Interstate 494 Minnesota

Until late 2006, Interstate 494 crossed the Mississippi River on the 1959-built Wakota Bridge. A multi-year, often delayed project, replaced this steel through arch bridge from 2002 to 2010. The replacement span accommodates ten overall lanes and a bike/pedestrian path between South St. Paul and Newport. Photo taken by Chris Lokken (07/13/06).


Interstate 494 forms the southern and western quadrants of the 73-mile Twin Cities beltway system while Interstates 94 and 694 travel along the northern portion of the loop from Maple Grove east to Oakdale. I-494 and I-694 share end points and an exit numbering system. Exits 1A and 1B are located south of the Minneapolis St. Paul International Airport (MSP) in Bloomington. Numbers count up as I-494 travels clockwise and reset at the Minnesota River.

A mostly suburban commuter freeway, Interstate 494 extends for 42 miles serving communities such as Plymouth, Minnetonka, Eden Prairie, Bloomington, South St. Paul and Woodbury. The route overlaps with Minnesota 5 from U.S. 212 (Exit 11C) to the airport (Exit 1A) along the locally known Bloomington Strip. The north-south segment from Eden Prairie to Interstates 94/694 at Maple Grove parallels a transmission corridor.


Prior to construction of the Interstate system, the Twin Cities were encircled by Minnesota 100, a mostly at-grade belt line. A good comparison can be made with Indianapolis, which also had a pre-Interstate belt line numbered SR 100. The initial stretches of Interstate 494 incorporated upgraded stretches of Minnesota 100, including the overlap with Minnesota 5 from Exits 7 to 1A across Bloomington and MN 100 between South St. Paul and Newport. Upgrades there were completed by 1959. The section at South St. Paul was extended west from Minnesota 156 to 5th and 7th Avenues (Exit 65) in 1960. Construction through 1961 replaced the alignment of MN 5 along 78th Street westward with new freeway through to then U.S. 169 & 212 at Rowland.1

The next portions of I-494 completed were between U.S. 10 & 61 (Exit 63) north to Valley Creek Road (Exit 59) at Woodbury in 1962 and the north-south section from Rowland to Minnesota 7 (Exit 16) at Minnetonka in 1963. Further lengthening of this section followed in 1966 from NN 7 to Minnesota 55 (Exit 22) at Plymouth.1

The links with Interstate 94 from I-494 were open from Exit 59 to Oakdale in 1967 and between MN 55 and I-94 east at Maple Grove in 1968. The full interchange with I-94/694 was not completed until 1973 when Interstate 94 opened to the northwest. This left the east-west portion between the MN 5 freeway at Minneapolis-St. Paul International Airport (MSP) and 7th Avenue in South St. Paul. Litigation delayed this stretch, with construction finally underway by 1980 with completion east across the Minnesota River to Minnesota 55 in 1982. The final stretch took I-494 east to Sunfish Lake and over the original MN 100/110 alignment through Inver Grove Heights to Exit 65 in 1986.1

The Wakota Bridge, named after the two counties it connected: Washington and Dakota, opened in 1959 as part of the original Minnesota 100 belt line encircling the Twin Cities area. The steel arch bridge carried four overall lanes with no shoulders, reflecting a pre-Interstate system design. A $206-million project to replace the aging span started with preparation work at Red Rock Road on November 20, 2001. Originally slated for a fall 2007 completion and split into nine projects, work included widening of U.S. 61 to six lanes through Newport, rebuilding 3.5 miles of I-494 and replacing the bridge across the Mississippi River.2

As work progressed, costs increased to $250 million. Completed construction by late 2003 included redesigns of Bailey Road, Point Douglas Road and Hastings Avenue, local roads tieing into I-494 just east of U.S. 61. These were rebuilt to accommodate access changes for the Wakota Project.3

Issues with the Wakota Project arose in September 2005 when an abnormal amount of hairline cracking in support sections of the new span were discovered during inspection. While the deficiencies did not compromise the structural integrity of the bridge, if left unaddressed, they may have allowed road salt and water seepage to corrode metal support elements and ultimately shortened the 100-year lifespan of the crossing.4

Construction crews retrofitted the span by installing additional support cables as the scheduled completion of the first span shifted from November 2005 to the fall of 2006. With retrofit work taking longer than expected, the overall completion also shifted from 2007 to 2008.4,5 Not long after the first new span opened with two-way traffic in October 2006, the dispute between Minnesota Department of Transportation (MnDOT) officials and the contractor, Lunda Construction Co., culminated when a dispute over costs led the state to release the construction firm. Necessary design changes resulting from the hairline cracks added $15 million to the project costs. The time table for completion was now placed in 2009.6

The 1959 Wakota Bridge was dismantled in January 2007, clearing the way for construction of the new eastbound span. A new bidding process commenced in January 2008 and with the lowest bid, $60.1-million, submitted by Lunda Construction Co. (the same company that MnDOT dropped from the project previously).7 Further actions resulted in a $20 million settlement between MnDOT and HNTB Corp., the engineering firm responsible for the original faulty design of the bridge. A portion of these funds were allocated to the reconstruction of Interstate 494 leading north from the Wakota Bridge to I-94 in Woodbury. Portions of the 1960s era freeway were expanded to six lanes with new concrete poured during work running simultaneously with the Wakota Project.8

The new eastbound span for Interstate 494 across the Mississippi River was finally completed on July 1, 2010. Costing $114 million, nearly twice the original estimates, the ten-lane crossing is the widest bridge in the state and the eighth-longest at 466 feet.9

The I-494 Rehabilitation Project underway from July 2014 to November 2016 expands portions of the freeway between I-394 & U.S. 12 at Minnetonka to the junction with I-94 & 694 at Maple Grove. The $86 million project replaces the concrete surface of the freeway, rebuilds several overpasses and adds auxiliary lanes.

