Hwy 4 Reconstruction

St. James

Traffic impacts

A construction sequencing map of the Hwy 4 project.
  • A short and brief detour on the 7th Street section of Highway 4 in St. James will be needed beginning Monday, September 17 as a few concrete panel replacements and repair work will take place. Motorists will be signed to continue on 11th Street to 1st Avenue for about 5 days.
  • Work on Highway 4 in St. James resumed April 30, 2018.
  • The 2018 work requires a detour consisting of Watonwan County Road 56 (1st Avenue), Watonwan County Road 55 and Highway 4. The project detour for 2018 begins downtown and then follows the 2017 detour route to the north.
  • 2018 project work includes the completion of concrete pedestrian ramp and sidewalk that didn’t get completed in 2017, along with street and utility reconstruction north of 8th Avenue North in St. James. Permanent lane markings will be placed in 2018 and boulevard trees will also be planted.

Hwy 4 businesses are open

Hwy 4 through the city of St. James is in poor condition and in disrepair. The city utility infrastructure is also in poor condition and is currently experiencing multiple breaks each winter. MnDOT received municipal consent for the project in December 2014. The project includes reconstruction of approximately 1.6 miles of Hwy 4, including two new mini-roundabouts. Project elements include:

  • Reconstruct Hwy 4 from approximately 200 feet south of 10th Avenue S. to 11th Avenue N.
  • Realign 7th Avenue S. to address the skew and increase safety
  • Construct mini-roundabouts at the two existing signals on 1st Avenue
  • Provide back-in diagonal parking downtown
  • Replace existing sidewalk and install new sidewalk
  • Bring all pedestrian accommodations up to Americans with Disability Act (ADA) standards
  • Upgrade city utility infrastructure - storm sewer throughout the corridor
  • Upgrade lighting standards and fixtures
  • Downtown aesthetics (PDF)

Tree removal

Native trees will be planted along Hwy 4 in residential areas following completion of construction work. Approximately 130 new trees of 8-10 different varieties will provide a more diversified and sustainable urban forest in St. James. In addition, the city of St. James will remove about 75 trees on city streets and is working on a reforestation plan.

Innovative grant

The Federal Highway Administration announced that MnDOT and the city of St. James have been awarded a demonstration grant to construct two mini-roundabouts and back-in-diagonal parking as part of the Hwy 4 reconstruction project in 2016-17. The Accelerated Innovation Deployment grant is for $934,000 and will be applied to the shared cost of the mini-roundabouts replacing signalized Hwy 4 intersections with 7th Street and Armstrong Boulevard in St. James.
