Unfortunately, few U.S. airports rarely offer the ease or public transport connections into their affiliated cities that Heathrow does, but one rare exception is Salt Lake City, a major Delta hub, which just this week debuted TRAX, a light rail train into downtown. Trains depart every 15 minutes, and with a 20-minute ride, it is easy to hit the main downtown sights – Salt Lake is wrapping up a $5 billion downtown infrastructure renaissance that includes the new Leonardo Science Museum, new Natural History Museum, new mixed use indoor/outdoor City Creek Center, along with existing attractions such as Temple Square, the most visited site in the State.
