GIR Construction Update: Fall 2019

Oct 17, 2019

SOUTHBOUND RECONSTRUCTION AT GIRARD

Demolition and reconstruction of the southbound Interstate 95 viaduct and adjacent off-ramp continue this fall along with other related work at the Girard Avenue Interchange.

New deck beams (right) are in place on the southern half of the viaduct — where demolition of the old structure and construction of new support piers began in late 2019 — from approximately Cumberland Street to Palmer Street. Crews began pouring sections of the new concrete deck at the southern end of the new viaduct in late summer and will progress north over the coming months.

South of Cumberland Street, the southbound off-ramp, which was part of the southbound viaduct, was closed in late-July for two years of demolition and reconstruction. Since the closure, crews have been methodically dismantling the original structure (below), working mostly from north to south beginning at Ann Street. Removal of the remainder of the southbound viaduct will continue over the coming months.



While the ramp is closed, southbound I-95 motorists heading for Girard Avenue are being directed to exit at Allegheny Avenue and following the detour route along Allen Street — a temporary stretch of road that PennDOT built alongside northbound I-95 between Cambria Street and Allegheny Avenue — back to the Girard Avenue Interchange area.

Construction also is underway to remove and replace the at-grade section of southbound I-95 concrete pavement from just south of the Allegheny Avenue interchange to the start of the viaduct at Ann Street. Work also continues across the interchange work are to install the project's stormwater management system of pipes and inlets.

In addition, construction continues this fall on the new bridge that carries the southbound Aramingo Avenue spur (left) over Girard Avenue to the southbound I-95 on-ramp and to Delaware Avenue ad the venues along the Delaware Riverfront. The southbound I-95 on-ramp will remain open during most of the reconstruction at the interchange, though several overnight closures may take place during construction of the new on-ramp.

A new retaining wall for the bridge remains under construction along the westbound Aramingo Avenue spur that connects with Girard Avenue.

Related construction to widen Aramingo Avenue approaching the bridge and ramp beginning at York Street also continues. These improvements will be tied-in to the other improvements to surface streets in the interchange area.

Construction of the new southbound viaduct is expected to continue through 2021. The new structure will provide four southbound through lanes as well as a continuous on-off lane that will run between the Allegheny Avenue on-ramp and the Aramingo Avenue on-ramp at the Girard Avenue Interchange.

During the later stages of construction on the GR4 contract, noise barrier walls will be erected atop parapets on southbound I-95 from Indiana Avenue to Palmer Street and along the on-ramp from Aramingo Avenue to southbound I-95. The GR4 contract also includes installation of Intelligent Transportation Systems (ITS) components that are currently under construction at various locations across the region (on I-95, U.S. 1 and U.S. 322) that will assist PennDOT and the City of Philadelphia with traffic and incident management on the region's highways.

In addition, ongoing coordination with community groups through the I-95 Sustainable Action Committee (SAC) during the project's design phase will deliver a number of quality-of-life improvements for those living near the interstate.

PennDOT is investing a significant share of the GR4 contract on improvements to Aramingo Avenue in the vicinity of the interchange and upgrading the areas adjacent to and beneath I-95. 

New sidewalks will be built on Aramingo Avenue between York and Cumberland streets; pedestrian-friendly LED lighting will be installed under sections of the new southbound and northbound viaducts; a multi-use trail will be built beneath and adjacent to the interstate; thematic form lines will be used to decorate wall surfaces on the viaduct's abutments; and a park with expansive stormwater management features will be constructed within the interchange and beneath I-95.

The new and improved southbound I-95 will connect to a 1,200-foot segment of I-95 south of the interchange that was reconstructed in 2013-2015 under the GR2 contract. Northbound I-95 between the Girard Avenue and Allegheny Avenue interchanges, including a new northbound viaduct, was reconstructed under the GR3 contract that finished in 2017.
