Duke Street Bridge Replacement Project – Hummelstown Borough & South Hanover Township, Dauphin County, PA

HRG designed a replacement for the existing Duke Street Bridge.  This 106-year-old structure carried North Duke Street (T-690) over Swatara Creek to intersect with South Hoernerstown Road (SR 2003).

Specific improvements included:

  • Adding a new 5-foot sidewalk on the west (downstream) side of the bridge to provide safe mobility for pedestrian traffic while meeting ADA requirements.
  • Shifting the North Duke Street alignment to improve clear distance at the United Water Building and meet existing standards.
  • Widening the North Duke Street / South Hoernerstown Road intersection to allow for improved turning movements.
  • Installing a boat launch adjacent to the trailhead for the United Water Trail.
