Los Angeles Sixth Street Bridge and Texas Seventh Street Bridge Similarities - Mary Cummins real estate appraiser

After I posted about the new Los Angeles Sixth Street Bridge and viaduct a Texas friend told me it looked like the Fort Worth, Texas Seventh Street Bridge and viaduct. They look very similar. Some facts about both. 

The Los Angeles, California Sixth Street Bridge and Viaduct built 2022 is 3,500 ft long with 20 arches and four traffic lanes. It took six years at a cost of $588,000,000. It replaced the 1930 Sixth Street Bridge and Viaduct.

The Forth Worth, Texas Seventh Street Bridge and Viaduct built 2013 is 1,000 ft long with 12 arches and four traffic lanes. It took four months to build at a cost of $25,000,000. It replaced the 1919, 1954 Van Zandt Viaduct.

Arches are actually a common bridge element. Early bridges back before Roman times were arched for structural integrity. Here's an article on only arched bridges.

The original Sixth Street Bridge built in 1930 below had arches but only two. The LA bridge has arches that go below the bridge driving surface whereas the Texas one does not. Still, they are very, very similar bridges. I think at the very least the LA bridge was inspired by the Texas bridge.
