Hwy 25 — Buffalo to Monticello

Hwy 25 between Cameron Ave. NE and John Ause Memorial Dr.

Access 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, reconstruct entrances and construct roundabouts.

Tips

• Enter/exit nearest your destination, use alternate entrances or side streets
• Allow for extra time in case of delays
• Share with visitors what the best route is to take before they head out
• Watch for sudden stops and flaggers controlling one-way traffic
• Expect gravel or grooved road surfaces, no shoulders
• Visit 511mn.org to see current travel speeds and impacts
• Sign up for project email updates

• Wright County to construct a roundabout at Hwy 25 and Co. Rd. 113 from July to late fall 2026
• Install pedestrian access improvements, includes trail and all new roundabouts

This project will rebuild and recycle the existing road surface using a process called Stabilized Full Depth Reclamation (SFDR).

How it works

1. Break it down: Machines grind up the old asphalt and some of the gravel underneath.
2. Strengthen it: Special materials like cement or asphalt emulsion are mixed in to make the recycled base stronger.
3. Pack it tight: The new mix is compacted to form a solid, durable foundation for the road.
4. Resurface: A new layer of asphalt is paved over the surface.

Benefits

This process saves money, protects the environment by reducing waste and truck traffic, and creates stronger, more durable roads by reusing the existing surface.
