Spectators watch as explosive demolition charges on the eastern portion of the old Champ Clark Bridge are set off to drop the steel trusses of the bridge into the Mississippi River in Louisiana, Mo., on Monday, Nov. 18, 2019. The old Champ Clark Bridge was opened in 1928 to carry traffic along U.S. Route 54 over the Mississippi River. The new Champ Clark Bridge, pictured to the right, opened to the public on Aug. 3, 2019. This western part of the old bridge was demolished on in October. Crews will now use cranes to clear the debris out of the water and heavy equipment to tear down the bridge piers.
