The BSL follows the 'old' path of Broad St, which as someone posted earlier took a different path around city hall. So from a purely engineering standpoint you would have an extremely complex engineering project here involving building a new structure atop two submerged heavy rail lines... 8 tracks in total plus non-public access tunnels that are there as well.

I think the commuter tunnel runs underneath the front plaza but you're right, the BSL tunnel probably does run underneath the depression. It doesn't mean you can't building anything there but it does mean it's either likely to be very substantial to justify the costs or not very substantial. Still, even a one story retail strip would be better than what's there now...or move the ice skating rink as johnnie noted.
