I-405 Sepulveda Pass Widening

“Carmageddon Project”

Kiewit oversaw the demolition of the Mulholland Bridge, coined by the media as “Carmageddon” for its potential impacts to Los Angeles’ heavily congested traffic corridor.

Approximately 18 miles of retaining walls.

This design-build project involved constructing one 10-mile HOV lane northbound on I-405 from the I-10 to US-101.
