Hwy 4 Reconstruction

St. James

Live webcam for mini-roundabouts in St. James in place through March

MnDOT is temporarily recording and streaming live footage of the recently constructed mini-roundabouts in St. James with a traffic webcam. The webcam is live from January to March 2018, and will be used to monitor traffic flow and performance during winter weather conditions.

During Highway 4 construction in summer 2017, mini-roundabouts were constructed to replace traffic signals at the intersections of 1st Avenue S and Armstrong Boulevard N and 1st Avenue S and 7th Street S. A webcam has been placed near the intersection of 1st Avenue S and Armstrong Boulevard N and directed at the mini-roundabouts.

Traffic impacts

A construction sequencing map of the Hwy 4 project.


  • The 2017 work wrapped up and the Hwy 4 detour was removed on Friday, November 17.
  • The 2018 work will also require a detour consisting of Watonwan County Road 56 (1st Avenue), Watonwan County Road 55 and Highway 4.

While some concrete pedestrian and driveway work will remain to be done in 2018, at least one side along the length of the project will have a hard surfaced sidewalk in place for the winter.
The project detour for 2018 is currently expected to begin downtown and then follow the current detour route to the north. 2018 project work will mainly include the completion of concrete pedestrian ramp and sidewalk that didn’t get completed this year 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 be planted also.

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 parallel 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

Hwy 4 improvements require the removal of approximately 130 trees within St. James, including more than 50 Green Ash trees. The tree removal is necessary to complete the street and underground utility work. Arborists have carefully examined more than 200 trees, the effect the proposed construction activity would have on the tree’s immediate health, and ongoing well-being of the tree prior to determining if tree would need to be removed.

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 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.
