As part of G&A’s multi-year on-call transportation engineering design contract with the City of Philadelphia Department of Streets,  G&A was tasked with design activities for a pedestrian bridge replacement within the Fairhill section of the City.  The existing pedestrian bridge, built in 1912, was constructed to provide access across four railroad tracks within lands formerly owned by the North Pennsylvania Railroad.  As the rail line had long been inactive the pedestrian bridge created a barrier between the community and the neighborhood school.  G&A designed a new, ADA accessible, connection over the vacated viaduct to provide an at grade street reuniting the neighborhood.  In addition to the roadway design activities, G&A’s environmental and geotechnical teams performed a Phase I Environmental Assessment as well as a Phase II assessment concurrent with geotechnical testing.  G&A provided geological logging of borings, field screening for the presence of contaminants, including lead paint and asbestos and collected samples for laboratory analysis.  During construction G&A also provided limited construction administration to provide technical support to the City.
