As of 2:30 p.m., a report from the contractor, Kiewet, says that all work is on schedule:

•All three girders of the center span of the bridge have been demolished and crews are beginning to clear away the demolished concrete, steel, and dirt pad from under the center span.

•The northern half of the bridge (portion that will remain for 11 months) is now exposed in the center span. Crews are at work thoroughly cleaning the new exposed edges.

•The top deck of the bridge has now been demolished from end to end leaving only girders and bottom deck on the end spans.

•The first of three girders has been demolished on the western span. Work has begun demolishing girders on the eastern span.

•Workers this afternoon will begin to saw through the large concrete beams on top of the columns, an undertaking expected to last into Saturday night.

There is also a good post on the website of Supervisor Zev Yaroslavsky, whose district includes the Sepulveda Pass and the Mulholland Drive Bridge being partially torn down this weekend. Excerpt:

We have 40 hours or less to go, and I urge all of you to stay the course. Stay home, patronize local stores and restaurants, and do everything you can to stay out of your cars until this weekend’s work is completed. It worked last night, and it’s working this morning. We need to sustain this for another day and a half, and then Carmageddon will be in our rear view mirror.
