Highway 25 Closed Between Monticello and Buffalo as Yearlong Construction Project Begins

After years of discussion and planning, one of the biggest State Highway projects in Wright County is finally underway. Construction crews and the Minnesota Department of Transportation have closed Highway 25 between Monticello and Buffalo – as of April 21 – as a full season of reconstruction and redesign of one of the county’s main thoroughfares gets underway.

Here’s a timeline of the project:

Mid-April through July: Update, repair infrastructure and construct new access

Includes: underground drainage pipes, roundabouts, turn-lanes, intersection lighting, guardrails, access approaches

• Hwy 25 detour Monticello to Buffalo (PNG): Road closed Cameron Ave. NE (Co. Rd. 131) to John Ause Memorial Dr. to complete roadwork. Detour via Cameron Ave. NE (Co. Rd. 131), Co. Rd. 37 NE, Co. Rd. 12 and Hwy 55 Buffalo. Google map
• Local access: Hwy 25 will be maintained to those who live, work or visit those within the closed work zone; however, hard closures will be necessary at times to work under the road. Enter/exit nearest your destination, use alternate entrances or side streets.
  • Watch for access changes at these locations:
    • Wright Co. Rd. 37 at Hwy 25 to construct a roundabout. Google map
    • Catlin St. at Hwy 25 to construct a roundabout.
  • Hospital/ER access in Buffalo: Will be open and maintained at all times using side streets from Hwy 55 or Hwy 25, follow blue colored H hospital signs.
    • • Contractor will communicate directly with emergency services on any updates

July through Fall 2026: Reconstruct the road surface
