• Ramp Construction Description

With the north side of Skirball Bridge complete, the south side has been the focus of construction. Support columns in the I-405 median and construction of the anchoring abutments on the east and west extremes await construction and pouring of the bridge deck.

The south side reconstruction of Skirball Bridge is anticipated to be complete in summer 2013.

Enhanced Bridge Features

When completed, the expanded Skirball Center Dr Bridge will be widened by approximately 30 feet and designed to the latest seismic standards.

The new bridge will include a minimum 10-foot-wide travel path on the south side of the bridge to accommodate wildlife movement. This path would function as a wildlife conduit (nighttime hours) as well as a pedestrian sidewalk.

New Skirball Ramps

The new southbound on ramp from Skirball Center Dr opened on Sunday, February 3. The old southbound on-ramp has been permanently closed and will be demolished.

Reconstruction will create higher capacity southbound on-and off-ramps relocated approximately 2,000 feet 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.

Here are several features of the relocated southbound on- and off-ramps:

• Greater ramp storage capacity for vehicles entering and exiting the I-405 freeway
• Dedicated turn-lanes on Sepulveda Bl for vehicles entering and exiting the freeway
• New bike routes on Sepulveda Bl between Skirball Center Dr and the new southbound on- and off-ramps
• New signage directing visitors to the Skirball Cultural Center
• Simpler design of the Sepulveda Bl/Skirball Center Dr intersection, resulting in a safer intersection
• Shorter traffic-signal cycles, enabling improved traffic-signal synchronization to expedite travel throughout the Sepulveda Pass corridor's local street network
