Interstate 794 as proposed on the 1968 Wisconsin Official Highway Map
The East West Freeway defaulted traffic to 6th Street until 1969, when the Marquette Interchange was completed.
Downtown Milwaukee, 1969
The Lake Freeway, along with the Park Freeway west from Juneau Park, was proposed to form an urban loop encircling Downtown Milwaukee. Only a short stretch of the Park Freeway was built, a spur leading east from the North South Freeway to Jefferson Street, while the Lake Freeway was unconstructed north of I-794.
Crossing over the Milwaukee River inlet along the crest of the Hoan Bridge on I-794 south.
Interstate 794 is a short freeway spur connecting the Marquette Interchange at Interstates 94 and 43 in Downtown Milwaukee with the Milwaukee Bayfront and Jones Island on Lake Michigan. I-794 extends the East West Freeway from I-94 to the Lake Freeway, which runs south along Milwaukee Bay to the Daniel Hoan Bridge. A tied arch span, the Hoan Bridge crosses the Milwaukee River Inlet and carries I-794 south onto Jones Island and the Port of Milwaukee.
South of the Carferry Drive interchange (Exit 3), the Lake Freeway transitions into Wisconsin 794 (Lake Parkway). Lake Parkway extends the route southward as a controlled access highway through St. Francis to Pennsylvania Avenue in Cudahy. The parkway section travels below grade south of the tunnels at St. Francis Avenue, while the Interstate portion is entirely elevated.
The Hoan Bridge Project commenced in October 2013 involving the reconstruction of Interstate 794 from the Milwaukee River at Downtown south to Jones Island. The first stage, from late 2013 to late 2014, affected all of east and southbound with the removal and replacement of bridges, concrete overlay and surface repair and redecking of the Hoan Bridge. Northbound work (stages 2A and 2B) started at the end of 2014 and runs through the December 2015. Future work will reconfigure the Lake Interchange where I-794 turns from the East West Freeway onto the Lake Freeway.
A six mile extension of Lake Parkway (Wis 794) was approved by the Southeastern Wisconsin Regional Planning Commission on December 5, 2012. Funding is still needed however for the $207-million project that will extend STH-794 south from Edgerton Avenue to STH-100, mostly adjacent to the Union Pacific Railroad.7
Interstate 794 opened initially as a spur from the Marquette Interchange to Plankinton Avenue (Exit 1D) in 1968. A short extension followed in 1969 to Jackson Street (Exit 1E).1 The Lake Interchange, where I-794 turns from east-west to north-south, was constructed with elements for the unbuilt Lake Freeway north to the Park Freeway.
Origins of the Lake Freeway and Parkway date back 1929 when Lincoln Memorial Drive opened north from Downtown. Residents in Bay View, Cudahy and South Milwaukee sought a similar road to Lincoln Memorial Drive to better connect them with the city center. This led to discussion by city and county officials of a southern extension of the route in the mid-1920s. Plans however were initially sidelined due to the Great Depression, but mid-1930s momentum from Bay View business groups netted official support, with the city commencing funding on a southward extension of the drive in 1936.2
By 1941 a bridge or tunnel was envisioned at the Milwaukee River, with the parkway extending south to the city line. The advent of World War II curtailed progress on f the project through to 1945, when escalating costs resulted in city officials shelving the project. Increasing traffic congestion and the establishment of the Interstate system led to the 1963 Milwaukee County expressway system plan, which included a harbor bridge between Downtown and Bay view. By 1967 the Lake Freeway south to Layton Avenue was included.2
Work on the Lake Freeway kicked off in 1970, with construction of the Danial Hone Bridge since the right of way was already public land. The tied arch bridge was completed in 1974, but was disconnected to other roads. This was due to opposition resulting in lawsuits, petitions and demonstrations from area residents involving the remainder of the Lake Freeway. The bridge was finally connected to area surface roads in 1977.2
Interstate 794 turns south and immediately gains elevation as it prepares to cross the Hoan Bridge. The Hoan Bridge made the news on December 13, 2000, when a section of the approach to the bridge buckled four feet. As a result, I-794 was closed, and fortunately no one was injured. The bridge was relatively new in terms of anticipated bridge life span (having been completed in 1972). Demolition of the affected segment along with construction of the replacement section occurred during the intervening year, and the bridge was fully reopened on November 1, 2001. Please visit Chris Bessert's Hoan Bridge web page for more information and details on this near-tragedy. Photo taken 09/02/05.
An extension of the roadway southward from Carferry Road remained planned, but options varied with a 1986 study comprising a 3.3-mile long four lane arterial along the North Western Railroad tracks. Another proposal involved tearing down 600 feet of the Hoan Bridge and extending the roadway at-grade across an intersection with Carferry Road.3
Work finally started in 1991 on a four-lane controlled access parkway extending I-794 south to Layton Avenue as STH-794. The $130-million, 3.2 mile roadway was designed with a 40 mile per hour speed limit, 10 to 15 foot high noise barriers and landscaping to create a gateway from South Side to Downtown Milwaukee.4,5
Lake Parkway (Wisconsin 794) opened to traffic on October 1, 1999. The four-lane road was the first major road built in Milwaukee since 1978, when STH 119 to the airport opened.2 The parkway is a limited access roadway with just one at-grade intersection at East Oklahoma Avenue and a tunnel below rebuilt Union Pacific Railroad tracks at St. Francis Avenue.4
The removal of the Park Freeway spur north of Downtown as spearheaded by Mayor John Norquist in 1999 included a similar proposal to tear down Interstate 794. While the Park Freeway plan garnered public support as it only handled local traffic, the I-794 plan did not due to regional transportation needs. Backers of the proposal to replace I-794 with a surface boulevard cited reconnecting the Historic Third Ward area with Downtown.6
A later proposal by Mayor Norquist in 2003 suggested extending I-794 west to the Zoo Interchange as part of a plan to reroute I-94 away from the Marquette Interchange prior to its reconstruction. Read more about that on the I-894 guide.
