Missouri Gov. Jay Nixon has issued a proclamation honoring the 50th anniversary of the completion of the Gateway Arch.
The final piece of the 630-foot-tall Arch was put into place on Oct. 28, 1965. Events in St. Louis on Wednesday are marking the anniversary.
Nixon, in a statement, says the Arch made the St. Louis skyline instantly recognizable around the world. He noted that millions of people visit the monument each year.
Other events Wednesday include a morning Missouri History Museum remembrance by sheet-metal and iron workers, electricians and engineers who helped erect the wicket-shaped landmark along the Mississippi River's western bank that's the nation's tallest man-made monument.
