Description:

The rehabilitation of the 2500-foot long US 1 Wayne Junction Viaduct in the heart of Philadelphia is a major undertaking. The bridge spans SEPTA electrified train lines and many local roads. Deterioration in the steel superstructure of this 1950’s structure led to a poor rating at its latest NBIS inspection. It is a riveted 15-span steel girder multi-girder structure. It has four units; a 7-span unit, two 3-span units and two simple span units. The continuous units contain pins and hangers located nearly at every other span. The rehab is being completed while maintaining 2 lanes of traffic in each direction. It is an extensive $90M rehabilitation that includes redecking and painting. The presentation will focus on one of the key elements of the rehabilitation, the elimination of the existing pins and hangers. The pin and hanger elimination had to be accompanied by changes in bearing fixity and maintaining superstructure movement compatibility at all stages. The eliminations are also occurring in conjunction with the traffic staging, so each line of pin and hangers is not being replaced at the same time. The needed superstructure jacking is occurring from ground supported towers where possible. But in locations over the active rail line a strong back supported on the cantilever portion of the girder is used. There are 90 pin and hangers to be eliminated. Currently Stage 1 of the construction is complete and 30 of the pin and hangers have been eliminated.
