MnDOT I-494 Inver Grove Heights Project

02/11/2019 update: Construction work will continue on I-494 between Mendota Heights and South St. Paul and may impact your drive later this summer.

The work includes bridge deck resurfacing and joint replacement on the I-494 bridge decks over I-35E, repairing pavement between 3rd Avenue and the east side of the Minnesota River bridge, improving drainage, constructing ponds, as well as adding a turn a lane and replacing signals at I-494 and Pilot Knob Road.

You should expect to see single lane or directional closures of I-494 over approximately twelve weekends as crews complete the pavement resurfacing and drainage work.

The bridge work will occur in multiple stages over two years and will include lane closures.

Note: this work is in addition to the current project on I-494 at Concord St/Hwy 156 .