Planned Improvements

Long range plans will upgrade the 1960s-built full cloverleaf interchange between Interstates 35W and 494 on the Bloomington and Richfield city line. Studies in 2014 outlined two interchange designs for the exchange: the Turbine concept and the Clovermill concept. The Turbine adds flyovers in all directions with the exception of I-35E south to I-494 east, while the Clovermill design only adds a flyover from I-35E north to I-494 west. Both were evaluated in their ability to improve congestion and safety while providing a cost effective solution. The Turbine concept was carried forward by 2014.10 See the I-494 and I-35W Study home page for more details.

Western Terminus - Interstates 94 and 694 - Maple Grove, Minnesota
Perspective from Interstate 494 north
This is the first sign advising of the pending interchange with Interstate 94 (and U.S. 52) and Interstate 694 on I-494 north. The final I-494 exit joins the belt line with Hennepin County Route 10 (Bass Lake Road) on the Maple Grove and Plymouth city line. Photo taken 04/22/07.
Attached to the Hennepin County Route 10 overpass, this overhead sign advises that Interstate 494 ends in 1.25 miles at the exchange with Interstates 94 and 694. U.S. 52 is omitted, which is consistent with Minnesota Department of Transportation (MnDOT) signing practices for U.S. highways merged with Interstate highways for long durations. Photo taken 04/22/07.
Interstate 494 originally carried just four lanes from CSAH 10 to Exit 27 with Interstate 94 west. Reconstruction of the freeway during 2014-16 added a third lane in each direction. Expansion of the road removed this sign bridge and state-named shield, the last for I-494 north, by fall 2015.
Travelers otherwise separate at ramps for Interstate 94 west to Rogers and Albertville and I-94 & 694 east to Brooklyn Park and Fridley in one mile. Photos taken 04/22/07.
A third lane for I-494 north previously emerged at the East Fish Lake Road overpass. The mainline defaults onto Interstate 94 west to St. Cloud. Photo taken 04/22/07.
Massive power lines parallel Interstate 494 through to the interchange with I-94/694. These extend north through Maple Grove to the Minnesota 610 freeway. Photo taken 04/22/07.
Northbound Interstate 494 ends as traffic splits for Interstates 94/694 (and U.S. 52). I-694 returns the inner belt east to White Bear Lake and south back to I-94 at Oakdale and Woodbury. West beyond St. Cloud, I-94 travels to Fargo, North Dakota and over the former U.S. 10 alignment to Interstate 90 at Billings, Montana. Photo taken 04/22/07.
Perspective from Interstate 94 and U.S. 52 east
This interchange sequence sign posted one mile ahead of the I-494/694 split, appears along I-94 & U.S. 52 east within the parclo interchange (Exit 215) with CSAH 109 (Weaver Lake Road). Note the absence of a U.S. 52 shield; U.S. 52 is barely signed (if at all) anywhere along its shared alignment with Interstate 94 in Minnesota. Photo taken 04/23/07.
Interstate 94 travels between residential areas of East Fish Lake Road and the Elm Creek Boulevard retail corridor directly to Exit 216 and the Twin Cities belt line. Interstate 494 leads south to Plymouth and Minnetonka while Interstate 94 east continues to Minneapolis and St. Paul. Per area signage, the best bypass around the metropolitan area is via Interstate 694 east. Photo taken 04/23/07.
Traffic separates at Exit 216 with two lanes joining I-494 south to Eden Prairie and two lanes for I-94 & 694 east to Brooklyn Park and Brooklyn Center. Photo taken 06/14/15.
Perspective from Interstates 94-694 & U.S. 52 west
Now traveling west on Interstate 94-694 & U.S. 52 west, this interchange sequence sign provides the distance to the last I-694 exits (all numbered based on Interstate 494-694's mileage). Photo taken 04/23/07.
Interstates 94 & 694 meet the U.S. 169 freeway at a full cloverleaf interchange, 2.5 miles ahead of the I-694 end and I-494 south beginning. Photo taken 06/16/15.
Continuing west from U.S. 169, I-94 & 694 pass between a quarry and residential subdivisions leading to a folded diamond interchange (Exit 28) with Hennepin County 61 (Hemlock Lane). Interstate 494 south departs from the left in less than two miles. Photo taken 06/16/15.
Westbound Interstates 94 & 694 reach the off-ramp (Exit 28) to CSAH 61 (Hemlock Lane). Construction during 2014-16 rehabilitated the concrete pavement of I-494 from Maple Grove south to Plymouth and Interstate 394 & U.S. 12. Additional work also replaced the I-494 bridges at CSAH 47, Schmidt Lake Road and the Canadian Pacific Railway and added auxiliary lanes between MN 55 and East Fish Lake Road. Photo taken 06/16/15.
Interstate 494 south extends the belt line exit numbering system from Exit 27 (the continuation of I-94 west). Interstate 94 and hidden U.S. 52 west travel 43 miles northwest to St. Cloud. Beyond there, truck traffic dissipates on the rural trek to Fergus Falls and Moorehead. Photo taken 06/16/15.
