Northbound Viaduct Construction Progressing, Demolition Heading for Completion
Spring 2016 - Continuing demolition and reconstruction this spring of the mile-long viaduct that carries northbound Interstate 95 travelers between the Girard Avenue and Allegheny Avenue interchanges is expanding the work area at ground level and impacting travel on surface streets in the vicinity of the Girard Avenue Interchange.
Crews began rebuilding the viaduct last winter starting at Ann Street, setting beams (left) and building the deck of the new structure atop new concrete piers. Viaduct construction is moving from north to south.
Working ahead of the viaduct reconstruction are demolition crews, who continue dismantling sections of the old raised structure. With much of the old viaduct already taken down, crews this spring are dismantling the remainder of lengthy structure (right). In areas where the old viaduct passes over surface streets in the vicinity of the Interchange, motorists will encounter closed streets, detours and stoppages during demolition and construction this spring.
As the old viaduct’s pavement and structural components are removed and cleared from the work area, crews are demolishing the old concrete support columns and finishing construction of any remaining new columns — along with the pier “caps” that connect the columns laterally — that are needed to support the new viaduct. Beams are being set in groupings as piers are finished, with deck building and concrete placement following. New Intersection at Richmond Street for New Ramps
Also closed is a section of southbound Richmond Street from Girard Avenue to Delaware Avenue, as well as access to northbound Aramingo Avenue from northbound
Delaware Avenue. These travel restrictions are necessary for construction of the new off and on-ramps and for a new intersection on Richmond Street — between Girard Avenue and Aramingo Avenue — that will provide access to and from the new northbound I-95 ramps (left).
Crews are currently excavating and constructing piers for the new off-ramp. Most of the piers for the new on-ramp are in place along Richmond Street.
The old on-ramp to I-95 north is permanently closed and partially demolished. Motorists normally using the ramp are being detoured north on Richmond Street to a temporary detour road that PennDOT built alongside I-95 north between Cambria Street and Allegheny Avenue. The detour takes motorist east on Allegheny, north on N. Delaware Avenue, and west on Castor Avenue to the on-ramp to I-95 north.
A stretch of Delaware Avenue (right) also is being widened and rebuilt between Columbia Avenue and Aramingo to provide access to and from the new off-on ramps. Motorists face daily travel restrictions for utility placements and other activities at varying locations along that stretch of riverfront roadway during construction. Once the new northbound off-ramp is in place and in use at the new interchange in 2017, the existing northbound off-ramp (Exit 23) will be removed and widening on Delaware Avenue will be completed. At the Southern End of the Interchange
Widening and reconstruction wrapped up late last year at the southern end of the I-95 Girard Avenue Interchange, where crews finished rebuilding and widening 1,200 feet of I-95 between Palmer Street and Frankford Avenue to four lanes in each direction.
Included in the finished work between Palmer Street and Frankford Avenue are noise walls — with transparent top panels (left) — and replacement of the I-95 bridges over Columbia Avenue, Marlborough Street and Shackamaxon Street. The new bridges have decorative walls and LED lighting. Special landscaped areas also were planted along Richmond Street adjacent to I-95 (left photo). These quality of life enhancements were added as a result of interactions between PennDOT and community groups represented on the I-95 Sustainable Actions Committee (SAC).
The work being done on I-95 and alongside the interstate is associated with three of six contracts valued at $342 million to rebuild the I-95/Girard Avenue Interchange and adjoining sections of the highway to the north and south of the interchange. James J. Anderson Construction Company, Inc. of Philadelphia is the general contractor on the three projects.
