I-76 Viaducts

Construction Update: Winter 2020-21

Construction on Center City Viaduct Nearing Completion

Construction to rehabilitate the Interstate 76 viaduct between University Avenue and 30th Street continues this winter as PennDOT’s contractor completes median replacement (see below) and other work items to rehabilitate the mile-long Center City structure.

The westbound expressway is expected to remain reduced to one lane around-the-clock through February as crews replace the remaining sections of the existing concrete median barrier. In addition to the westbound lane closure, the eastbound off-ramp and westbound on-ramp at South Street will remain closed until the completion of barrier work as well.

Eastbound off-peak and weekend lane closures will continue periodically through late winter as the contractor completes barrier, pavement markings, and other viaduct repairs.

Repairs to the structure’s support columns (see right) beneath the viaduct have been substantially completed. However, repairs to two culverts beneath the expressway between the City Avenue and Belmont Avenue exits — added to the project in late 2020 — will continue through the winter, though with minimal impacts to I-76 motorists.

PennDOT in 2019 began repairs on the topside and underside of the Interstate 76 viaduct between 30th Street and University Avenue in Philadelphia. Throughout 2019 and 2020, PennDOT’s contractor repaired the westbound and eastbound viaduct during overnight and weekend operations.

Completed repairs to the structure included cleaning and refurbishing the viaduct’s stormwater drainage system, repairs to the concrete deck’s expansion dams and parapets, and repaving the viaduct’s riding surface.

PennDOT will continue to issue weekly Travel Advisories to local media and subscribers to the project website. Go to I76viaduct.com for project-related information.

PennDOT has placed an overlay of fast-curing synthetic polyester polymer concrete (PPC) (see below) as a new riding surface on the viaduct’s travel lanes, allowing the viaduct’s surface to be rehabilitated while minimizing the need for long-term lane closures normally required for conventional concrete paving materials.

In addition, PennDOT’s contractor has finished work on the bridge that carries the Schuylkill Expressway over Route 23 and Arrowmink Creek in West Conshohocken Borough, Montgomery County. Joint, bearing, and structural steel repairs to this structure have been completed. Similar repairs to several other I-76 bridges in Montgomery County were made earlier this year.

Construction Update: Fall 2020

Median Barrier Construction Continues

Fall 2020 – Construction to replace the median barrier continues this fall between University Avenue and 30th Street, the final stage of PennDOT’s two-year project to rehabilitate and resurface the Interstate 76 viaduct in Center City Philadelphia that is expected to finish late in 2020.

With the westbound expressway reduced to one lane around-the-clock through the end of the year, crews are removing the existing concrete median barrier and building a new, cast-in-place concrete barrier on the viaduct.

In addition to the westbound lane closure, the contractor is closing one lane of the eastbound expressway at nights and over weekends to speed the repairs. The on and off-ramps at the South Street Interchange also are impacted by the barrier construction, with the westbound I-76 off-ramp to South Street closed through the end of the year, and the South Street on-ramp to eastbound I-76 remains closed until November.

Ongoing repairs to the structural components beneath the viaduct also will continue through late 2020.

PennDOT in 2019 began repairs on the topside and underside of the Interstate 76 viaduct between 30th Street and University Avenue in Philadelphia. Throughout 2019 and 2020, PennDOT’s contractor repaired the westbound and eastbound viaduct during overnight and weekend operations.

As the top side of the viaduct was repaired and repaved during the 2019 construction season, work continued on the underside of the structure, where crews are rehabilitating the viaduct’s support columns. 

Completed repairs to the structure included cleaning and refurbishing the viaduct’s stormwater drainage system, repairs to the concrete deck’s expansion dams and parapets, and repaving the viaduct’s riding surface.

PennDOT will continue to communicate travel impacts in weekly Travel Advisories, which will be issued to local media and distributed through the project website to subscribers. (Sign up at https://i76viaduct.com/more-info/contact to receive travel advisories and other project-related information)

PennDOT is placing an overlay of synthetic polyester polymer concrete (PPC) as a new riding surface on the viaduct’s travel lanes. The PPC cures (dries and hardens) faster than conventional pavement, allowing the viaduct’s surface to be rehabilitated while minimizing the need for long-term lane closures that are normally required for conventional materials.

In addition, PennDOT’s contractor has finished work on the bridge that carries the Schuylkill Expressway over Route 23 and Arrowmink Creek in West Conshohocken Borough, Montgomery County. Joint, bearing, and structural steel repairs to this structure have been  completed. Similar repairs to several other I-76 bridges in Montgomery County were made earlier this year.

Construction Update: Summer 2020

Eastbound Viaduct Repairs Completed, Construction Continues on Westbound Side

Summer 2020 – With construction on the eastbound side of Interstate 76 finishing in early summer, PennDOT’s contractor will focus on completing westbound pavement repairs and resurfacing this summer before shifting to the final stage of the project to remove and replace the median barrier between University Avenue and 30th Street in Center City Philadelphia.

Weekend long closures of the expressway are expected to end once work finishes on the westbound side in August. Median work will then get underway, requiring an around-the-clock closure of a westbound lane between University Avenue and 30th Street through late 2020 for median replacement.

Repairs to the structural components beneath the viaduct also will continue until later in the year.

PennDOT in 2019 began repairs on the topside and underside of the Interstate 76 viaduct between 30th Street and University Avenue in Philadelphia. Throughout 2019, PennDOT’s contractor repaired the surface of a significant part of the eastbound viaduct overnight and weekend operations.

