Following six nights of Sunset Bridge demolition work that began Friday, July 23, the contractor for the northbound I-405 Sepulveda Pass carpool lane project will continue the demolition of the bridge for one additional night to remove center columns.

The work is anticipated to start tonight, July 29, for one night only between the hours of 9 p.m. and 6 a.m. Two nights of abutment demolition work will follow a month later.

There will be no full freeway closures for this added work but traffic lane reduction in the area of the I-405 and Sunset Boulevard will be implemented both north and south along the I-405 Freeway.

Ramp closures on the Sunset Bridge will be coordinated with Caltrans with ramp closures starting as early at 7 p.m. tonight. Pedestrians will be rerouted to an area outside the construction zone and traffic control officers will be on site to direct traffic.

Emergency access will be maintained on the bridge at all times. Detour maps are available at www.metro.net/405.

Demolition and subsequent reconstruction of the bridge – one of three bridges planned for replacement in the area – is the first major construction milestone for the 10-mile, $1 billion I-405 improvements project.  The replacement of the bridge is required to build a new northbound high-occupancy vehicle lane between the I-10 and U.S. 101 freeways.   Bridge columns will be repositioned to accommodate the additional freeway lane created by the project.  

Closure

Sunset Boulevard (between Gunston Drive and Thurston Avenue)

Background
The $1 billion project, a joint partnership between the Los Angeles County Metropolitan Transportation Authority (Metro) and Caltrans, will create a 10-mile carpool lane on the northbound I-405 between I-10 and U.S. 101 Freeways. The project will add capacity to one of the busiest freeways in the region and make it safer.  Other project enhancements include the improvement of supporting freeway infrastructure such as ramps and sound walls, and the widening of freeway lanes that connect with both the I-10 and U.S. 101.
