The giant "LAX" sign that's welcomed travelers to the Los Angeles International Airport for the last 25 years is temporarily coming down to make way for major roadway projects. Crews began taking down the 32-foot-tall sign Thursday night, starting with the "X," as part of upcoming reconfiguration of the surrounding roads. Reconstruction will include pedestrian enhancements, improved signage and more direct access to LAX Economy Parking on a 4.4 mile-stretch of reconfigured roadway, according to the Los Angeles World Airports.
