The Interstate designation ends at exit 3 at Carferry Drive, which provides access to the Lake Express ferry to Muskegon, Michigan; the highway continues south as State Trunk Highway 794 (WIS 794), also known as the Lake Parkway, to the intersection of Pennsylvania and Edgerton avenues on Cudahy's west side, running parallel and adjacent to the east side of Milwaukee Mitchell International Airport.

[7][failed verification] In a 2016 article for the Shepherd Express, author Michael J. Prigge, pointing out that the bridge had been opened for two years when the film was shot, indicated another incomplete segment of I-794 had been used for the scene.

As part of his campaign for a more livable city in Milwaukee, Mayor John Norquist proposed to tear down the I-794 portion of the east–west freeway in 1995 in favor of a surface boulevard.

His effort failed when suburban opposition to the removal cited increased traffic volume on the road as well as the new Lake Parkway nearing completion.

[9] As of 2023[update], WisDOT is studying several options for reducing the footprint of or demolishing the portion of I-794 between the Marquette Interchange and the Hoan Bridge, with construction tentatively scheduled to begin in 2026.
