The Champ Clark Bridge, built in 1928, is part of the U.S. Route 54 corridor and spans the Mississippi River connecting Louisiana, Missouri with the state of Illinois.

HANNIBAL - Due to high winds over the last few days creating unsafe working conditions to prepare for the historic Champ Clark Bridge demolition, the time for the first blast has been move to a window between 11 a.m. and 1 p.m. on Friday, October 18.

The two truss spans on the Missouri side will be imploded first; a few weeks later, the two truss spans on the Illinois side will be imploded with a blast.  “There is a lot of interest from residents, schools and media within the region, and because the safety perimeter encompasses a lot of viewing areas in Louisiana along the river, we are encouraging viewers to park away from Highways 54 and 79 and walk to some of the safe areas,” explained Missouri Department of Transportation Project Director Keith Killen.

Two areas that are available for viewing include the Louisiana riverfront on the south side of the bridge, near the Massman Construction project offices on Water Street and at the south end of Riverview Park.  Another safe way to watch is to view it on MoDOT’s Northeast District Facebook page, as the blast will be featured as a live video on the social media platform.

Massman Construction Co. will have personnel manning the perimeter of the safe zone and will be able to direct viewers to safe areas, and there are some streets that will be closed prior to and immediately following the blast.  These include Edison Avenue, Jackson and Main, and Noyes.

The new bridge will close approximately 45 minutes prior to the blast and could remain closed up to 45 minutes after the blast.

“We appreciate all those interested in viewing the blast be respectful of the safe zone,” Killen said.  Having viewers in an unsafe area is what could delay the blast.  “We plan to have the blast sometime between 11 a.m. and 1 p.m., yet there is a lot of preparation that goes into it, so it could be delayed for various reasons,” he added.  A series of airhorn blasts will occur approximately a few minutes prior to the implosion.

A video of the implosion will be posted on MoDOT's YouTube channel later that afternoon, along with a link to it posted on the www.champclarkbridge.com site.
