Description: The U.S. General Services Administration and Clark-Atkinson are partnering to begin construction of the San Ysidro Land Port of Entry’s East-West pedestrian bridge.

It is designed to meet new security measures and will better serve the port’s pedestrian traffic. Construction activities currently underway include pile driving, demolition, underground utilities, concrete and steel work, painting and landscaping.
