Interstate 405, or I-405, will be closed July 16-17, 2011 for 53 hours, affecting ten miles of the 405 Freeway in the Westside of Los Angeles. This freeway is heavily traveled and is bound to disrupt people’s travels, especially mid-summer. The Metro is offering free subway rides during the 405 closure to help people get around the anticipated traffic build-up.
The construction for the freeway widening and the partial demolition of the Mulholland Bridge (map | street view) over the freeway will cost $1.3 billion. A northbound carpool lane will be added to the 405 Freeway between the 10 and 101 freeways, while the bridge will be widened and more resistant to seismic activity. The Los Angeles County Metropolitan Transportation Authority says 500,000 vehicles travel the 405 on a typical mid-July weekend. Officials are advising people to use the Metro Rail service to bypass the massive traffic pile up that is expected during the construction. There will be alternate route solutions posted on the project’s website as well as a few suggestions below.
