Category 9 - Congestion Mitigation: Bottleneck Reduction

Award of Excellence

State Route 61, Cameron Bridge Project
City of Shamokin, Coal Township, Pennsylvania

Overhead view of the bridge near completion, with the existing bridge still in place.  The new bridge is wider and the alignment smoother to provide for a better flow of traffic.Photo of traffic flowing at the new signalized intersection of SR 61 and the Connector road just north of the bridge.

Originally built in 1851 as a means to cross Shamokin Creek and transport coal by railcar, the Cameron Bridge was replaced in 1933 with a more modern two-span pony truss. However, by the end of the 20th century, the two-lane bridge and intersecting roadways had become inadequate to handle current traffic volumes. Together with PennDOT, the design team came up with a final plan that improves traffic flow and safety, removes a major traffic bottleneck, satisfies the local public, and adds public benefits. This design provides a wider threelane bridge with shoulders and sidewalks; realigns and widens SR 61; incorporates a new five-lane connector road between SR 61 and SR 225 with signalized intersections; and, improves traffic signals and pedestrian crossings along SR 61.
