Editing Interstate 94 (section)

== History ==
The first section of I-94 completed with Interstate funds (under the [[Federal-Aid Highway Act of 1956]]) was a {{convert|12|mi|km|adj=on}} section between Jamestown and Valley City, North Dakota, in 1958.

North of [[Chicago]], I-94 has been widened from six to eight lanes from [[Illinois Route 22]] (IL&nbsp;22, Half Day Road) to just south of the Wisconsin state line at [[Illinois Route 173|IL&nbsp;173]] and 95th Street to 159th Street. Construction began in 2009 to completely rebuild I-94, including expansion to eight lanes, from the Wisconsin–Illinois border through the Mitchell Interchange in Milwaukee. This construction is expected to be completed in 2021.<ref>{{cite web |url = http://projects.511wi.gov/web/i94northsouth/resources |title = I-94 North-South Freeway Project Resources |access-date = 2014-07-03 }}</ref>{{Update after|2021}}

In 2005, the I-94 bridge over the Crow River near [[St. Michael, Minnesota]], about {{convert|35|mi|km}} northwest of [[Minneapolis]], was rebuilt. In 2006, a project to widen I-94 east of [[Downtown Saint Paul]] between [[Minnesota State Highway 120|MN&nbsp;120]] and McKnight Road from four to six lanes was completed. The interchange at 95th Avenue North in [[Maple Grove, Minnesota]], was rebuilt with a new, wider bridge that replaced the two-lane bridge there, which was demolished in July 2006.

The expanded [[Marquette Interchange]] in [[Downtown Milwaukee]] was completed in August 2008 at a cost of $810&nbsp;million (equivalent to ${{Formatprice|{{inflation|US-GDP|810000000|2008}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}).

In Detroit, I-94 was routed over the existing Edsel Ford Freeway and remained signed as such until the late 1980s when Michigan deemphasized proper names on Interstate guide signs. Its interchange with the [[M-10 (Michigan highway)|Lodge Freeway]], built in 1953, is significant as the first full-speed freeway-to-freeway interchange built in the US.<ref name="significant">{{cite web |url = https://www.environment.fhwa.dot.gov/env_topics/historic_pres/highways_list.aspx |title = Preliminary List of Nationally and Exceptionally Significant Features of the Interstate Highway System |access-date = 2006-07-06 }}</ref>

From September 2007 to October 2008, the [[Minnesota Department of Transportation]] (MnDOT) added a temporary extra lane to I-94 between northbound [[Interstate 35W (Minnesota)|I-35W]] and [[Minnesota State Highway 280]] in the Twin Cities to help relieve traffic congestion caused by the collapse of the [[I-35W Mississippi River bridge]]. As a result, this portion of I-94 was not up to [[Interstate Highway standards]] during this time period.
