  18. 18. Stenton Avenue Bridge (S.R. 3003) over Wissahickon Creek Whitemarsh Township, Montgomery County Setting The bridge carries a 2 lane road over a stream in a rural setting with pasture land and forest at three quadrants of the bridge. The fourth quadrant includes a large ca. 1960 dwelling. Bridge Description Built in 1914 Total length of 168 feet as measured from end to end of wingwalls 2-Span Masonry Arch Bridge (clear spans of 30’ and 26’) comprised of rubble-coursed field stone spandrel walls and parapets with concrete capstones that continue across the wingwalls. The voussoirs of the arch rings are partially parged. The intrados are parged, and concrete toe walls have been placed.

  20. 20. Stenton Avenue Masonry Arch Rehabilitation Completion Date: 2010 Cost: $1,050,000 Designer: TranSystems Owner: PennDOT District 6- 0 Preservation Combination20 TRBADC50 / Preservation Partnerships / ByWays to the Past
  21. 21. Stenton Avenue Bridge Average daily traffic: 9,774 vehicles per day. Important transportation link. Critical Condition due to masonry superstructure condition with several Priority “0” and “1” recommendations requiring timely repairs. Preservation Combination21 TRBADC50 / Preservation Partnerships / ByWays to the Past
  22. 22. Existing Structure Large sections of bulging spandrel walls. Preservation Combination22 TRBADC50 / Preservation Partnerships / ByWays to the Past
  23. 23. Structure Was in Critical Condition Sections of the masonry walls exhibited cracks, bulges and missing or displaced stones. The structure was classified as Structurally Deficient. Preservation Combination23 TRBADC50 / Preservation Partnerships / ByWays to the Past
  24. 24. Heavy Efflorescence on Intrados Coating Overall, the barrels were in good condition and suitable for reuse in the rehabilitated structure. Preservation Combination24 TRBADC50 / Preservation Partnerships / ByWays to the Past
  25. 25. Substandard Bridge Railings •Existing roadway width (20’-10”) was determined to be adequate for traffic volumes. •Masonry barriers inadequate height and strength. •Substandard guiderail connections. Preservation Combination25 TRBADC50 / Preservation Partnerships / ByWays to the Past
  26. 26. How Significant Issues Were Resolved Replace earth fill with lightweight concrete fill. Reconstruct stone masonry parapets with reinforced concrete cores and full width moment slab. Repoint masonry as needed. Scour repair and protection. Preservation Combination26 TRBADC50 / Preservation Partnerships / ByWays to the Past
  27. 27. Typical Section Reinforced concrete moment slab constructed on the new lightweight concrete fill and existing arch barrel. Preservation Combination27 TRBADC50 / Preservation Partnerships / ByWays to the Past
  28. 28. Temporary Support of Arches Arch “centering”, constructed of a timber and pipe scaffolding system, installed to stabilize the arches during rehabilitation. The existing bituminous pavement, earth fill, masonry parapets and deteriorated sections of the spandrel walls were removed. Preservation Combination28 TRBADC50 / Preservation Partnerships / ByWays to the Past
  29. 29. Utility Replacement Since the utilities would ultimately be encased in the concrete fill, carrier pipes were installed that would permit the smaller diameter utility pipes to be installed after the bridge rehabilitation. Preservation Combination29 TRBADC50 / Preservation Partnerships / ByWays to the Past
  30. 30. Removal of Earth Fill Concrete fill was placed over pier and abutments to stabilize the structure during masonry reconstruction. Preservation Combination30 TRBADC50 / Preservation Partnerships / ByWays to the Past
  31. 31. Replaced Earth Fill With Lightweight Concrete Fill Deteriorated sections of the spandrel walls were reconstructed and concrete fill was placed up to sub-grade level of the new reinforced concrete moment slab. Preservation Combination31 TRBADC50 / Preservation Partnerships / ByWays to the Past
  32. 32. Finished Concrete Moment Slab Full width reinforced concrete moment slab with integral concrete barriers was constructed on the concrete fill. The barriers were faced with stone and finished with an integral concrete capstone for aesthetics. Preservation Combination32 TRBADC50 / Preservation Partnerships / ByWays to the Past
  33. 33. Typical Slab/Parapet with Reinforcement Detail Preservation Combination33 TRBADC50 / Preservation Partnerships / ByWays to the Past
  34. 34. Concrete Core Barrier Stone facing was also provided on the fascia. Preservation Combination34 TRBADC50 / Preservation Partnerships / ByWays to the Past
  35. 35. Repointing of Masonry Repointing was performed in accordance with the PennDOT Stone Arch Bridge Maintenance Manual and NPS Standards. Preservation Combination35 TRBADC50 / Preservation Partnerships / ByWays to the Past
  36. 36. Finished Roadway Section •A bituminous wearing surface was added to the concrete moment slab to provide the appearance of the original structure. •Note increased parapet height and improved guiderail attachments.

  38. 38. Edges Mill Road Bridge (S.R. 4015) over a Branch of Beaver Creek Caln Township, Chester County Setting The bridge carries a 2 lane road over a stream in a rural setting. Bridge Description Built in 1916 Total length of approximately 180’ feet as measured from end to end of wingwalls 3-Span Masonry Arch Bridge (clear spans of 24’-7, 24’-8 & 24’-2) comprised of rubble-coursed field stone spandrel walls and parapets with concrete capstones that continue across the wingwalls. The intrados of each span has been parged. Preservation Combination38 TRBADC50 / Preservation Partnerships / ByWays to the Past

  49. 49. Lessons Learned/Conclusions Through the development of a streamlined repair methodology, PennDOT District 6-0 has been able to efficiently and cost effectively rehabilitate it’s structurally deficient masonry arch bridges. Over the past 2 years, construction contracts for over 25 masonry arches, have been let employing these procedures.
