Interstate 94 (abbreviated I-94) is a long interstate highway connecting the Great Lakes and Intermountain region of the United States.

Lane configurations

[edit]

Michigan

  • Between Port Huron, MI and Chesterfield Township, MI (2 lanes on each side)
  • Between Chesterfield Township and US 23 (3+ lanes on each side)
  • Between US 23 and Michigan State Highway 14 (2 lanes on each side)
  • Between Michigan State Highway 14 and c. milepost 166 (3 lanes on each side)
  • Between milepost 166 and Interstate 196 (2+ lanes on each side)
  • Between Interstate 196 and Indiana state line (3 lanes on each side)
[edit]

Indiana

Interstate 94 in Indiana is a shorter stretch of highway that still maintains at least 6 through lanes from Illinois to Michigan.

  • As part of the Borman Expressway -- 6 lanes as of 2005 (3x3). Construction is currently underway to expand this section to 8 lanes (4x4).
  • East of the Interstate 80/Interstate 90 intersection to the Michigan state line -- 6 lanes (3x3)
[edit]

Illinois

Interstate 94 runs through downtown Chicago, resulting in some odd lane configurations:

From north to south:

The following sections are being expanded as of 2005 to make ramps safer and to have consistent amounts of lanes:

  • From the Stevenson Expressway to the 47th Avenue Slip -- 14 lanes (4x4 express, 3x3 local)
  • Between the 47th Avenue and 51st Avenue Slip Ramps -- 14 lanes (3x3 express, 4x4 local)
  • 51st Avenue to the Chicago Skyway (Interstate 90) -- 12 lanes (4x4 express, 2x2 local), expanding to 14 by 2007.
  • Chicago Skyway to Interstate 57 -- 8 lanes (4x4)

The following sections have no expansion plans:

  • Ramps to/from Bishop Ford Expressway -- 4 lanes (2x2), with 6 lanes (3x3) between Michigan Avenue and Cottage Grove Avenue
  • Cottage Grove Avenue to Tri-State Tollway and Interstate 80 -- 6 lanes (3x3)

The following sections are being expanded as of 2005 to widen ramps and through lanes, primarily for the Tri-State Tollway:

[edit]

Wisconsin

  • Three lanes each way from Minnesota border to Exit 4 (US 12)
  • Two lanes each way from exit #4 to junction with Interstate 90

  • Together with I-39/90, three lanes each way until suburban Madison
  • 3+ lanes each way through suburban Madison
  • Departs from I-39/90 at unified I-39/90 exit #138A as I-94 exit #240, thence two lanes each way east to suburban Milwaukee
  • 3+ lanes each way through suburbs and city of Milwaukee.
  • South from suburban Milwaukee, 3 lanes each way to Illinois border

Notes

  • Interstate 94 is the only east-west interstate to form a direct connection into a foreign country (Canada). No such interstate ends at the U.S.-Mexico border. At Port Huron, I-94 crosses the Blue Water Bridge into Sarnia, Ontario and becomes Highway 402, which can be used by motorists going to Toronto.
  • Through much of Michigan, Interstate 94 follows the route of Old U.S. Highway 12. In the 1990s Michigan set up an "emergency Interstate" system. This system is designed as a permanent set of detours for Interstates in case an impassable problem occurs on the Interstates (in the case of I-94 in this area, the problem is usually very heavy lake effect snow).
  • Through North Dakota, Interstate 94 follows the route once taken by U.S. Highway 10 west from Fargo.
  • Interstate 494 was originally planned to serve as a loop in Chicago, Illinois and follow Lake Shore Drive along Lake Michigan. After local opposition prevented I-494 from being completed, the number was completely dropped. Portions of the old I-494 exist as US 41/Lake Shore Drive.
  • The I-494/I-694 loop in the Twin Cities has a speed limit of 60 mph (95 km/h) in most places. All highways within the loop are 55 mph (90 km/h), and Minnesota highways outside the loop can go up to 65 mph (100 km/h); 70 mph (110 km/h) if they are Interstate highways.
  • 40 miles (64 km) north of the Twin Cities near Otsego, the Minnesota Department of Transportation (Mn/DOT) operates the Minnesota Road Research Facility, which studies the effect of traffic on various road surface types. Westbound traffic is redirected onto 3.5 miles (5.5 km) of pavement outfitted with thousands of sensors. There is a straight-through bypass (the original highway) that can be used when researchers are examining the road up close.
  • The stretch from Portage, Wisconsin to Madison, Wisconsin in which I-94 runs concurrently with I-39 and I-90 is the longest such stretch of three interstates in the country.
  • U.S. 52 follows I-94 from St. Paul, Minnesota to Bismarck, North Dakota. It is very poorly signed in Minnesota, but is signed very well on maps and in North Dakota.
  • Some parts of I-94 in Illinois are still signed North and South, especially along the Tri-State Tollway. This is because Interstate 94's alignment between Milwaukee, Wisconsin and Chicago, Illinois is north-south. Most signs on the mainline have been replaced with East-West signage in recent years, as of 2005.

Recent news

  • As of 2005; I-94 is undergoing rehabilitation in and around the Detroit area according to MDOT.