As the top side of the viaduct was repaired and repaved during the 2019 construction season, work continued on the underside of the structure, where crews are rehabilitating the viaduct’s support columns. The contractor is utilizing a construction barge along the west side of the Schuylkill River to reach hard-to-access sections of the viaduct.

Rehabilitation of the surface of the eastbound structure included cleaning and refurbishing the eastbound viaduct’s stormwater drainage system and repairs to the concrete deck’s expansion dams, parapets, and deteriorated pavement overlay. During several full weekend closures of the eastbound expressway in 2019, crews milled and overlayed large sections of the eastbound right lane and shoulder.

During the remaining surface repairs that will take place in the westbound direction in 2020, motorists should anticipate similar impacts to traffic as work is performed on the remaining portion of the expressway. In addition, various on-off ramps may be closed periodically as the work progresses. A revised construction schedule will be published on the project website prior to the start of work in 2020.

Construction Update: Summer 2019

Eastbound I-76 Paving this Summer

The barge on the Schuylkill River

PennDOT’s contractor is making progress on repairing the structural components and the deck of the eastbound Interstate 76 (Schuylkill Expressway) viaduct in Center City Philadelphia and begins resurfacing the eastbound lanes between 30th Street and University Avenue exits this summer.

Crews continue to rehabilitate the support columns on the underside of the eastbound and westbound structure utilizing a barge (right) to reach hard-to-access sections of the viaduct along the west side of the Schuylkill River.

While much of the top-side repairs to the eastbound viaduct’s drainage system, expansion dams, parapets, and concrete pavement are taking place during nighttime operations, paving scheduled for July through September will impact weekend users of the eastbound expressway.

Weekend travel restrictions are scheduled for eastbound I-76 on the following dates:

  • July 19-21;
  • July 26-28;
  • August 9-11;
  • September 13-15; and
  • September 27-29

Additional eastbound restrictions will be scheduled for this fall.

During those weekend operations, which are weather dependent, the eastbound expressway will be closed and detoured:

  • 11:00 PM Fridays to 10:00 AM Saturdays;
  • 10:00 PM Saturdays to 10:00 AM Sundays; and
  • 11:00 PM Sundays to 5:00 AM Mondays.

The eastbound expressway also will be limited to one-lane on those weekends between the closures, and various eastbound on-off ramps will be closed as the work progresses from west-to-east over the designated weekends.

Workers placing PPCThe restrictions will allow crews to place a synthetic overlay (Polyester Polymer Concrete) on the bridge decks (left). The synthetic concrete cures faster, allowing the viaduct’s surface to be rehabilitated while minimizing the need for long-term lane closures that are required for curing conventional concrete pavement.

Between the weekend closures, crews will continue working during the overnight hours weekdays to make repairs to the eastbound viaduct.

Nighttime and weekend construction in 2019 will take place only on the eastbound side.

The westbound side of the viaduct will be repaired in 2020 utilizing similar nighttime and weekend construction activities as are being used on the eastbound side.

PennDOT’s contractor also begins work later this summer on the eastbound and westbound bridge that carries the Schuylkill Expressway over Route 23 and Arrowmink Creek in West Conshohocken Borough, Montgomery County. Construction crews will be performing joint, bearing, and structural steel repairs to this structure.

Work on this bridge will require short-term, overnight single lane closures any night, with extended hours on weekends, in either or both of the eastbound and westbound directions through the fall.

Construction Update: Spring 2019

Construction Underway on Eastbound Lanes

Spring 2019 – PennDOT’s contractor has begun repairs to the long viaduct that carrier Interstate 76 (Schuylkill Expressway) along the west bank of the Schuylkill River between 30th Street and University Avenue exits in Center City Philadelphia.
Work is taking place on the underside of the mile-long structure to repairs the components that support the viaduct. Underside repairs will continue for the entirety of the two-year project.

Construction crews also are ramping up work on the top side of the viaduct, working mostly at night on the heavily traveled expressway. Drainage inlets on both sides of the viaduct have been cleaned out to facilitate stormwater runoff during the construction phases.

Phase 1 construction on the right eastbound lane to repair expansion dams and deteriorated areas of eastbound pavement also is now underway.

Crews also have cleared overgrowth and mobilized a barge to provide access to the underside of the structure from the river.

Nighttime and weekend construction in 2019 will primarily take place on the eastbound side, repairing expansion dams, chipping out and repairing areas of the deck where the existing concrete pavement is damaged, and ultimately resurfacing the two eastbound lanes. The eastbound expressway will be closed overnight along with single-lane daytime traffic patterns approximately ten weekends during the resurfacing efforts in 2019.
The westbound side of the viaduct will be repaired in 2020 utilizing similar nighttime and weekend construction activities as are being used on the eastbound side.

Under this project (SR 76, Section SRE), PennDOT is repairing the long, deteriorated viaduct that carries the Schuylkill Expressway/I-76 along the west bank of the Schuylkill River in Center City Philadelphia.

PennDOT’s contractor also begins work this spring on a bridge that carriers the Schuylkill Expressway over Route 23 and Arrowmink Creek in West Conshohocken Borough, Montgomery County.  Construction crews will be performing joint, bearing, and structural steel repairs to this structure.  Nighttime single lane closures of both eastbound and westbound travel lanes will occur through the Fall.
