I-76 Full, Partial Closures Sept. 13-20 for Viaduct Rehabilitation, Paving in Center City

Eastbound Interstate 76 will be closed and detoured between the 30th Street and South Street interchanges in Center City Philadelphia from 11:00 PM tonight, September 13, to 5:00 AM Monday, September 16, for pavement repairs and repaving of a section of the Schuylkill Expressway viaduct, the Pennsylvania Department of Transportation (PennDOT) announced today.

During the closure of eastbound I-76, the following ramps will be closed and detoured from 11:00 PM Friday, September 13, to 5:00 AM Monday, September 16:

  • Westbound I-676 ramp to eastbound I-76. I-676 motorists will be detoured west on I-76 to the Montgomery Drive/West River Drive exit, then take the ramp to eastbound I-76 and follow the detour at 30th Street; and
  • Walnut Street ramp to eastbound I-76. Motorists will be directed to follow Walnut Street, turn left on 38th Street and go straight on University Avenue to 34th Street and the ramp to eastbound I-76.

In addition, westbound I-76 will be closed overnight and eastbound I-76 will be restricted to a single lane overnight between the 30th Street and Interstate 676 interchanges for painting and demolition of sections of the overhead viaduct.

Weather permitting, the I-76 work schedule for next week is:

  • Monday, September 16, through Friday, September 20, westbound I-76 will be reduced to a single lane at 9:00 PM, then closed completely from 11:00 PM to 5:00 AM the following morning between the 30th Street and I-676 interchanges for demolition and painting of the Schuylkill Avenue viaduct over I-76. During the closure, westbound I-76 motorists will exit at 30th Street and follow Schuylkill Avenue to the ramp to westbound I-76 or to eastbound I-676;
  • Monday, September 16, through Friday, September 20, from 9:30 AM to 3:00 PM, there will be periodic, short-term closures of the deceleration lane on westbound I-76 approaching the ramp to 30th Street for concrete placement under the viaduct; and
  • Tuesday, September 17, through Friday, September 20, from 9:00 PM to 5:00 AM the following morning, eastbound I-76 will be reduced to a single lane between the I-676 and South Street interchanges for pavement repairs.

Drivers are advised to use an alternate route or allow extra time when traveling through the work areas during the lane closures because significant backups and delays will occur.

Next week’s scheduled overnight closings of westbound I-76 will be adjusted to start later than 11 PM if necessary to accommodate motorists leaving the sports complex in South Philadelphia.

Repairs to the Schuylkill Avenue viaduct are part of PennDOT’s $103.6 million project to rehabilitate the Chestnut Street bridge over the Schuylkill River — which is scheduled to close for one year beginning in mid-June — and eight other nearby structures, including those carrying Schuylkill Avenue over I-76 between Walnut Street and Chestnut Street, and between Chestnut Street and Market Street.

Chestnut Street Bridge Over the Schuylkill River Closed for One Year of Construction in Center City

The Chestnut Street bridge over the Schuylkill River in Philadelphia was closed August 5 for a year of construction to repair and redeck the 62-year-old eastbound connection between University City and Center City, the Pennsylvania Department of Transportation (PennDOT) announced today.

Chestnut Street is closed to vehicles, bicyclists and pedestrians between Schuylkill Avenue near 30th Street on the west side of the river and 23rd Street on the east side. Access from Chestnut Street to the Schuylkill River Trail along the east bank of the river also will close.

During the closure, motorists and cyclists heading east from West Philadelphia will be detoured north on either 38th Street, 36th Street or 33rd Street to east on Market Street, then across the river to 23rd Street.

Chestnut Street motorists in the vicinity of 30th Street also may turn left on Schuylkill Avenue to access either eastbound Market Street or John F. Kennedy Boulevard across the river to Center City.

An alternate detour for cyclists will be to take 38th Street or 34th Street south, turn left on Spruce Street, then east on South Street across the river to 22nd Street.

Pedestrians will be detoured to either the Market Street or Walnut Street bridges over the river.

Motorists are advised to use an alternate route or allow additional time for travel on I-76 near the work area because backups and delays will occur. All scheduled closures are subject to change depending on weather conditions.

