We just received a heads up about this great time-lapse video recently posted to YouTube of the old Motor Avenue rail bridge being demolished last week as part of the second phase of the Expo Line between Culver City and Santa Monica.

The old bridge only had room for one set of tracks. The new bridge will have room for two tracks — so trains can easily run in both directions. The second phase of the Expo Line, btw, is a project funded mostly by the Measure R half-cent sales tax approved by L.A. County voters in 2008.

The video credit goes to Mark Morris, a local cinematographer; here’s his website at www.DPmarkmorris.com. Great job Mark and thank you from Metro and the Expo Line Construction Authority!
