SH-22 reopens, US-377/SH-99 closes in Tishomingo beginning Monday; new detour route in place

Friday, April 16, 2021

This project is weather permitting:


Drivers can expect the following traffic changes on SH-22 and US-377/SH-99 in Tishomingo beginning Monday, April 19:

  • East and westbound SH-22/Main St. will reopen at the Pennington Creek bridge, meaning that SH-22 and US-377/SH-99 traffic (runs east and west) will be able to cross the bridge through Tishomingo.
  • North and southbound US-377/SH-99/Kemp Ave. will be closed between the SH-22 East/Main St. junction and Sixth St. through May for pavement reconstruction.
  • All north and southbound US-377/SH-99/Kemp Ave. traffic will be detoured around the closure locally on SH-22/Main St., Chisholm Ave. and Sixth St. in partnership with the City of Tishomingo. These are the only city streets permitted for use as a temporary highway detour.


Drivers can expect congestion and delays and should plan extra travel time.

The nearly $7 million contract for this work was awarded by the Oklahoma Transportation Commission to C3 Construction of Ada. The project also includes sidewalk reconstruction and traffic signal replacement and continues through spring 2021. The Chickasaw Nation is partnering with ODOT to provide a portion of the funding for this project.
