Pennybacker Jr. Bridge in Austin, Tx

It’s more commonly known as the 360 bridge however was named after Percy Pennybacker Jr who was a pioneer in welded structure technology and designed bridges for the Texas Hwy Department in the early 1900s.

The Pennybacker Bridge was started in 1979 and completed in 1982. To help it blend in with the surrounding area it was designed with a weathered rust finish. Made of 600 short tons of steel produced in Japan and 3,400 short tons of concrete the Pennybacker Bridge cost $10M to design and construct.

The arched design was created to avoid having support columns because Lake Austin is very popular with water skiers, wake boarders, and boaters.
