PA Turnpike Reminds Motorists of 5% Toll Increase

More drivers with unpaid tolls now risk having vehicle registrations suspended under new law

January 25, 2023 –  The Pennsylvania Turnpike Commission (PA Turnpike) reminds drivers that a toll increase approved last year has taken effect across the highway system on Jan. 8 at 12:01 a.m. The Commission approved a 5% increase for E-ZPass and Toll By Plate customers on Aug. 2, 2022. E-ZPass drivers will continue to get the lowest rates, saving nearly 60% versus Toll By Plate. To check toll rates for travel on the PA Turnpike, visit www.paturnpike.com/toll-calculator.

The PA Turnpike also reminds drivers that Act 112 — a measure signed into law on Nov. 3, 2022 — is now in effect. It enables the PA Turnpike to work with the PA Department of Transportation (PennDOT) to suspend motor-vehicle registrations of owners with four or more overdue Toll By Plate invoices or $250 or more in unpaid tolls or outstanding toll invoices. Before Act 112, registration suspensions required a higher threshold of six past-due toll invoices or $500 or more in unpaid tolls.

Thomas Road Closed at PA Turnpike Overpass

January 20, 2023 – Thomas Road is closed between Walker Road and Gulph Road until late winter 2023 for demolition of the existing Pennsylvania Turnpike overpass in Tredyffrin Township, Chester County. Traffic is detoured to Walker Road, Glenhardie Road, and Gulph Road.

Following the full closure, Thomas Road will be restricted to one lane for construction of the new overpass.

This project will widen and reconstruct two miles of the Pennsylvania Turnpike from the Valley Forge Service Plaza (Milepost 324) to the Valley Forge Interchange (Milepost 326) in Tredyffrin Township, Chester County.

The existing four-lane roadway with a 10-foot median and 12-foot-wide shoulders will be converted into a six-lane facility with three 12-foot travel lanes in each direction, a 26-foot median, and 12-foot-wide outside shoulders.

The project also includes replacement of mainline bridges carrying the Turnpike over U.S. 422/N. Gulph Road, Glenhardie Road, and Thomas Road, plus lengthening of culverts, construction of sound barriers at certain locations, and construction of stormwater management facilities and other drainage improvements across the project.

The original project was six miles in length from the Route 29 Interchange (Milepost 320) to the Valley Forge Interchange (Milepost 326). Due to litigation and the current financial challenges facing the Commission, it was broken into two separate construction contracts: This project, plus a second contract for the western two thirds of the corridor from the Route 29 Interchange (Milepost 320) to the Valley Forge Service Plaza (Milepost 324).

Design Details

This project involves a full-depth total reconstruction of two miles of the Pennsylvania Turnpike. Upon completion, the existing four-lane roadway with a 10-foot median and 12-foot shoulder will be converted into a six-lane facility with three 12-foot travel lanes in each direction, a 26-foot median, and 12-foot shoulders.

This project also includes the replacement of three mainline bridges, lengthening of culverts, construction of sound barriers, and the construction of stormwater management facilities and other drainage improvements at various locations throughout the project limits.

Project Plans

This project is part of the Pennsylvania Turnpike Commission's statewide total reconstruction initiative, which entails rebuilding sections of the 70-plus-year-old Turnpike. The new roadway design meets current interstate design criteria and will provide a safer and more efficient travel experience for Turnpike customers. This section is the most heavily traveled four-lane section of the east/west mainline Turnpike, and projected growth dictates additional lanes. In addition to the proposed improvements benefitting Turnpike customers, the adjacent communities will be enhanced through stormwater improvements and noise mitigation.

The project originally extended another four miles west to the Route 29 Interchange (Milepost 320). Due to the funding challenges and to reduce prolonged inconvenience to the local residents, this project is being constructed as the first phase.
