This one is kind of a shame. The current stadium is an edge-of-town monster in a sea of parking lots. And so it shall now continue to be for the indefinite future.
The new one was going to be a downtown fixture that would've been a huge boon for public transit, downtown activities, and neighborhood businesses in an area that, frankly, should be doing way better.
No one likes stadium projects, but this is a rare opportunity to show people a better future through practical urbanism. This move helps hold the city hostage by car dependency that much more.
