Milwaukee County, Wis., basically decided “we have a problem” when it came to road and traffic safety.

 Miami has a long-established reputation as a hub for international business.

So it’s appropriate that Salt Lake City International Airport (SLC) has achieved a barely detectable handoff between the first and second phases of its decade-long $4.5-billion redevelopment program.
