It is still years away, but you could soon see people traveling between Chicago and Sturgeon Bay without ever having to use their own car. Addressing the Door Peninsula corridor's transportation needs is part of the Wisconsin Department of Transportation's 2030 long-range multimodal plan. Much of the WisDOT plan calls for the continued service, preservation, and maintenance of current transportation aspects like area roadways, the Washington Island Ferry, and bicycle/pedestrian routes. The plan also calls for the expansion of rail throughout the region, including an extension of the current Hiawatha Service between Chicago and Milwaukee to extend north through the Fox Cities and Green Bay. From there, the plan calls for a bus route between Sturgeon Bay and the Green Bay rail station and other routes stretching from Marinette to Milwaukee. Noting how transportation needs have changed in big cities, Jon Jarosh from Destination Door County says a bus line between Sturgeon Bay and Green Bay would be great. Still, additional local investments would be needed to handle the visitors once they arrived.

According to Forbes magazine, the number of vehicles on the road could drop from 247 million in 2020 to 44 million in 2030. The plan's third phase includes a bus route that would stretch from Green Bay to Gills Rock, with stops in Egg Harbor and Sturgeon Bay.
