The California Science Center says the shuttle is now traveling along a city street after leaving Los Angeles International Airport property shortly after 2 a.m. PDT Friday.
Benjamin Scheier of the Science Center says the shuttle began rolling out of its hangar about 11:30 p.m. Thursday, beginning its two-day, 12-mile trip to the Science Center where it will go on display.
Los Angeles police Sgt. Rudy Lopez says the shuttle was delayed for a little while on the tarmac after developing a problem with the trailer, but he says the glitch was quickly repaired and the journey resumed.
Now, the spacecraft will travel slowly for the next two hours to a private parking lot where it will have a nine-hour layover as crews deal with power lines farther ahead on the route.
It was expected to move again in the afternoon and through the night. To make room, hundreds of trees were cleared and sidewalks were closed to pedestrians.
The youngest of the shuttle fleet, Endeavour has flown 25 times over two decades.
