(L to R) I-95 Turnpike Interchange Corridor Improvements, Penn Street Historic Bridge Rehabilitation, and SR 422 Sinkhole Emergency Repair
Roads & Bridges Magazine named three Gannett Fleming projects to its national 2020 Top 10 Roads and Bridges lists, an honor based on the impact to the people served, project challenges, and impressive scope of work. The Gannett Fleming winners are:
#2 Top Roads List: I-95 Turnpike Interchange Corridor Improvements Project for Sections D10 and D20 in Philadelphia, Pennsylvania
In Fall 2018, Gannett Fleming’s design for I-95 Sections D10 and D20 transformed the region by enhancing mobility and alleviating alternate route congestion for 75,000 daily drivers traveling through the region. This missing link bolstered economic activity and bridged the gap for easier travel on local roads for Bucks County and the greater Philadelphia area. Focused on community communication, the project team also launched an exhaustive public awareness campaign explaining the re-designation of more than 250 highway signs.
#5 Top Bridges List: The Penn Street Historic Bridge Rehabilitation in Reading, Pennsylvania
The historic rehabilitation of the Penn Street Bridge in Reading, Pennsylvania, transformed a deteriorating structure into what the local media called an “impressive gateway to the city.” Guided by community input and Secretary of the Interior’s Standards for Rehabilitation, the design team retained the iconic appearance of the 100-year-old concrete arch bridge while enhancing its structural integrity, extending its service life, and improving safety for motorists and pedestrians.
When a large sinkhole closed a main thoroughfare in Palmyra, Pennsylvania, the Pennsylvania Department of Transportation (PennDOT) and Gannett Fleming developed an innovative solution to support a rebuilt roadway over the Karst limestone formations. The design and construction of a 280-foot-long, 2-foot-deep slab supported by 84 micropiles enabled PennDOT to safely reopen Route 422 just 18 weeks after the highway’s closure. This innovative solution provides a design that can be monitored, minimizes disruptions to travel, and provides long-term protection against future closures.