PennDOT is rehabilitating the Chestnut Street bridge under a $103.6 million project that also includes the rehabilitation of seven other nearby structures, including two Schuylkill Avenue viaducts over I-76 between Market Street and Walnut Street; the viaduct under Chestnut Street between 30th and 31st streets; the I-76 west ramp to Chestnut Street; the Walnut Street ramp to I-76 east; and the Chestnut Street stone arch bridges over 24th Street and over the CSX rail line west of 24th Street. The contract also includes repairs to a 900-foot section of the “river wall” retaining wall between the river and I-76, and to a retaining wall between the Schuylkill River Trail and the river at Chestnut Street.

Work on the two ramps has been completed. Construction will continue on the remaining five bridges and retaining walls through 2020.

In addition to repairing and repainting the steel superstructure and replacing the deck, improvements to the Chestnut Street Bridge also include:

  • Construction of wider sidewalks;
  • Installation of decorative barrier and railings;
  • Replacement of millennium lighting on Chestnut Street over the Schuylkill River;
  • Construction of a new trellis at the Chestnut Street Trailhead to the Schuylkill River Trail; and
  • Creation of a dedicated bicycle lane on the north side of Chestnut Street between 34th Street and 22nd Street.

The Chestnut Street Bridge over the Schuylkill River, which carries approximately 18,664 vehicles per day is expected to reopen in August 2020. The current bridge was built in 1957, replacing the original iron arch bridge that was built in 1912.

Buckley & Company Inc., of Philadelphia, is the general contractor on the project, which is financed with 80 percent federal and 20 percent state funds. More information is available at www.chestnutstreetbridges.com.

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.  

Wolf Administration Announces Start of Construction on I-76 Viaducts

King of Prussia, PA – The Wolf Administration announced today that construction will begin Thursday night, April 4, on a project to rehabilitate two Interstate 76 (Schuylkill Expressway) viaducts, including the 6,120-foot-long structure between the Interstate 676 and University Avenue exits in Center City Philadelphia and a 345-foot-long structure over Route 23 and Arrowmink Creek in West Conshohocken, Montgomery County.

“Pennsylvania’s ongoing bridge inspection program has been closely monitoring these heavily-used, 60-plus year-old structures to ensure that they continue to function as designed,” Governor Tom Wolf said. “Their analysis of the hundreds of structural components that comprise each viaduct points to the need to address the inevitable deterioration now so as to safely handle the demands of tens of thousands of motorists who use the Schuylkill Expressway each day.”

The two-year project will require numerous overnight single lane closures and full closures in one direction at a time, as well as a limited number of weekend daytime single lane closures or full overnight closures on either the eastbound or westbound expressway in Center City.

For the first two weeks of construction, the contractor will be working on Thursday through Sunday nights on both the eastbound side and westbound side of I-76 in Philadelphia to clear work zone drainage inlets, complete surveying activities, and perform other preliminary work items prior to the start of repairs on the eastbound side of the viaduct that will continue through the end of 2019.

The contractor’s short-term work schedule is:

  • Thursday, April 4, through Sunday, April 7, from 9:00 PM to 5:00 AM the following morning, eastbound I-76 will be reduced to a single lane between the I-676 and University Avenue interchanges; and
  • Thursday, April 11, through Sunday, April 14, from 9:00 PM to 5:00 AM the following morning, alternating eastbound or westbound single lane closures will reduce I-76 to one lane between the I-676 and University Avenue interchanges.

No on- or off-ramps within the work zone are scheduled to be closed during these preliminary construction activities.

Under this project, PennDOT will rehabilitate the 289-span Center City Philadelphia viaduct and the three-span Montgomery County bridge over the 2019 and 2020 construction seasons by repairing or replacing the concrete decks’ expansion joints; repairing deteriorated sections of their concrete decks; rehabilitating numerous piers, columns and other sub-structure components; repairing the viaducts’ drainage systems; and repaving the decks with a concrete overlay.

Repairs to the eastbound side of the Center City viaduct are scheduled to be completed in 2019. Repairs to the westbound side of the Center City viaduct will finish in 2020.

Repairs to the structure in West Conshohocken are expected to begin in May or June 2019 and will be completed by November 2019.  These repairs will be done using single lane overnight closures seven days a week between 9:00 PM and 5:00 AM.

During repairs to the Center City structure, one side of the expressway at a time will be reduced to a single lane or closed completely overnight. In addition, one side of the expressway at a time will be reduced to a single lane during weekend daytime hours a minimum of ten times eastbound (in 2019) and ten times westbound (2020) on non-holiday and select weekends.
