Hwy 25 Buffalo to Monticello:
2026 construction
 Progress update
Multiple crews have been hard at work along Hwy 25 between Buffalo and Monticello. The project remains on schedule.
Local traffic will encounter some changes on Monday, June 1, between Anderson and Co. Rd. 83 as workers shift work zone to begin construction on the west (southbound Hwy 25) side. Watch for crews, equipment and expect changes all day into the night on Monday.
 Crews have completed concrete curb and truck apron at Co. Rd. 37.
Co. Rd. 37 roundabout
Crews have been working on the Co. Rd. 37 roundabout to get it open by June 2. They've been completing concrete work—center truck apron, curb, gutter and walk/road approaches. Paving the asphalt lanes are scheduled for May 29-June 1.
Crews will pave the roundabout at Co. Rd. 37 and then use it for the Hwy 25 detour for the rest of the project.
The future paved trail will remain closed until other trail segments are ready to be paved.
Detour changes on north end Tue, June 2
The Hwy 25 closure and detour will extend northward from John Ause Memorial Dr. to Co. Rd. 106 (85th St. NE). Through travelers will continue on Hwy 55 in Buffalo, Co. Rd 12, Co. Rd. 37 NE through the new roundabout, then use Co. Rd. 117 (Edmonson Ave. NE) and School Blvd. back to Hwy 25 in Monticello.
Remember it takes time to set up the detour route. Expect changes the first few days as signs and barricades get adjusted.
Detour map
Local access will remain open for those who live, work or visit locations within the work zone. Short-term hard closures will occur as crews work under the roadway. Use the closest possible entrance to your destination and follow posted signs; alternate routes may be needed.
It will take some time for everyone to get used to the upcoming changes. Please be patient and stay on the signed detour and avoid closed off areas. Residents along the corridor continue to see increased traffic and turn-arounds on dead-end roads, so your cooperation is appreciated. :)
Roundabout construction schedule:
- April 21-June 1: Hwy 25 and Co. Rd. 37
- May 4-mid-July: Hwy 25 and Catlin St.
- After July 1: Hwy 25 and Co. Rd. 113
All information is tentative and subject to change. Weather, contractor schedules and material delays are examples.
Crews complete concrete work at the Co. Rd. 37 roundabout
Deep underground structure work with use of a trench box the week of May 18.
More about this project
This $11.4 million project will rebuild Hwy 25 between Catlin St. and north of Davidson Ave., repair drainage and improve access at several locations. Crews will also build new roundabouts at Hwy 25 and Co. Rd. 37 and at Catlin St., with Wright County constructing the Co. Rd. 113 roundabout later in summer 2026.
