The Frederick Douglass Bridge in Washington, DC is coming down ... four feet. As a part of the complete reconfiguration of the road system around the new baseball stadium the District Department of Transportation (DDOT) is modifying the Douglass Bridge that carries South Capitol Street over the Anacostia River. A section of the roadway that used to extend two blocks north will now connect at Potomac Ave. To meet at-grade a section of the existing bridge was lowered four feet in late July using a complex system of hydraulic jacks. To capture the glacially-paced procedure DDOT called upon Peter Roof, special projects manager of Creative Video, to create a time lapse of the six hour process. The result was a ten second clip that was made available to local media outlets the next day. "This was probably the most time I've spent for the shortest amount of finished product I've done in my entire career," said Roof. He used the Panasonic HVX200 that was set to capture a full, 1080i high-definition frame every five seconds and record it to a P2 memory card. Nearly thirty hours was spent preparing for and shooting the project. The original product was a seven minute clip. Nicole Mora, editor at Creative Video, used Final Cut Pro to condense it to ten seconds. Preparations began two days earlier with a dry run to test for framing and exposure since nothing can be changed once "rolling." The actual recording began at 5am and the bridge started its four foot journey to its new location around noon. Just before sunset the section was in place and welders began to attach it to new columns. The vantage point was in a nearly abandoned building on the job site. The second story position provided an unobstructed view and protection from the elements. Power came from a generator but Roof took precautions to make sure that power disruptions would not stop the recording. He also took steps to make sure the the camera would not be disturbed by people or animals since a homeless person was still "living" in the derelict building and that pigeons seem to be nesting nearby. The entire recording session was continuously monitored from a parked vehicle just outside the building.
