Juniata River Bridge Replacement 1

Juniata River Bridge Replacement

Erdman Anthony led the consultant design team that provided preliminary engineering, final design, and construction consultation for the $16.9 million Juniata River Bridge Replacement project in Juniata County, PA. The primary focus of the project was to replace an aging 685-foot, four-span truss bridge across the Juniata River, but the final project entailed design for a number of transportation improvements, including:

  • A 730-foot, five-span continuous concrete bridge carrying PA Route 35 across the Juniata River on new alignment;

  • A 676-foot, five-span composite prestressed concrete pedestrian bridge over the Juniata River on the alignment of the old truss bridge;

  • A 162-foot, two-span continuous prestressed concrete bulb-tee beam bridge carrying PA Route 35 over Norfolk Southern railroad tracks to replace the existing structure;

  • A roundabout at the PA Route 35/old U.S. 22 (SR 3005) intersection that was the first one to be constructed in PennDOT District 2-0;

  • A culvert under PA Route 35 providing pedestrian access to a municipal park and emergency vehicular access to an adjacent wastewater treatment facility;

  • A jughandle ramp providing access to the local street network;

  • Improvements to the SR 3002/SR 3005 intersection in Mifflintown; and

  • A new boat ramp and street improvements at the municipal park in Mifflin

A pro-active public involvement program that included a Citizen Advisory Committee helped the team address a variety of local concerns, including outreach to Spanish-speaking communities in the project area. In addition to managing the project and providing highway and structural design, Erdman Anthony established GPS ground control, developed photogrammetric mapping, and provided digital orthophotography for the entire project. Our staff also completed a hydrologic/hydraulic study to evaluate impacts of both proposed river bridges on flood conditions, and each passed the 100-year flood event without overtopping.
