405 Freeway Closure: 'Bridge Bash' Closes Highway In Orange County (MAP, VIDEO)

Attention Angelenos: if you don't need to go to Orange County this weekend, then avoid it like the plague.

That's because our OC brethren are going to be put through their own mini-version of Carmageddon with the total closure of the 405 freeway between the 605 freeway and SR-22 highway junctions. The closure begins Saturday, Aug. 17 at 9 p.m. If all goes well, it will end on Sunday, Aug. 18 at around 5 p.m.

Dubbed the "Bridge Bash," the closure will give construction crews a 20-hour window to demolish the old connector between southbound 405 freeway and eastbound SR-22 highway. The connector was reconstructed to make room for a new carpool connector, explains the Orange County Transit Authority, so it's a little pain for a lot of gain.

The OCTA has a list of what exactly will close, as well as a alternate route suggestions, for the brave souls willing to take their chances on the road this weekend.


  • Northbound 405 freeway will be closed at Valley View St.
  • Southbound 405 freeway will be closed between the 605 freeway junction to the eastbound SR-22 connector (near Valley View Street)
  • 7th St. / Eastbound SR-22 will be closed at southbound 405 freeway junction

Currently, the southbound 405 freeway ranks as the second most congested freeway in the United States. Check out the rankings of other terrible roads, many of them in Southern California, in the slideshow below.
