LOWER MISSISSIPPI RIVER - ILLINOIS RIVER
General / Bridges / Construction
Hardin Drawbridge; Continuing through February 2027, construction work to repair or replace the bridge fender system and pile clusters will be conducted. Work will be conducted during daylight hours, Monday through Friday. Continuing until November 13, 2026, a pile-driving template will be temporarily positioned along the downstream side of the bridge on the right descending bank, encroaching up to 15 feet into the channel. The template will be lighted at night. During active work hours, the horizontal navigational clearance through the bridge span will be reduced to 200 feet and restored to normal clearance at night. Mariners are requested to contact M/V SAM B., via VHF-FM Channel 16 one-hour before arrival at the bridge to arrange passage. All vessels should exercise caution while transiting the bridge and report any unsafe conditions to the U.S. Coast Guard.
