Harrisburg, PA – The Pennsylvania Department of Transportation (PennDOT) invites the public to an online plans display regarding the Route 4007, Section 018 (Stone Arch Road) superstructure replacement project over an Unnamed Tributary to Buffalo Creek in Juniata Township, Perry County. The purpose of this project is to replace the existing superstructure and provide continued safe and efficient crossing of Route 4007 over the Unnamed Tributary to Buffalo Creek.
The existing rolled, steel I-beam bridge was built in 1948 at a 44-degree skew to the roadway. The span length is approximately 26 feet.
This project involves removing the existing bridge superstructure and replacing it with a new superstructure. The existing single span, steel beam superstructure will be replaced with a new pre-stressed concrete, spread box beam bridge with concrete deck and barriers.
In addition to the replacement of the superstructure, minor approach roadway reconstruction, along with guide rail, pavement marking and signing updates will also be completed as part of the project. The proposed roadway curb to curb width will remain similar to the existing conditions with 11-foot lanes and variable width shoulders (1 foot and 4 inches minimum to 3 foot and 2 and ½ inches maximum.). The variable shoulders are the result of the bridge following a straight alignment while Stone Arch road follows a horizontally curved alignment (Radius equal to approximately 407 feet.)
This section of Stone Arch Road has an average daily traffic volume of 259 vehicles per day (vpd) with 11% trucks.
The bridge will be closed to all traffic for approximately 6 months during construction. The detour will be approximately 3.74 miles using Creek Road, Milford Road, Oak Hall Road and Buckwalter Road.
No underground utilities will be affected by the project. Utility work will include one utility pole relocation, a minimum of one temporary/permanent utility pole installation, and aerial line relocation.
The project is currently in design, and construction work is anticipated to begin in Spring 2027 and last approximately 6 months.
The purpose of the plans display is to introduce the project and solicit public input, questions, or concerns regarding the project.
A digital version of the information will be available to view online, with a comment period through September 26, 2025.
