How about this, a complete rebuild of the TSC road network, make it flow as good as it does at the Legends. You can go to Nebraska furniture mart during a Nascar or Sporting KC event and not even get stuck in any traffic. Literally went to NFM during a sporting KC game yesterday and it's like there wasn't even 20k people across the street.
Getting into and out of TSC requires way to many left turns across traffic which kills traffic into and out of the complex, we need some cloverleafs or flyovers to solve this, I hate cloverleafs but you have to admit having a ton of them at the legends makes it work.
The area south of the stadium isn't going to develop into anything fancy so lets just admit what would go best around the stadium, more tilt up warehouses which is what Hunt Midwest specializes in (win win), it's at a major highway crossroads and with a bunch of overbuilt streets, it would be perfect to build tons and tons of warehouses which generate taxes and have a ton of workers which give customers to any new fast food and small retail that can added to this area. Plus everybody knows we need more affordable housing, so if we ever connect this site to downtown with a streetcar, it is the perfect location to build a bunch of affordable apartments so people can work in the area or ride the streetcar to other jobs in the city. (another win win situation)
