Description
"In his 1937 application for registration to practice professional engineering in Texas, George G. Wickline, who had been a bridge engineer for the City of Dallas until September 1916, states that in that month he began working as a bridge engineer for the County of Dallas. He also claims credit for the design, and supervision of construction, for a "Commerce Street Viaduct." (**) It is likely that the replacement of the old steel spans by a new concrete bridge took place sometime in 1916, and that George Wickline was the designer of the new bridge and any new approaches built at that time."
(**) Wickline, George G., "Application For Registration To Practice Professional Engineering," 1937, on file at Texas State Board of Registration for Professional Engineers, Austin, Texas. In 1918, Wickline became the first state bridge engineer for the Texas Highway Department
