Between Badger and Roseau
Area 3: Hwy 11 in Greenbush
Limits: Highway 11 between Highway 308 and Highway 89, intersection of Highway 308 and Highway 89
Primary Improvement: Realign intersections and address access management issues
Number of Alternatives: 4
Problem Alternative is Addressing: Safety problems due to intersection skew: Hwy 11 intersects both Hwy 308 and Hwy 89 at a skewed angle, Hwy 89 and Hwy 308 currently intersect with each other in a “Y” intersection. High concentration of access on Hwy 11 between Hwy 308 and Hwy 89.
Option A: Realign intersections so Hwy 308 is route to border and construct frontage road north of Hwy 11
Description:
Intersection Realignments:
- Realign Hwy 11 and Hwy 308 to intersect at 90 degree angles
- Close existing intersection of Hwy 11 and Hwy 89: Hwy 89 traffic would use 330th Avenue
- Realign Hwy 89 and Hwy 308 intersection to intersect at a 90 degree angle
- Realign 310th Street intersection with Hwy 89
Access Modifications:
- Construct frontage road north of Hwy 11 between Hwy 308 and Hwy 89
- Close several driveways on Hwy 11
Estimated Construction Costs: $2,000,000-$2,500,000
Right of Way Needs: Right of way from 13 parcels, with one parcel at southeast corner of Hwy 11- Hwy 308 intersection likely to be a total take.
Environmental Concerns: Potential for state-listed rare features.
Risks: Cost of right of way acquisition and requirement that Hwy 89 connect to border.
Benefits: Improve safety:
- Realign intersections to 90 degree angles
- Consolidate access onto Hwy 11
Option B: Realign intersections so Hwy 308 is route to border and convert Hwy 11 to a three-lane section
Description:
Intersection Realignments: Same as Option A
Roadway Expansion:
- Expand Hwy to three-lane section between Hwy 308 and Hwy 89
Estimated Construction Costs: $2,000,000-$2,500,000
Right of Way Needs: Right of way from seven parcels, with one parcel at southeast corner of Hwy 11- Hwy 308 intersection likely to be a total take.
Environmental Concerns: Potential for state-listed rare features.
Risks: Cost of right of way acquisition and requirement that Hwy 89 connect to border.
Benefits: Improve safety:
- Realign intersections to 90 degree angles
- Center turn lane would reduce conflicts between through and turning vehicles
Option C: Hwy 89 realignment and frontage road or three-lane section
Description:
Intersection Realignments:
- Realign Hwy 89 so it intersects Hwy 11 at a 90 degree angle
- Realign 330th Avenue so it intersects Hwy 89 at a 90 degree angle
- Close existing intersection of Hwy 11 and Hwy 308: Hwy 308 traffic would use Hwy 89
- Realign Hwy 89, Hwy 308, and 310th Street so intersections are at 90 degree angles
Access Modifications/Roadway Expansion Options:
- Frontage road OR three-lane section between Hwy 308 and Hwy 89
Estimated Construction Costs: $4,000,000-$5,000,000
Right of Way Needs: Right of way from up to 11 parcels, with one parcel at northeast corner of Hwy 11- Hwy 89 intersection likely to be a total take.
Environmental Concerns: Potential for state-listed rare features.
Risks: Cost of right of way acquisition.
Benefits: Improve safety:
- Realign intersections to 90 degree angles
- Consolidate access onto Hwy 11
Option D: Hwy 89 intersection realignment and frontage road or three-lane section
Description:
Intersection Realignments:
- Realign Hwy 89 intersection with Hwy 11 to intersect at a 90 degree angle
- Close existing intersection of Hwy 11 and Hwy 308: Hwy 308 traffic would use Hwy 8
- Realign Hwy 89, Hwy 308, and 310th Street so intersections are at 90 degree angles
Access Modifications/Roadway Expansion Options:
- Frontage road OR three-lane section between Hwy 308 and Hwy 89
Estimated Construction Costs: $1,800,000-$2,200,000
Right of Way Needs: Right of way from up to nine parcels, with one parcel at northeast corner of Hwy 11- Hwy 89 intersection likely to be a total take.
Environmental Concerns: Potential for state-listed rare features.
Risks: Cost of right of way acquisition.
Benefits: Improve safety:
- Realign intersections to 90 degree angles
- Center turn lane would reduce conflicts between through and turning vehicles
