About the Interstate Highway 494 project

Mn/DOT - Metro District (St. Paul/Minneapolis)

Project Web site: http://projects.dot.state.mn.us/gcinc/494/

 

Location

• Project will construct one additional through-lane in each direction of I-494 from Highway 5 to Interstate Highway 394, a distance of 7.8 miles, in the cities of Minnetonka and Eden Prairie in Hennepin County
• Northwest ramp at the Valley View Road interchange will be reconstructed
• Highway 62 and Highway 7 interchanges at I-494 will be reconstructed

 

Project cost:

• $ 110 million

 

Background

I-494 is a principal arterial roadway that serves a key role in the metropolitan highway system as:

• A collection/distribution facility for other metropolitan area highways
• An urban bypass for interstate or interregional trips
• Access to/from the rest of the metropolitan area for the rapidly growing population and employment bases in the southwestern suburbs
• Access to the metro area from Greater Minnesota 

 

The I-494 pavement in this corridor has reached the end of its design life and needs to be replaced. Several bridges along the I-494 corridor need either deck or total structure replacement and have inadequate vertical clearances between the road surface and the bottom of the bridge. 

 

Description

The I-494 upgrade will correct such deficiencies by:

• Adding an additional lane in each direction to relieve congestion along the busy corridor
• Constructing outside shoulders to accommodate Metro Transit buses
• Constructing median shoulders wide enough for the full length of the project to be used in the future as an additional lane in each direction.
