MoDot says Area travelers will begin to see activity as preparations are in place for preliminary work to begin on a bridge replacement project located on Missouri Route 79, over Bear Creek, Norfolk Southern Railroad and Warren Barrett Drive, 0.4 miles north of Route T in Hannibal in Marion County. Weather permitting, work will begin on November 15, including surveying, clearing and grubbing, the construction of a work pad and foundation inspection holes for the drilled shafts. While preliminary work will have no impacts to traffic, the closure of the Sodalis Nature Trail, within the project limits, will be necessary until the project is completed next Fall. Substantial work on the bridge replacement will begin later this year or early 2024.
