The 405 expansion project otherwise known as "Carmageddon 2" begins this Friday, Sept. 28. with ramp closures starting at 7 p.m. and lane closures starting at 10 p.m. By midnight, the I-405 freeway will be completely closed between the I-10 and U.S. 101 until Monday at 6 a.m., cutting off the biggest North-South artery in the city for 53 hours.
While officials are laying off the apocalyptic messaging this time, the 2012 closures could result in more congested traffic than last year. Contractors have to accomplish 30 percent more work in the same allotted time, and the closure's September timing means that UCLA students are back in town for school.
There are also several mass events around town, like a triathlon, Dodger games and concerts at the Hollywood Bowl that will result in either additional road closures or heavier surface street traffic.
Officials recommend using public transportation, walking or biking to eat, play and shop locally -- but if you must drive, here is the Carmageddon 2 schedule and alternate routes and maps that will help you plan your weekend.
