A project to replace a bridge on U.S. 166 over the Arkansas River is scheduled to begin Nov. 28. KDOT originally anticipated starting this project in January, but the contractor has moved up the schedule.
The bridge is about five miles east of the Cowley/Sumner county line. The $6,368,390 project has a 250 working-day schedule. A.M. Cohron & Son Inc. of Atlantic, Iowa, which has an office in Emporia, is the prime contractor for the project.
This construction project will have a major impact on traffic in both Sumner and Cowley Counties.  Highway 166 provides a high-profile connecting route between the two counties.  
The state detour will follow Highway 77 and then travel Highway 160 through Winfield.  It then will go west to Wellington, south to Highway 81 near South Haven,  and then over to Highway 166.
The bridge was built in 1937 by the Kansas State Highway Agency.  Its last inspection was in August of 2016, and was judged to be in fair condition.  
The inspection also found “that the river bank was beginning to slump. River control devices and embankment protection have widespread minor damage. There is minor stream bed movement evident. Debris is restricting the channel slightly.”
