MoDOT to begin bridge repair project in Shell Knob

Wednesday, August 29, 2012

The Missouri Department of Transportation (MoDOT) has announced that crews will begin major repairs on the Highway 39 bridge over Table Rock Lake in Shell Knob during the week of Sept. 4.

The bridge deck will be replaced one-half at a time to allow one lane of traffic to continue across the bridge. In addition to replacing the deteriorating bridge deck, contractor crews will add new bridge walls and paint steel parts of the bridge.

Throughout the course of the repair work, drivers can expect one-lane traffic and narrowed driving lanes. The repair project is expected to take around nine months and scheduled for completion by May 24, 2013.

During the week of Sept. 4, crews will begin installing a containment system underneath the bridge to keep debris from falling into the lake and barrier along the center of the bridge. Flaggers will direct traffic when crews are working.

As the containment system is installed under the bridge, a boat will be in the water directing boat traffic away from the immediate work areas. Once the containment system installation is complete, boating traffic under the bridge should not be impacted.

Temporary traffic signals will be installed at each end of the bridge to regulate one-lane traffic across the bridge around the clock beginning during the week of Sept. 10. Drivers can expect up to a 20 minute delay when waiting to cross the bridge. However, normal wait times will be less than five minutes.

The open driving lane across the bridge will be narrowed to nine feet. Electronic message signs will be placed on Highway 39 near the intersection of Highway 39 and Highway 76/86 advising drivers of the narrowed lane on the bridge.

Drivers pulling boats and campers are encouraged to find alternate routes. Over-sized loads will also be directed to use other routes to cross Table Rock Lake.

Construction crews will work with emergency responders to get them across the bridge quickly during emergencies.

The four observation parking lots at the corners of the bridge are within the work zone and will be closed throughout construction.

Phillips Grading and Construction, of Boonville, is serving as the prime contractor for the repair project. The company submitted the low bid amount of $5.4 million.
