By the most direct route along La Brea Avenue, the distance from Hollywood to Los Angeles International Airport (LAX) is only 12.7 miles, according to Google Maps.
La Brea Avenue is by no means the quickest route to take to get to LAX in a hurry, however. As of June 2015, Google projected the 12.7-mile trip from Hollywood to LAX to take 34 minutes. The quickest route was via the I-110 and the I-105, which at 23 miles was projected to take 30 minutes. There's also a 17-mile option that uses a combination of La Brea, the I-10 and the I-405, which should take about 32 minutes as of June 2015.
