Lit on June 6, 1929, the Rock Springs Coal "Welcome" sign spanned the Lincoln Highway about 100 feet from the Union Pacific Railroad main line. Reportedly the largest arch neon sign erected in the Rocky Mountain West, it was visible from passenger and Pullman car windows and was the first sign erected to advertise coal, the industry on which local citizens depended for their livelihood. After the Lincoln Highway was relocated, the sign was moved nearer the log cabin Chamber of Commerce building on Bridger Avenue, where it remained until Western Wyoming Community College refurbished it, changed its colors, and erected it over the college entryway. It was later dismantled and nearly destroyed, but in 1994 the Rock Springs Historical Museum Board, with assisted funding from the Wyoming Centennial Committee, restored it to its earlier grandeur and returned it near its original site at Railroad Park. On September 7, 1997, former Governor Mike Sullivan rededicated it and recalled that the welcome and progress associated with the sign's beginnings in 1928 continued in Rock Springs and Sweetwater County.
