Interstate 676 Bridge Replacement Project Recognized for Out...

PHILADELPHIA, PA – Pennoni was recognized by the Philadelphia Chapter of the Pennsylvania Society of Professional Engineers (PSPE) for the firm’s work along Interstate 676 (I-676)/the Vine Street Expressway. The project received the Outstanding Engineering Achievement Award – the chapter’s highest honor in the Outstanding Engineering Achievement Program – because the project demonstrates engineering challenges and innovative solutions, the importance of the engineering profession to society, and a clear and tangible benefit to the Delaware Valley region.

Pennoni was selected by the Pennsylvania Department of Transportation to complete the design of and project management for the superstructure replacement of seven overhead bridges, five highways, and two pedestrian walkways along I-676.  The bridges – 22ndStreet, 21st Street, 20th Street, The Free Library of Philadelphia Pedestrian Bridge, 19th Street, The Family Court Pedestrian Bridge, and 18th Street – were determined to be structurally deficient and in need of immediate repair. Pennoni’s design proposed replacing the existing two-span concrete bridge structures with single-span steel superstructures, as well as additional traffic, road, and landscape improvements to complement the redesign of the pedestrian bridges.

Located in Philadelphia’s cultural and historic districts, the project is bounded by such Philadelphia landmarks as Fairmount Park, the Philadelphia Museum of Art, and the Franklin Institute. The design project required coordination with more than 40 private and public stakeholders to see that the improvements were best for the community. Additional coordination was required for the World Meeting of Families and Pope Francis’ first visit to the United States in September 2015.

The award will be presented during the 2015 National Engineer’s Week Banquet hosted by the PSPE Philadelphia Chapter on Saturday, February 27, 2016 at the Springfield County Club, 440 West Sproul Road.
