The John F Kennedy Center for Performing Arts - REACH Expansion Pedestrian Bridge
The John F Kennedy Center for Performing Arts REACH expansion included a pedestrian bridge to connect the new expansion to the Potomac river bike path in order to provide easy access for the public to these new facilities. The unique design of the bridge featured a trapezoidal steel box cross section with various internal stiffeners and diaphragms to create a continuous 300ft long structure supported on five intermediate piers. The bridge climbed 15ft in a 200ft span parallel to the Potomac river and Rock Creek Parkway, at a safe elevation for clearance on the road underneath the bridge took a 106 degree turn to pass over the Rock Creek Parkway and connect to the Kennedy Center’s new expansion. The bridge was fabricated in six sections and partially assembled on site in a pre-staging area for accelerated erection to minimize impact to traffic on the road below. Bridge sections were shop painted with complex 4 coat paint system and touched up in the field with extensive joint blending using filler compound to create the aesthetic of a continuous section without joints. Bridge was finished with a stainless steel cable railing and aluminum SlipNot walking surface.
