The Kansas Department Of Transportation is replacing the Deer Creek Bridge on US 166 or West Main Street just outside Sedan. This affects mainly north and southbound HWY 99 traffic and traffic on business US166 west of Sedan. There will be detour signs rerouting southbound HWY 99 traffic west to US 166 business loop and then back east on US 166 to the HWY 99 intersection south of Sedan. Northbound HWY 99, at the intersection south of Sedan, will go west on US166 to the Business US166 west exit following it east to HWY 99 west of Sedan.

KDOT say work on the 1.2 million dollar project, weather permitting, should be completed in the spring of 2023.
