Harrison Avenue Bridge Over Roaring Brook

Replacing a Historic Landmark
Scranton, Pennsylvania

Scranton, known as the "Electric City" in the late 19th century because of its quick adoption of electric street lighting and streetcars, needed a formal bridge across Roaring Brook due to early 20th century population growth. The result was a three-span reinforced concrete arch structure completed in 1922. While the bridge lived for years as a local historic icon, the strain of carrying more than 15,000 vehicles a day prompted a decision that met the deteriorating conditions head-on.

We completed a comprehensive condition survey that included an in-depth inspection, material testing, and a rigorous structural analysis. Our survey showed that rehabilitation would not solve long-term durability and feasibility concerns, so we recommended a complete bridge replacement. To pay homage, numerous portions of the newly designed bridge will be reminiscent of the original, including curved and arch-shaped design elements, similar pillars, a hunched shape, as well as period-style metal fencing and lighting. We also worked in partnership with local stakeholders while we relocated and redesigned neighboring Duffy Park. We incorporated similar design themes and installed an interpretive panel describing the original bridge. In addition, the park gained period-style lighting and amenities including winding sidewalks and a parking area.
