At least six teams comprising the world’s largest contractors, engineers and bankers have been assembled to compete for a limited number of shortlist slots to build Florida’s I-4 Ultimate toll road through downtown Orlando.

Over 800 have signed up for an industry briefing on Mar. 4. An RFQ will be issued March 8 with responses due March 29. But the big game is set for May 10, when the shortlist is scheduled to be announced.
