- The line accommodates 29,000 riders each weekday, connecting the city to the emerging North Shore area and recreational attractions.
The North Shore Connector, a new 1.2-mile light rail line, connects the downtown business district in Pittsburgh, Pennsylvania, with the city’s North Shore, home of the Steelers and Pirates stadiums, four large museums, as well as business and industry.
Gannett Fleming prepared the final design roadway and structural plans for the retained fill and aerial structure next to Heinz Field as part of the Gateway Line for the new North Shore Connector.
Our firm’s services included 160 feet of retained fill and approximately 2,000 feet of aerial structure comprised of simple-, two-, and three-span continuous units supported by trapezoidal, steel box girders. The structure supports continuously welded direct-fixation rail, a station platform, a double crossover, and a storage track facility.
The design effort involved nearly every engineering discipline, as well as project-sensitive coordination with other construction contracts.
- The size of the foundation is above average because the platform carries the weight of a storage area for the cars, which can stack 12 cars deep
- Soft and highly compressible soil was strengthened by using closely spaced stone foundation columns to reduce settlement
- Hydraulic bumpers were provided at the end of the piers as a safety feature.
