PA 41 Bridge Over White Clay Creek

The Route 41 (Gap Newport Pike) over White Clay Creek existing structure was built in 1927.  The existing structure is a 69 foot, two-span concrete encased I beam bridge. The bridge has an annual average daily traffic (AADT) of approximately 18,300 vehicles per day, including 13% trucks. Route 41 has a posted speed limit of 35 miles per hour across the bridge and through the Borough of Avondale.  Route 41 provides a two-lane crossing of the creek, but expands to include an exclusive left turn lane at each adjacent intersection. There are sidewalks on both sides of the roadway, with pedestrian and bicycle accommodations extending through the borough. The bridge contributes to the Avondale Historic District.

The most recent bridge inspection report noted the superstructure, substructure and deck are all in poor condition.  Stream channel impacts are anticipated to be limited to the immediate vicinity of the existing bridge site because the improved bridge will closely match the existing bridge in length and width.  Minor grading may be required along Route 41 at the approaches to the structure as a result of the construction staging requirements.

At this time, staged construction is envisioned to complete the bridge work. Two lanes of traffic on Route 41 will be maintained during non-working hours. Short term traffic impacts may be required during working hours.
