Reconstruction of County State Aid Highway (CSAH) 4 (Valleyhigh Road NW) between CSAH 5 and County Road (CR) 158 will be moving into Phase 2 on October 4, 2021

ROCHESTER, Minn. – Hoffman Construction is the prime contractor for the $9,800,000 project, which includes grading, concrete surfacing, and realignment of CR 105 going into Oxbow Park. Construction is anticipated to be complete by August 12, 2022. Grading, culvert work and aggregate surfacing will be completed by mid-November, 2021 with concrete paving taking place in Spring of 2022.

The initial phase of construction for the project has been completed.  Work will now move into the second phase, where CSAH 4 (Valleyhigh Rd NW) will be closed from CSAH 5 to CR 158 with the intersection of CSAH 3 / CR 103 open for cross traffic, and CR 105 will also be closed from CSAH 4 to south of Oxbow Park. A signed detour for Oxbow Park traffic will be posted during this phase.

Phase 2 includes an official detour being placed as shown below in the Detour Map. Access to CR 105 and Oxbow Park will be from CSAH 3 / CR 103.

Motorists should expect delays and seek alternative routes.
