(Dates subject to change)    

Wednesday, October 9 through Friday, October 11; 7 P.M. to 6 A.M. Nightly

  • Southbound Highway 169 will be reduced to a single-lane of traffic from Highway 41 to 145th St. to allow crews to widen the road.

6 P.M. Sunday, October 13 through 3 P.M. Monday, October 14

  • Southbound Highway 169 will be reduced to a single-lane of traffic from just south of County Highway 69/Old Brick Yard Road to Highway 41 to widen and pave the road.

Monday, October 14; 9 A.M. to 5 P.M.

  • Northbound Highway 169 will be reduced to a single-lane of traffic from 133rd St. to Highway 41 to remove guardrail and place barriers.

Sunday, October 6 through late-October

Highway 169 near the new County Highway 14 overpass south of Shakopee will be single-lane, head-to-head travel through mid-November. This temporary traffic shift is necessary to allow construction crews to safely install pipe under the highway.

  • Thru traffic on southbound Highway 169 should stay in the left lane and use the crossover at 145th St. to continue south toward Jordan. Drivers will be head-to-head with northbound traffic for approximately a half mile.
  • Local traffic should stay in the right lane and exit at 145th St. All local traffic must exit the highway at 145th St.    
  • During this time, there will be no access to southbound Highway 169 from County Highway 14.
    • Detour uses County Highway 14 to 145th St. to southbound Highway 169.

Friday, Aug 16 through mid-October  
County Highway 78 is closed between Highway 169 and Emery/ Louisville Rd. The closure has been extended through mid-October due to utility relocations and weather setbacks.

  • The detour uses CH 14 and Louisville Rd or Highway 169 and CH 69 to get around the construction.  

  • Local businesses will continue to be accessible from CH 78 from the east and the frontage roads. 

  • The closure is necessary to complete additional pipe work and concrete paving at the Highway 169/CH 78 intersection.

Upcoming Traffic Impacts: 

(Dates subject to change)

Late-October through mid-November

  • Northbound Highway 169 traffic will use the crossover south of County Highway 14 to shift to the southbound travel lanes. Both directions of traffic will be head-to-head on same side of the road for a half mile.

Description


Scott County and MnDOT designed an interchange at US Highway 169 and Trunk Highway (TH) 41/County Highway (CH) 78.  Scott County was successful in obtaining federal funding to expand the scope of the project to include a proposed overpass over US 169 near CH 14 and extension of the frontage road system along the east side of US 169 between CH 78 and CH 14.  The expectation is to begin construction in September 2018. 
  
MnDOT has concluded that an Environmental Impact Statement (EIS) is not required and has issued a Negative Declaration Order for the project.
 
Additional information including notices for upcoming public meetings on the project will be posted on this page as it becomes available.
 

Purpose & Justification


This project will improve the safety and mobility in this area by removing direct access to US Highway 169. This project is consistent with the long-term vision of converting this segment of US Highway 169 into a freeway. 
 
This project will be funded in part by the Scott County Transportation Sales Tax.
