D3 - Hwy 25 Buffalo to Monticello: 2026 construction
 We’re ready to dig in!
 Crews quickly prepared the work zone the week of April 13. Storm drainage, surveying and widening for temporary access along Hwy 25.
Road closes, detour starts Tue, April 21
Hwy 25 detour between Cameron Ave. NE south of Monticello and Hwy 55 in Buffalo
Through early July
Hwy 25 will close between John Ause Memorial Dr. in Buffalo and Cameron Ave. NE south of Monticello. A signed detour (above map) will take you along Cameron Ave. NE (Co. Rd. 131), Co. Rd. 37 NE, Co. Rd. 12 and Hwy 55 in Buffalo.
Local access will remain open for those who live, work or visit destinations within the work zone. However, temporary hard closures will be needed at times as crews work beneath the roadway. Enter and exit as close to your destination as possible and follow posted signs. Alternate entrances or side streets may be required.

April 21 – early June: Hwy 25 and Co. Rd. 37
