T.Y. Lin International (TYLI), a globally recognized full-service infrastructure consulting firm, announces that the new Parkside Pedestrian Bridge has opened to users in Washington, DC. The District Department of Transportation (DDOT) selected TYLI to provide Construction Engineering and Inspection (CE&I) services for the project.
The Parkside Pedestrian Bridge connects the Mayfair neighborhood and Parkside development project to the west with the Minnesota Avenue Metrorail and Bus Transfer Stations and the Deanwood Community to the east. Providing safe, accessible, well-lit pedestrian and bicycle travel, the bridge significantly improves transportation connectivity and eliminates the need for an at-level pedestrian crossing on a heavily trafficked road.
The approximately 400-foot-long Parkside Pedestrian Bridge spans Kenilworth Avenue, CSXT Transportation (CSXT) tracks and right-of-way (ROW), and Washington Metropolitan Area Transit Authority (WMATA) tracks, building, and ROW. The bridge also passes under power transmission lines leased and owned by PEPCO that are located over the CSXT ROW.
The project included the three-span steel truss bridge, two approach spans, and access ramps. The central span is composed by an isostatic single span girder, while the other two spans feature two pinned tied arches. All spans are simply supported.
Other safely improvements included pavement reconstruction, new sidewalks, curbs and gutters, new street and pedestrian lighting, new traffic signs, stairways, and 350-foot-long Americans with Disabilities Act (ADA)-compliant ramps.
At the opening ceremony, DDOT’s Interim Director Everett Lott recognized TYLI’s performance and provided the team with the Director’s Excellence Certificate. This certificate acknowledges TYLI’s ability to meet project needs and exceed the highest standards of excellence.
