San Ysidro Land Port of Entry
An integrated team of personnel from Clark and Atkinson completed the $12 million San Ysidro Land Port of Entry (SYLPOE) East/West Pedestrian Bridge project for the General Services Administration (GSA) three months ahead of schedule and with zero recordable incidents. The new pedestrian bridge spans Interstate 5 at the U.S./Mexico border.
The 806-foot SYLPOE bridge spans 30 lanes of Interstate 5 as well as Customs and Border Protection (CBP) facilities at the world’s busiest land port. More than 25,000 pedestrians and 50,000 vehicles pass through the port each day. The new bridge connects an existing transit plaza on San Ysidro Boulevard to the west side of Interstate 5 for pedestrians entering into Mexico.
The cast-in-place bridge includes nine piers with architectural exposed concrete, 2,400 feet of stainless steel mesh panel handrails, two cast-in-place elevated approach ramps, two structural steel approach bridges, and an exposed soffit concrete stair. Despite laydown areas and site logistics divided by the 30-lane highway, vehicle traffic was rarely impacted and ongoing CBP operations were never interrupted during construction.
The SYLPOE project incorporated sustainable features focused on energy efficiency, water conservation strategies, and an integrated design process. Most notably, the team strived to achieve net zero energy in all the occupied spaces; the buildings, on a net annualized basis, will provide as much power as they consume. This would make SYLPOE the first facility open 24 hours a day, seven days a week, 365 days a year, to achieve this in the U.S.
