Demolition of the Skirball Center Drive bridge over the 405 freeway begins tonight. The north side of the bridge is scheduled to be taken down first.

The bridge is being demolished and rebuilt as part of the I-405 Sepulveda Pass Improvements Project, which will add a carpool lane to the northbound 405 between the 10 and 101 freeways, among other fixes.

The bridge is scheduled to be fully closed to traffic beginning at 10 p.m. and the southbound 405 from the 101 to the Getty/Sepulveda exit from midnight to 5 a.m.

Here’s the full list of closures. Frequent updates are also posted on the project’s Twitter page.
