HANNIBAL - The Missouri Department of Transportation has the final results of the Champ Clark Bridge inspection, and, to no surprise, the bridge will have to be closed while repairs are being made. "More than 1500 rivets will need to be replaced on the underside of the Champ Clark Bridge," said MoDOT Area Engineer Brian Haeffner. "These rivets are part of the original bridge built in 1928, so they are rusty and will require a significant amount of time to manually remove," he added. These rivets will be replaced with new bolts.
"This project will take several weeks to complete, yet we only need to close the bridge while crews make the rivet replacements during the day," Haeffner explained. In addition to this work, maintenance crews will be doing some other routine work including flushing and striping the bridge.
The bridge will be closed the following times, weather permitting:
Monday, October 19 through Wednesday, October 21 from 6 a.m. until 6 p.m.,
Thursday, October 22 from 6 a.m. until 4 p.m.
Monday, October 26 through October 28 from 6 a.m. until 6 p.m.
Thursday, October 29 from 6 a.m. until 4 p.m.
"It is anticipated the bridge will have to be closed into late November, but the schedules will not be definite until we see how work is progressing," Haeffner explained. "We will keep everyone informed as to if, or when, we need to continue closing it for the repairs," Haeffner promised.
Haeffner added MoDOT was glad the load posting didn't change after the inspection, so it will remain at a 40 ton weight limit.
Because the bridge is nearly 90 years old, it took MoDOT some time to determine the safest and most economical way to replace these rivets.
MoDOT engineers and technicians will be using hydroplatforms (see picture) to perform the work underneath the bridge.
