The signs were unveiled as part of the renovated Rankin Bridge, which leads to Duquesne among other places just east of the city. But the town's name is misspelled D-U-Q-U-E-N-S-E instead of D-U-Q-U-E-S-N-E.
Duquesne was the name of a pre-Revolutionary War governor-general for whom Fort Duquesne was named. The historical moniker also labels a bridge, a beer, an electric company, and a former sports arena in the area, to name just a few.
Still, the Pittsburgh Post-Gazette says the name is commonly misspelled. A reporter who typed in the misspelled name into the Google search engine still got 25,000 hits.
