Historically US 80 connected Dallas and Ft. Worth. Although US 80 was decommissioned along that segment in 1993, some evidence of US 80's historical presence in Ft. Worth survived for nearly another three decades. This photo was taken looking north on Beach Street:
Even though the designation of Lancaster Avenue was changed to TX 180 in 1993, overhead signage still had not been replaced (most likely related to the fact that Beach is not maintained by TXDoT). The sign on southbound Beach had weathered the elements much better than its northbound counterpart:
Those sign panels were finally replaced in 2020 (presumably by the City of Ft. Worth, not TXDoT). Although I have no proof, I suspect the new panels were in-kind replacements, i.e. they were originally created with US 80 shields. By March 2021 the panels referred to US 180 (instead of US 80), but close inspection reveals that the US 180 shields appear to be patch-overs:
The other irony here is that this segment of Lancaster did indeed carry US 180 from 1949-1979 (it was overlapped with US 80 during that timeframe). But since 1993, Lancaster has been neither US 80 nor US 180. It is actually TX 180 now, but so far neither of these overhead signs on Beach have ever correctly referenced that designation.
