DOT Project-Harrison St to Hwy B/AB
Work completed April 3 - April 10:
The contractors continued to work on the preliminary stages for the project that are necessary to accommodate traffic during the actual reconstruction of the project. In Stoughton, the contractors worked on removing most of the median islands between Rowe Street and Roby Road. They also worked on grading out the widening on the north side of the road west of Kings Lynn Road. The contractors were able to pave these areas with asphalt that will be needed to carry traffic during stage 2 of the contract. The contractors also worked on setting up temporary traffic signals at Van Buren, Kings Lynn and Jackson streets
On the 74 ID north of Roby Road, the contractors worked on moving pavement markings and setting concrete barrier to protect the area by Halverson’s pond for the marsh excavation that will start in this area. They also finished the nighttime work by installing the last of the two culvert crossings needed in this stage. Lastly, they were working on cutting out the east shoulder of the roadway north of Roby Road to allow the placement of fill on this side of the roadway for the widening that will occur at this location.
Anticipated work schedule for April 13-17:
The contractors will continue to work on the rest of the pavement removal, grading and asphalt paving required for the roadway widening to accommodate traffic during stage 2 of the project. This work will also include the completion of the temporary traffic signals for the construction as well.
The contractor anticipates switching to stage 2 for both the city portion and the rural portion north of Roby Road next Friday (weather dependent). Also, there will be a complete closure of USH 51 between South Harrison and West Main Street for the deep utility work in this area. It is anticipated that this closure will begin on 4/21/26. Much more to come on this next week as we get closer to this closure.
USH 51 is mostly open to through traffic in the work zones and will remain this way for most of the 2026 construction. There are a few short-term closures allowed for 2026 and there will be a signed detour in place for these. USH 51 will be closed to through traffic in the 2027 construction season. There is a signed detour in place for the 2027 construction season
Project Details:
US 51 from Harrison Street to Roby Road will include the following improvements:
• Reconstructing from Harrison Street to Kings Lynn Road with a cross section of a Two-Way Left Turn Lane (TWLTL) in between. From Kings Lynn Road to Roby Road will remain as a 4 lane urban configuration.
• Reconstructing sidewalk, curb ramps, and crosswalks to meet Americans with Disabilities Act (ADA) standards.
• Intersection improvement at Hults Road/Jackson Street/US 51 to restrict Hults Road to Right in and Right out. Upgrading the signal equipment at US 51 intersection
US 51 from Roby Road to County B (east) will include the following improvements:
• Reconstruct the existing rural 2‑lane undivided roadway to a 4‑lane urban divided roadway with a raised median.
• Construct 10‑foot‑wide sidewalk on both sides of US 51 up to new pedestrian underpass near RutlandDunn Townline Road intersection.
• Reconstruct the Rutland‑Dunn Townline Road and County B (east) intersections to dual‑lane roundabouts.
• Construct a pedestrian underpass just north of the Rutland‑Dunn Townline Road intersection.

• Install a continuous lighting system in the median.
US 51 from County B (east) to County B/AB will include the following improvements:
• Reconstruct the existing undivided rural roadway to a 2‑lane rural divided roadway with a continuous raised median, including intersection improvements.
• Reconstruct the existing pedestrian underpass just south of the Charles Lane intersection.
2026 Traffic Control
US 51 from Harrison Street to South Quam Drive:
• This segment will be constructed under staged traffic conditions with one lane of traffic maintained in each direction. Some temporary pavement and adjustment to the Hults Road roundabout will be required.
• Short limited duration closures of Mainline US 51 to complete water and sanitary lines including some lateral work.
US 51 from Lake Kegonsa to Charles Lane:
• This segment will be constructed under staged traffic conditions with one lane of traffic being maintained in each direction to accommodate early surcharge construction adjacent to US 51. Off-peak single-lane closures under flagging operations may be used for placement of temporary concrete barrier wall adjacent to the roadway shoulders.
The DOT project website will be updated throughout construction and is currently under creation which will be available before construction begins. An email distribution list will be used to provide weekly updates. If you would like to be added to the distribution list, please reach out to me at the contact information listed below and you can be added to distribution list.
