1908 Photo of the Arch of Welcome in Denver Colorado near 17th Street.
Set in front of the station at the hub of 17th Street, the arch originally featured the word “WELCOME” on both sides. ... The arch didn't quite make it through Speer's “ages.” Cars got bigger, downtown busier, and in 1931, the structure, a bit dilapidated, was deemed a traffic hazard and torn down.
