Traffic ADVISORY – UPDATE on Daytime Work Zone Lane Restriction Planned on US 41 Twin Bridges at Henderson August 21-24

UPDATE on Daytime Work Zone Lane Restriction Planned on US 41 Twin Bridges at Henderson August 21-24

Due to a mechanical issue with the Under Bridge Inspection Vehicle (UBIV), the lane restriction planned for today on the Northbound lanes of the US 41 Twin Bridges has been postponed. There will be no northbound lane restriction today.

However, climbers are continuing their work on the superstructure of the northbound bridge without a lane restriction. Motorists should be alert for vehicles dropping off and picking up climbers and their equipment along the northbound bridge from time to time through the day.

The contractor will attempt to provide timely notice when the UBIV arrives and lane restrictions are required for it to be used to inspect the substructure of the bridge.

Updates as appropriate.


A contractor for the Kentucky Transportation Cabinet plans a daytime work zone lane restriction on the US 41 Twin Bridges between Henderson and Evansville, August 21-24, 2018.

This daytime work zone lane restriction is to allow use of a UBIV- Under Bridge Inspection Vehicle and other equipment to conduct a detailed inspection of the bridge structure. Climibers will also be used to expedite the bridge inspection process.

Initial inspection work will start on the northbound bridge with plans to restrict traffic to one lane on Tuesday & Wednesday, August 21 & 22. The inspection team expects to move to the southbound bridge with lane restrictions for southbound traffic on Thursday and Friday, August 23 & 24.

The work zone is expected to be on the bridge from approximately 8:45 a.m. to about 3:30 p.m., each weekday.

Motorists should be alert for slowing and merging traffic as they approach this work zone. The inspection team will be coordinating with the contractor on INDOT’s Fix for 41 Project just north of the US 41 Twin Bridges. Whenever possible, the inspection team will try to shorten the length of the work zone to improve traffic flow.

Motorists should use appropriate caution where equipment, flaggers, and inspection personnel are along the roadway in close proximity to traffic flow.

All Kentucky bridges get a detailed inspection every two years, with long-span lake and river bridges getting an annual wall-through inspection.

The US 41 Twin Bridges, also known as the Bi-State Viet Nam Gold Star Memorial Bridges, are located at US 41 mile point 19.649 in Henderson County about a mile south of the Kentucky-Indiana State Line. They carry approximately 40,000 vehicles per day across the Ohio River between Henderson, KY, and Evansville, IN.

The bridges are located at Ohio River navigation milepoint 786.8, about a mile downstream from the confluence of the Green River and the Ohio River.

The northbound bridge was opened to traffic on July 4, 1932. The southbound bridge was opened to traffic on December 16, 1965.

The Twin Bridges have a total length of 5,393.6 ft. with a 720 ft. main navigation span. The bridge superstructure is a Warren cantilevered through-truss design.

The Kentucky Transportation Cabinet (KYTC) and Indiana Department of Transportation (INDOT) have a joint 3-year rehabilitation project along the US 41 Corridor between the US 41 Twin Bridges and the I-69 Interchange at the south edge of Evansville. This joint project included a deck overlay on the southbound bridge. For more information on Fix for 41 go to:

Kentucky and Indiana also have a joint plan to construct a new bridge to carry Interstate 69 across the Ohio River near the US 41 Twin Bridges. For more information on that project go to