Interstate 794 veers west at the Lake Interchange and quickly encounters a left-hand ramp (Exit 1E) for Milwaukee Street. Merging from the right is a two-lane ramp from Lincoln Memorial Drive by the eastern terminus of U.S. 18. Only a half mile remains before the Marquette Interchange ramps to Interstates 41 and 94. Photo taken 05/09/10.
Progressing westward, Interstate 794 spans the Milwaukee River on the quarter mile approach to the Marquette Interchange (Exits 1A/B/C). Photo taken 05/30/11.
Interstate 94 overtakes the East West Freeway en route to Elm Grove, Brookfield and Madison. Photo taken 05/30/11.
An on-ramp ties into the departing Exits 1B/C from 2nd and Clybourn Streets. U.S. 41 previously overlapped with I-94 west to the Stadium Interchange and south to the Airport Interchange. The concurrency was removed when Interstate 41 was signed in place of U.S. 41 along I-894 in 2015. Photo taken 05/30/11.
Flyovers shuttle motorists from I-794 west to the North South Freeway. Interstates 43 & 94 travel south from I-794 to the Airport Interchange, where I-43 turns west along side I-41 & 894 to Greenfield. Photo taken 05/30/11.
An end shield for I-794 precedes the on-ramp from 11th and Tory Hill Streets ahead of the flyover carrying I-94 west from the North South Freeway. Photo taken 05/09/10.
Historical Perspective from Interstate 794 west
Prior to the upgrade of the Marquette Interchange, a left-hand ramp (Exit 1B) connected I-794 west with Interstates 43 south & 94 east toward the airport. Photo taken 09/02/05.
Travelers headed to Interstate 43 (North South Freeway) north also utilized a left-hand ramp (Exit 1C) from Interstate 794 west. Most movements at the Marquette Interchange were originally left-hand ramps, which was part of why the junction was redesigned. Photo taken 09/02/05.
An end shield was posted for Interstate 794 west ahead of the East West Freeway transition to Interstate 94. This view looks at a state-named assembly which was removed by 2005. Photo taken by Marc Welby (07/03/00).
The left-hand lane defaulted onto Exit 1B while the number two lane was an optional lane for both Exit 1C and 1A. Construction to upgrade the Marquette Interchange took place between 2005 and 2008. Photo taken 09/02/05.
Perspective from Interstates 43 north & 94 west
A lengthy collector distributor roadway system accompanies Interstates 43 & 94 between the Lincoln and Greenfield Avenue overpasses. The c/d roadway connects the North South Freeway with Becher Street and Lapham Boulevard as the mainline advances north two miles to the Marquette Interchange with Interstate 794. Photo taken 06/13/15.
The left-hand two lanes continue Interstate 43 north through the Marquette Interchange toward Whitefish Bay, Fox Point and Green Bay. Photo taken 06/13/15.
A high bridge takes Interstates 43 north & 94 west over the Menomonee River and adjacent industrial areas through to Exit 310C for Interstate 794 east. Photo taken 06/13/15.
Interstate 794 spurs east from the Marquette Interchange to the Milwaukee Lakefront as I-94 turns west toward Miller Park and the western suburbs. Photo taken 06/13/15.
Historical Perspective from Interstate 43 north-94 west & U.S. 41 north
The previous sign posted two miles south of the Interstate 794 referenced the left-hand ramp for the continuation of Interstate 94 west & U.S. 41 north. This movement now utilizes the highest flyover of the Marquette Interchange. Photo taken 09/02/05.
Typical traffic congestion as Interstates 43 north and 94 west prepared to split at the old Marquette Interchange. Two lanes now serve the westbound continuation of I-94. Photo taken 09/02/05.
A lane drop occurred at the ramp departure (Exit 310C) for Interstate 794 east. On this day, much of the traffic congestion was related to traffic continuing north on Interstate 43. Photo taken 09/02/05.
The adjacent off-ramp (Exit 72C) from I-43 north was removed due to the flyover from I-794 west. A new ramp, signed as Exit 72A, departs from within the Marquette Interchange to Michigan Street now. Photo taken 09/02/05.
Perspective from Interstate 94 east
Historical Perspective from Interstate 94 east & U.S. 41 south
Posted within the Stadium Interchange with Wisconsin 175 (former U.S. 41 and Wis 341), this sign formerly referenced left-hand ramps for both I-43 north and I-794 east without control points. The 2007 replacement includes exit tabs and Green Bay / Lakefront for the respective routes. Photo taken by Chris Lokken and Mike Saldivar (08/13/06).
An elevated stretch of Interstate 94 parallels an industrial area along St. Paul Avenue and the Menomonee River preceding the Marquette Interchange. Note that at the time of the 2006 picture, the single lane ramp to continue on Interstate 94 east & U.S. 41 south was closed. Photo taken by Chris Lokken and Mike Saldivar (08/13/06).
Signs for Exits 310B (I-43 north) and 310C, the continuation of the East West Freeway to I-794, were reused during a later stage of the Marquette Interchange project. Photo taken by Chris Lokken (09/21/07).
This diagrammatic sign on outline the former lane allocations for the upcoming stack interchange with Interstates 43 and 794 east. It was removed at the onset of the Marquette Interchange project. I-794 continues the eastward push toward the Milwaukee Lakefront before turning southward to Lake Parkway (Wisconsin 794). Photo taken by Craig Holl (circa 2000).
