Current Construction

Updated Friday,  August 21, 2026

• • Construction on U.S. Highway 385 from Pactola Dam to Calumet Road is substantially complete, and the placement of final surfacing is expected to be completed in the summer of 2027.
  • Seeding and permanent erosion control operations will continue through the end of August 2026.
  • The driving surface within the construction area is oiled blotter (a hard, packed surface that resembles asphalt) with pavement markings. This surface may feel slick, so drivers are encouraged to be cautious and allow additional stopping time, especially in wet conditions.

  Bi-weekly updates will be paused until surfacing takes place in the summer of 2027.
