Skirball Center Dr Bridge Demolition & Reconstruction

Completed Skirball Bridge, South View 

• Detours
• Freeway Closures
• Fact Sheet

The Skirball Center Dr Bridge will be the second bridge demolished and reconstructed to accommodate the widening of the I-405 freeway to add a high-occupancy vehicle lane through the Sepulveda Pass. Following the Skirball Center Dr Bridge, the Mulholland Dr Bridge will next be demolished and reconstructed.

When completed, the expanded Skirball Center Dr Bridge will be widened by approximately 30 feet and designed to the latest seismic standards. It will also feature higher capacity southbound on-and off-ramps relocated south of the Skirball Center Dr Bridge. This will improve traffic flow by reducing conflict with Sepulveda Bl traffic lanes and alleviate congestion on the bridge.

Demolition activities will take place over seven nights. The Skirball Center Dr Bridge will be closed intermittently during those first seven nights of demolition, with freeway and parallel ramp closures occurring as well. Some intermittent closures will occur during the preparation for bridge demolition and bridge reconstruction. Detour maps and routes will be available to enable drivers to avoid this area during bridge demolition.

The I-405 freeway and Sepulveda Bl will not, however, be closed simultaneously. And even during reconstruction, the Skirball Center Dr Bridge will accommodate two lanes of traffic in the westbound direction and one lane of traffic in the eastbound direction after the first phase of demolition. Access will always be provided for emergency responders.

To reduce the work’s effects on local traffic flow, Skirball Center Dr Bridge demolition and reconstruction will be conducted in two separate phases. The northern side of the bridge will be demolished first. That will be followed by approximately seven months of north-side bridge reconstruction. Upon completion of the north side, the southern side of the bridge will be demolished and rebuilt in the same manner.

To further minimize its effects on project neighbors, the I-405 Sepulveda Pass Improvements project has closely coordinated its construction with the City of Los Angeles Bureau of Engineering, whose project can be found by clicking here.

The completion of the north half of the Skirball Bridge is anticipated for late 2011.
