Summary of work

MnDOT is scheduled to begin construction at the Interstate-90 and Hwy 63 interchange just north of Stewartville spring of 2020.  The 2-year project will address several existing conditions including: intersection safety issues, congestion issues, functionally obsolete bridges, inadequate deceleration, acceleration and merge lanes, and sight issues.

Proposed changes

  • Close Hwy 30 access to Hwy 63 at current location, the new Hwy 30 will follow Olmsted County Rd 8 north to Olmsted County Rd 16 east then to Hwy 63 south
  • Construct extension of 90th St. SE to the east then north to connect to 85th St. SE
  • Construct new westbound I-90 entrance ramp further to the north
  • Construct new loop ramp for westbound I-90 to southbound Hwy 63
  • Construct new ramp for westbound I-90 to northbound Hwy 63
  • Replace Hwy 63 bridges, widened for 3 lanes and shoulders, extended acceleration and merge lane for northbound Hwy 63
  • Lengthen deceleration lane for eastbound I-90 exit to northbound Hwy 63
  • Construct new eastbound I-90 entrance ramp further to the south
  • Close median south of interchange

     

Traffic Management

  • Construction is planned for two years, rebuilding one bridge each year
  • Traffic on Hwy 63 will be reduced to one lane each direction and shifted for bridge work
  • ¬†Traffic detours will be utilized when highway ramps are closed during construction
  • A temporary traffic signal will be placed at Schumann Drive on the north end of Stewartville to manage traffic flow
  • I-90 traffic will have occasional overnight detours during bridge demolition and beam placement
