Mulholland Dr Bridge Demolition & I-405 Closure

The demolition of the north side of Mulholland Dr Bridge has been scheduled for Saturday, September 29 and Sunday, September 30, 2012. As with the demolition of the south side of the 608-foot-long bridge, the I-405 through the Sepulveda Pass will be closed in both directions that weekend to allow for demolition.

As with the south side demolition, Metro and Caltrans are concerned that closing the freeway will result in severe congestion on the I-405 and adjoining freeways, perhaps effecting freeways throughout the region. Motorists throughout the State of California are asked to “Plan Ahead, Avoid the Area, or Eat, Shop and Play Locally.”

To reduce the impacts on local traffic flow, the Mulholland Dr Bridge will be demolished and reconstructed in two separate phases. During July 16 and 17, 2011, the south side of Mulholland Dr Bridge was demolished.

The north side of the bridge is expected to be completed 12 months after demolition. During reconstruction, the Mulholland Dr Bridge will accommodate one lane of traffic in each direction.

The Mulholland Dr Bridge will be the third bridge demolished and reconstructed to accommodate the widening of the I-405 freeway and to add a northbound high-occupancy vehicle lane through the Sepulveda Pass. When completed, the expanded Mulholland Center Dr Bridge will be widened by approximately 10 feet and will be designed to the latest seismic standards.

Reconstruction has begun on the 608-foot-long bridge and is expected to take approximately 11 months. Upon completion, the northern side of the bridge will be demolished and rebuilt in the same manner.
