1. Ashmead Road Bridge Replacement

    This existing 58-foot-long steel I-beam bridge in Cheltenham Township was structurally deficient and needed to be replaced because of excessive deterioration. In fact, throughout the course of designing the new bridge, numerous emergency repairs were needed to keep the bridge in service. The bridge is in a high-traffic area prone to flooding, so extra caution…

  2. Mill Road and Horseshoe Trail Road Bridges Rehabilitation

    Two small bridges in West Cocalico Township, one over Little Cocalico Creek and one over a tributary to Cocalico Creek, were deteriorating and needed repairs. Horseshoe Trail Road Bridge was previously closed because of collapsed abutments, and Mill Road Bridge was restricted by a steel plate over a portion of the failed deck. These failing…

  3. SR 2047 Flaugherty Creek Bridge Rehabilitation

    The SR 2047 (U.S. 219 Business) Bridge over Flaugherty Creek is a stone masonry arch bridge listed on Pennsylvania’s Historic Bridge Inventory, and was deemed structurally deficient after 100 years of wear and tear from exposure to the elements and heavy traffic volume. The bridge is one of the few stone masonry arch bridges in…

  4. South Middleton Township Bridge Asset Management Program

    Under National Bridge Inspection Standards, only bridges with spans greater than 20 feet are required to be inspected every two years. When South Middleton Township suspected an issue with a weight-restricted bridge spanning under 20 feet, they had no recent inspection on which to rely. RETTEW completed a bridge inspection for the Township and revealed…

  5. Pequea #5 Bridge

    The Pennsylvania Department of Transportation (PennDOT) identified the existing three-span Pequea #5 Bridge as structurally deficient, so Lancaster County set out to replace it and concurrently address other important public concerns. Specific project goals included eliminating the piers to reduce maintenance costs, accommodating the Amish community, preserving the rural historic district, to which the bridge…

  6. North Locust Street Bridge Replacement

    The existing two-span, 37-foot-long North Locust Street Bridge over Santo Domingo Creek carried 2,400 vehicles per day through Lititz Borough but was structurally deficient due to scour and poor pier condition. Looking for one less structurally deficient bridge in their community, the Borough received federal monies to replace the concrete slab bridge. The Borough wanted…

  7. Newville Road Bridge Replacement

    West Donegal Township closed Newville Road Bridge in the 1990s because of excessive corrosion in its asphalt-filled metal deck pans. After receiving federal funding administered through the Pennsylvania Department of Transportation (PennDOT) for the project, the Township selected RETTEW to develop a new bridge and approach roadway that met both PennDOT and Amtrak design criteria….

  8. Harrison County Road 51 Bridge Replacement

    Closed to traffic for more than three years following an inspection that deemed it unsafe, residents and community members of German Township had to avoid the Harrison County Road 51 Bridge and travel miles out of their way to get to their homes, schools, and businesses. The detour not only delayed emergency responders to the…

  9. Ott Street Bridge Repairs

    Located in the City of Allentown, the Ott Street Bridge over Cedar Creek was in need of repair. With the existing non-composite adjacent box-beam bridge’s fascia beams severely deteriorated and sidewalks forcing the City to close the shoulders. City officials desired a new superstructure that included an architectural treatment and restored safety for both vehicular…

  10. Rettew Mill Road Bridge Replacement

    Keller’s Covered Bridge, the original single-lane single-span Burr-arch wooden truss carrying Rettew Mill Road over Cocalico Creek, is a beautiful historic structure, but its 5-ton weight restriction, limited vertical and horizontal clearance, and insufficient sight distance prohibited it from adequately meeting modern-day transportation needs. Ephrata Township needed to replace this bridge in order to significantly…
