West of I-41/US-41, it continues as a surface road past the Green Bay–Austin Straubel International Airport towards Highway 54.

The route has an exit at County Highway GV (Monroe Drive) before terminating at I-43 in Bellevue.

[2][3] The highway first appeared in 1975 with the completion of the six-lane Fox River span between Ashwaubenon and Allouez.

By 1984, the freeway was extended easterly to its terminus at Interstate 43, which along with US 41 and I-43 completed the circular bypass of Green Bay.

[1] A large-scale two-year reconstruction project of the Fox River bridge deck and its approaches, costing $37 million, has been completed.
