridge surveys?
  • What does TxDOT look for when surveying historic bridges?
  • How can you participate in this survey update of non-truss bridges?
