If you’re heading to LAX you’ll want to give yourself plenty of extra time. Even if you aren’t catching an international flight, the terminal under construction is located in the middle of the traffic loop, so it’s expected to cause cars to back up.
A separate construction project is tying up traffic lanes between Terminal 3 and the International terminal on both the arrival and departure levels. Work is expected to be finished in the Spring of 2013.
