About this project
MnDOT is planning a resurfacing project for Hwy 4, from Hwy 212 in Hector to Hwy 19 in Fairfax. The primary goal of this project is to improve the safety and pavement conditions of the highway. Additionally, several culverts along the route will be repaired and replaced as part of the project to enhance infrastructure and ensure long-term durability.
Schedule Update
Originally planned for 2027, the Hwy 4 resurfacing project has been moved up one year and will now be constructed in 2026.
Traffic impacts
During construction, the detour route will include Hwy 212, CR 16, and Hwy 19 and is expected to last the full construction season.
Project Update: May 15, 2026
- Crews continued grinding off the old pavement and began mixing the remaining material to rebuild the base of the road
- Next week, crews will continue removing old pavement and begin installing edge drains
- edge drains are small underground pipes along the edge of the road that help pull water away from the pavement to prevent damage
