In 2025 Crews will begin to build a fly-over lane that allows southbound Hwy. 52 motorists seeking eastbound I-90 to bypass the left turn that currently exists at the interchange.

MnDOT has previously indicated that increasing traffic volumes on northbound Hwy. 52 have made the left turn onto the eastbound I-90 onramp more dangerous. The agency reduced traffic at the intersection to one lane in an attempt to reduce crashes at turn

The project plans also call for building a new entrance ramp to eastbound I-90 to the south of the current ramp.

Crews will also reconstruct the eastbound I-90 overpass at the interchange in 2025. Work to rebuild the westbound I-90 overpass is set to start in 2026. 

MnDOT says the newly-constructed bridges will give drivers better sight lines and will last for 60 years. 

Once the work starts, motorists will have to navigate single-lane traffic on I-90 and Hwy. 52. Temporary ramp detours will also be in place during the construction. 

The I-90/Hwy. 52 interchange project is one of seven major construction projects happening in southeast Minnesota this year. Keep scrolling to see the others.
