The Bears unveiled a nearly $5 billion proposal Wednesday for an enclosed stadium next door to their current home at Soldier Field as part of a major project that would transform the city’s lakefront, and they are asking for public funding to help make it happen.

The plan calls for $3.2 billion for the new stadium plus an additional $1.5 billion in infrastructure. The team and the city said the project would add green and open space while improving access to the city’s Museum Campus and also could include a publicly owned hotel.
