The California city of Los Angeles is expected to suffer unprecedented levels of road congestion this weekend. The city has some of the most congested stretches of highway in the US and arguably the world. However the need to demolish a highway bridge will result in a highway closure, including a key interchange that carries extremely heavy traffic volumes. The I-405 San Diego highway will be closed between the San Fernando Valley and the LA Basin. The stretch shut for the demolition job will be between the busy interchange where I-405 meets the Ventura highway, and will end at interchange where I-405 meets the Santa Monica highway. The interchange where I-405 meets the Ventura highway is reputed to carry the highest volumes of merging traffic of any such interchange in the US. The authorities have been warning residents and commuters for some time over the closure.
