For months, Los Angeles has been gearing up for the transport of a huge space shuttle fuel tank, aka the giant yellow space banana, from Marina del Rey to Exposition Park, where it will join the space shuttle Endeavour at the California Science Center. (The Endeavour made its own cool, parade-like trip through LA a couple years ago.)

Now, the fuel tank, ET-94, is here and it's gearing up for its move, and that means some brief street closures. LADOT, via KPCC, has maps listing when the streets will be closed and when they are roughly anticipated to be open again, but cautions that the reopening times are dependent on everything going smoothly—the tank moving through and the utilities getting back online in a timely manner.

Also, take note, travelers: the tank is expected to be moving through the area around LAX early Saturday morning. "Passengers heading to LAX from the north were advised to plan ahead and add extra time, especially if taking a morning flight between 6 a.m. and 9 a.m.," says KPCC.
