Wider bridge improves access for emergency vehicles and pedestrians while reducing the likelihood of car accidents
The Duke Street Bridge replacement has been honored with a Road & Bridge Safety Award from the Pennsylvania Highway Information Association, County Commissioners Association of Pennsylvania, and PennDOT.
Herbert, Rowland & Grubic, Inc. designed the project for Dauphin County, which improves safety for local residents in several ways:
- It improves emergency access for residents who live near the bridge. The original Duke Street Bridge couldn’t carry vehicles weighing more than 3 tons, which meant most of the vehicles operated by the Hummelstown Borough Fire Company and Union Deposit Fire Company couldn’t use the bridge. The new bridge has no weight restrictions, and emergency vehicles can safely cross it (as shown in the attached photo).
- It safely accommodates two lanes of traffic, whereas the original Duke Street Bridge was only wide enough for one lane of traffic at a time.
- It makes it safer for drivers to turn onto South Hoernerstown Road from North Duke Street, thanks to increased intersection radii. Previously drivers of large vehicles turning right onto South Hoernerstown Road from Duke Street would cross into the opposing lane. Limited sight distance at this location meant that opposing traffic could not see these vehicles crossing over into their lane with optimum time to react. The new wider intersection will drastically reduce the likelihood of accidents at this location in the future.
- It provides a new sidewalk. The previous Duke Street Bridge had no existing sidewalk; accordingly, pedestrians would often walk in the roadway lanes to cross from one municipality to the other. The new bridge includes a sidewalk that will enhance safety for pedestrians trying to access the United Water Trailhead and Swatara Creek Trail.
