The MTA Universal Pedestrian Bridge consists of an exposed V-section steel through-truss supported by four HSS columns with a span of nearly 150ft across Lankershim Boulevard.
MTA Universal Pedestrian Bridge Project Highlights & Challenges:
Design for towers and stairs delayed significantly, which created layout issues for interface with the walkway structure.
Complexity of design was too ambitious, as modeling progressed connections were reconfigured to suit what was more practical for the shop and to more sound connections.
As mentioned above, the structure was “V” shaped and spanned between (3) street corners, basically made up of pipes most with multiple diagonal cuts. These pipes also required “T-Y-K Welds” (Pipe Prep Transition welds) and a lot of experimentation with electronic files that would work for the fabricator.
To add to the shop weld & field connection challenges; many portions of the structure had stringent AESS requirements that had to be met.
