Problem: the city of Chicago has multiple urban freeways running through the city center

Solution: we remove Lakeshore Drive and replace it with a slow 2 lane boulevard, lower this section of I-90 west of the Chicago River

Then cap the Freeways around the loop that are below grade such as I-90 and either build new buildings on top of it or build a park. This would turn some of the freeway median parts Blue and Red lines into more traditional Subways so we build walls around the stations that are in the capped freeway median to keep the heat and smog from getting to people. Just fully remove this section of freeway running through Chinatown between I-55, I-90 and Lakeshore Drive

Wait fuck I am doing the Big Dig Again but with Chicago instead of Boston
