High School STEM Students will Help Dedicate The Interpretive Panel They Designed
HANNIBAL - In 2017, just as construction began on a new Champ Clark Bridge, area high school STEM (Science, Technology, Engineering, Mathematics) students were invited to provide a design concept for an interpretive panel that would include pieces of the old, historic bridge and serve as a monument overlooking the new bridge. Construction of the interpretive panel was in the contract with Massman Construction to mitigate the removal of a historic bridge on the state system. Hannibal High School was the winner of five teams from four schools who participated, with Pittsfield High School supplying the wording featured on the top of the panel.
The interpretive panel is complete and installed in Riverview Park in Louisiana, Mo., and Massman Construction and the Missouri Department of Transportation would like to invite area residents to help dedicate the unique structure during a short ceremony at the park on Wednesday, Jan. 15 at 1:30 p.m. “We expect this to be the final event celebrating both the historic and new bridge, and we appreciate all the support we have received over the last several years throughout the project,” said MoDOT Champ Clark Bridge Project Director Keith Killen.
The program includes recognition of both high schools, a brief history, remarks from elected officials, and the dedication of the structure. The event is expected to conclude by 2 p.m. Photos of the ceremony and the structure will be posted on www.champclarkbridge.com.
MACON – Demolition continues on the old Champ Clark Bridge in Louisiana. The first implosion to demolish two spans of the old bridge took place in October. Since then span 1 over the railroad tracks has been removed. Now plans are in place for the second implosion to drop the remaining two truss spans, #4 & #5, on the Illinois side.
This pair of truss spans is scheduled to be dropped into the Mississippi River Monday, Nov. 18 between 9:00 a.m. and 12:00 p.m. “As we experienced with the first demolition event, the timing of the blast can be delayed. Massman Construction will do its best to have the blast occur within the scheduled window of time. However, ensuring the safety of everyone involved is their number one priority, so a delay may be possible,” stated Missouri Department of Transportation Project Director Keith Killen.
HANNIBAL – The next step in the removal of the old Champ Clark Bridge is to begin dismantling the first span over the railroad tracks on the Missouri side. “We are awaiting all the necessary approvals to implode the Illinois side spans, and in order to keep progressing with the removal, we will work on this span next,” explained Missouri Department of Transportation Project Director Keith Killen. The work is scheduled for Tuesday, November 5, Wednesday, November 6 and Monday, November 11, weather permitting.
The truss of the bridge span will be removed in segments. “Our contractor will cut sections of the old bridge, then use a barge mounted crane to place the sections on a barge,” Killen explained. The lane restrictions are necessary to allow crews to access the cut points on the old truss.
“There are three segments being removed that will require the lane restrictions, but when we get to the final segment, we will actually have to stop traffic for up to an hour because of the size of the segment,” Killen noted. He added that because the size of that segment, it is safest for the traveling public to not be on the new bridge. The one-hour closure is tentatively scheduled for Monday, November 11, a time is to be determined.
Killen stressed the work could be delayed due to weather, especially wind. Updates will be provided as work progresses.
Information will be distsributed as soon as the date is known for the demolition of the last two spans.
HANNIBAL – Massman Construction and the Champ Clark Bridge Team invite the public to the monthly update meeting being held Saturday, October 26 at 10:00 a.m. in Riverview Park in Louisiana, weather permitting. This is an informal meeting and attendees are encouraged to ask questions. The update usually lasts about 60 minutes.
This is a 5 minute video showing the first blast involving two spans of the old Champ Clark Bridge. This occurred approximately 4:25 p.m. The blast was recorded LIVE on Facebook and is now available on YouTube at https://youtu.be/q_MnwYSV2BY.
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.
HANNIBAL – With the new Champ Clark Bridge now open to traffic on August 3 on U.S. Route 54 over the Mississippi River, demolition of the historic, 1928 bridge was inevitable. While Massman Construction Company has been full speed ahead with deck removal of the old bridge, a more audible and visible phase of the demolition will include blasts. The first pair of truss spans is expected to be dropped into the Mississippi Friday, October 18 at approximately 9 a.m., with the second pair to follow approximately two weeks later. “We have a good idea of when the blasts will occur; however, these are not typically a set time but rather a window, as many details need to be carried out and the situation must be perfect to ensure safety,” stated Missouri Department of Transportation Project Director Keith Killen. While 9 a.m. is the planned blast time, a lot of preparation has to occur to ensure everyone’s safety, so it could be delayed.
The first blasts will be on the Missouri side. “Massman will have people stationed around the perimeter of the safe area to keep people from encroaching in the safe area,” Killen said. Unfortunately, most of the Missouri side of the riverfront is included in this safe area. “We will work with the City of Louisiana to set up signs and traffic control to limit where onlookers can safely watch the blasts,” Killen added. The demolition blasts will be available to view live on the MoDOT Northeast District Facebook page.
Once truss spans 2 and 3 on the Missouri side have been dropped, Massman will have a limited time frame to retrieve all debris from the Mississippi River in order to safely re-open the river to commercial barge and private boat traffic. The new bridge will temporarily close, possibly up to 45 minutes, as a safety precaution during each blast.
The next phase will include dropping truss spans 4 and 5 on the Illinois side, leaving the final span over the railroad to be dismantled later. This will also be available to view live on the MoDOT Northeast District Facebook page.
Work will then begin on the removal of the piers above the water level. “This phase will not utilize explosive blasting,” said Killen. “Massman has chosen to jackhammer the existing piers to prevent possible damage to the new bridge,” Killen added.
After the removal of the above-surface piers has been accomplished, work will move below the water surface. “The remaining pier sections will be strategically drilled in order to allow for the placement of explosives prior to blasting,” Killen explained. He noted blasting of the piers would not be as dramatic as detonation of the truss spans. All resulting debris will be removed from the river bed including any debris larger than about the size of a football.
