Hwy 63 and I-90 interchange improvements

About this project

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
