Interstate 90 in Minnesota

Interstate 90 (I-90) in the US state of Minnesota runs for 276 miles (444 km) across the southern side of the state, parallel to the Iowa state line. The route connects the cities of Worthington, Albert Lea, Austin, and Rochester. The city of Winona is also in close proximity to I-90, with about 10 miles (16 km) between the Interstate and the city.

Route description

edit

I-90 enters the state from South Dakota near Beaver Creek. This part of Minnesota has flat to gently rolling terrain and is the beginnings of Corn Belt farmland. The flat terrain is often subject to blowing and drifting snow in colder months, and the western portions of the highway are closed multiple times each winter.

Rock County, where I-90 enters Minnesota, is one of the only counties in the state lacking a natural lake. The route passes through the cities of Luverne, Adrian, Worthington, Jackson, Fairmont, and Blue Earth. I-90 has an interchange with I-35 at Albert Lea.

East of the city of Austin, I-90 changes direction slightly and heads toward Rochester, and the route enters a much more hilly landscape. This is the Driftless Area of southeast Minnesota. Unlike the rest of the state, where the most recent glaciations left terrain that is either flat or rolling under a deposit of glacial till, this area escaped the most recent glaciation. The bedrock to the top of the I-90 road cuts is noticeable at this point. The other notable feature of this area are deep, steep valleys cut by water that poured through this area as the ice cap melted.

I-90 drops into the scenic Mississippi River valley just west of Dresbach. The carriageways split apart as they descend, and they rejoin west of the junction with US Highway 61 (US 61). I-90 then parallels the Mississippi River before turning east and crossing the Dresbach Bridge over the river into Wisconsin.

I-90 is atypical in that, just across the Minnesota–Wisconsin state line, (immediately west of the community of Dakota) the median is wide enough that farms exist between the road beds.[2]

Legally, the Minnesota section of I-90 is defined as unmarked Legislative Route 391 in the Minnesota Statutes. I-90 is not marked with this legislative number along the actual highway.

Transit

edit

Jefferson Lines provides intercity bus service along the I-90 corridor from Albert Lea to the South Dakota state line, serving five cities.[3]

History

edit
 
Golden Spike Rest Area near the I-90 midpoint

I-90 in Minnesota was authorized as part of the original Interstate network in 1956. The first section of I-90 in Minnesota constructed was the bypass of Austin in 1961.[4] The wayside rest area near Blue Earth is where the east-building I-90 and west-building I-90 teams linked up in 1978, thus completing construction in Minnesota and joining the 3,099.07 miles (4,987.47 km) of the Interstate.[5] Plaques dedicating the pavement completion and describing the significance of this segment are on display at the rest area.[6] Since being overlaid with bituminous paving in 2006,[7] the original four-foot-wide (1.2 m) gold-colored cement concert line marking the completion of I-90 has been replaced with gold paint on just the shoulder portions of the roadway at the same location.

I-90 in Minnesota closely follows the route of old US 16 over most of its route except from just east of Austin, where I-90 turns toward Rochester and is constructed on a new alignment not previously covered by a highway. The section of I-90 east of Rochester was constructed just south of US 14 and south of the city of Winona.

I-90 served as a replacement for old US 16 between the South Dakota state line and I-90's interchange with present-day Minnesota State Highway 16 (MN 16) at Dexter.
