This is it, folks. The intersection of Aviation and Century boulevards closes tonight at 9 p.m. and will remain closed until 6 a.m. Monday in order to demolish an old railroad bridge to make way for the Crenshaw/LAX Line.

Those headed to Los Angeles International Airport this weekend should either take the Flyaway Bus, transit or use Sepulveda Boulevard to access the airport if driving — and allow for extra time. The above detour will be in effect all weekend.

Some other tips:

•Southern California 511 has launched a new feature to keep drivers up to date during the planned Century Crunch closure scheduled July 25 to 28. To access the real-time traffic information, call 511 and say “Century Crunch” after the automated greeting. You will get info on the intersection closure and learn recommended detour routes. Or say “traffic” to receive frequently updated traffic information on nearby roadways that feed into the LAX area.

•The FlyAway bus offers bus service to and from LAX terminals from six locations: Union Station, the Expo/La Brea station, Westwood, Santa Monica, Hollywood and Van Nuys. Please see the FlyAway website for more information on fares and schedules.

•A free shuttle runs between the Metro Green Line’s Aviation station and the LAX terminals.

•Metro Bus lines serving the airport include Lines 102, 111, 117, and 232.  These lines all terminate at the LAX City Bus Center on 96th Street just east of Sepulveda Boulevard. After getting off your bus, walk a short distance to the west end of the LAX City Bus Center and cross over to the LAX Parking Lot C depot where you catch the free “C” LAX shuttle bus to the LAX airline terminals. Line 102 serves Martin Luther King Jr. Boulevard, Stocker Street, and La Tijera Boulevard. Line 111 serves Florence Avenue and Arbor Vitae Street. Line 117 serves Century Boulevard (click here for info on the 117’s detour route), and Line 232 serves Pacific Coast Highway and Sepulveda Boulevard south of LAX.

•Municipal bus providers with service to LAX include Beach Cities Transit Line 109,Santa Monica Big Blue Bus Line 3, Culver City Line 6 and Torrance Transit Line 8.  All four lines serve the LAX City Bus Center. Beach Cities, Big Blue Bus, and Culver City also serve the Metro Aviation/LAX Green Line Station.

The bus lines that will be affected by the Century Boulevard closure are the Metro Line 40 owl service, Santa Monica Big Blue Bus Line 3, Culver City Bus Line 6 and Beach City Transit Line 109.  On the weekend of July 25 to 27, bus service on these lines will follow recommended detours through the area.

We’ll be updating The Source throughout the weekend with information about traffic and the demolition process.

The latest news release from Metro is posted after the jump:

The news release from Metro:

Century Crunch is this weekend, July 25-28, and those planning to travel to LAX are being reminded that Century Boulevard at Aviation Boulevard will be closed for 57 hours so that an old railroad bridge can be demolished and eventually replaced by a new state-of-the-art light-rail station for the Crenshaw/LAX Transit Project.

The closure will begin at 9 p.m. Friday, July 25, and end at 6 a.m. Monday, July 28. The best advice is to avoid the area but for those who must reach the airport, there are options.

Public transit is the best way to avoid what could be a difficult drive. Metro has five bus lines (102, 111, 117, 232 and 120) and the Metro Green Line serving LAX. Take the Green Line to Aviation/LAX Station. Go downstairs and catch the free LAX “G” shuttle. It serves all terminals. Go to metro.net for details.

The LAX FlyAway bus runs regular service to the airport, as do other municipal lines. The FlyAway links to the airport from Union Station in downtown Los Angeles, the Metro Expo LaBrea Station, Van Nuys, Westwood and Santa Monica. Municipal lines that serve LAX include Beach Cities Transit, Santa Monica Big Blue Bus and Culver City Bus.

Century Boulevard is a major artery to Los Angeles International Airport with more than 92,000 motorists traveling through the Century and Aviation boulevards intersection daily so it is imperative that drivers plan ahead embarking on a trip to the airport during Century Crunch weekend.

If you absolutely must drive to LAX, allow extra time, check real-time traffic conditions by calling 511 on your phone or visiting go511.com on your computer or mobile device. Here is the detour map:

Coming from the south: Drive north on the I-405 freeway, head west on the 105 freeway, exit at Sepulveda Boulevard and go north to LAX. Coming from the east on the I-105 freeway, exit north on Sepulveda to LAX.

Coming from the north: Drive south on the I-405 freeway and exit at either Howard Hughes Parkway or La Tijera Boulevard. At Sepulveda Boulevard head south to LAX.

The $2.058 billion Crenshaw/LAX Transit Project is an 8.5-mile light-rail line that will connect the Green Line with the Expo Line. The Crenshaw/LAX Line is expected to open in 2019.
