There is an existing railroad overpass where that bridge would be located, so people could cross at street level. And as previously mentioned, extending the Underground would work, too.

And although the Skirvin (actually Marcus Hotels) is driving this, they would have to get lots of cooperation from the city, property owners and even the Renaissance Hotel (it currently is attached to the south section of the SF garage).

Would it be so terrible if Marcus profited from this? After all, they invested in the Skirvin and did a fantastic job in restoring and running it -- they've been a great partner with OKC. They also have an excellent reputation for the various properties they own and operate. I have complete trust they could not only pull this off but do it right. They own the Milwaukee Hilton which is adjacent to their new convention center, so they know a thing or two about this.
