Milepost 312-316 Reconstruction
Construction and Extension
Construction began in spring 2023 to widen and reconstruct four-plus miles of the Pennsylvania Turnpike from the Downingtown Interchange (Milepost 312) east to the Valley Hill Road bridge (Milepost 316) in Upper Uwchlan, Uwchlan, West Pikeland, and Charlestown Townships in Chester County.
The existing four-lane roadway — with two 12-foot-wide travel lanes in each direction, a 10-foot median, and 12-foot-wide outside 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 (See Typical Section image below).
This project includes the reconstruction and six-lane widening of the PA Turnpike (I-76) between mileposts 312 and 316.
Construction Start: Spring 2023
Construction Completion: 2027
Project Total: $214 million
General Contractor: Allan Myers, L.P.
Construction Manager: Hill International, Inc.
Design Consultant: AECOM
Construction is expected to take approximately four years to complete.
The project also includes the replacement of mainline bridges carrying the Turnpike over Upper Pine Creek Road and Conestoga Road/Route 401. In addition, several culverts passing under the Turnpike will be lengthened, sound barriers will be erected at certain locations, and extensive stormwater management facilities and other drainage improvements will be installed across the project area.
The Turnpike Commission completed a preliminary contract in late fall 2022 to clear trees and other vegetation from within the limits of their right-of-way in advance so as not to impact the construction schedule.
(Pennsylvania environmental regulations require that cutting-down trees greater than 4 inches in diameter must occur between November and March due to the presence of northern long-eared bats, considered an endangered species in this region.) The felled trees are being collected and turned into wood chips.
Bridges within the project limits carrying Bodine Road and Valley Hill Road (SR 1021) over the Turnpike were replaced with longer structures between 2010 and 2013 to provide room for Turnpike widening under this contract.
Construction between Mileposts 312 and 316 is the initial part of a larger Turnpike Commission initiative to widen and reconstruct eight miles of the Turnpike from the Downingtown Interchange at Route 100 east to the Route 29 Interchange in Chester County.
A second contract, which will reconstruct the highway from Mileposts 316-319, is currently in design and expected to go to construction as funding becomes available.
An additional project to widen the Turnpike eastward from Mileposts 324-326 approaching the Valley Forge Interchange is currently under construction.
These projects are funded entirely by Pennsylvania Turnpike toll revenue and have no federal funds or state tax dollars involved.
This project involves a full-depth total reconstruction of four 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.
Frequently Asked Questions
Why is this project being built?
This project is part of the Pennsylvania Turnpike Commission’s statewide total reconstruction initiative which entails rebuilding sections of the 60-plus-year-old Turnpike facility from the ground, up. The new roadway design meets current interstate design standards and will provide a safer and more efficient travel experience for Turnpike customers. The existing pavement conditions, current traffic volumes, and projected growth dictate widening the mainline from four to six lanes.
Are the locations of the noise walls as shown on the mapping final?
Yes. The locations shown on the map located on the News & Public Involvement page are the final locations for the construction of noise walls on this project.
How did you determine where the noise walls are located?
For communities where noise abatement consideration is warranted, the next step is to consider whether the noise abatement would be feasible for each affected community. Traffic noise abatement is typically provided by using highway noise barriers. Feasible noise barriers are those that provide at least 5 dB(A) of noise reduction to noise-sensitive locations and pose no safety, engineering, or access restrictions. If a noise barrier system is determined to be feasible, the next step is to determine whether or not the barrier is reasonable for construction. For a barrier to be reasonable it must be cost-effective and maintenance, constructability, drainage, and utility impacts, as well as the desires of the affected residents, must be considered.
What will the noise walls look like?
The PTC held a community meeting with the property owners bordering proposed noise wall locations to provide them with the opportunity to vote on noise wall color and texture.
The noise walls will consist of concrete panels with steel or concrete posts. The panels utilize a form-liner to provide texture and a stain is applied for color. Anti-graffiti coatings are added in an effort to reduce the possibility of unsightly graffiti.
Go to the News & Public Involvement page for colors, textures, and other information about noise walls and the noise study.
When will the noise walls be built?
The contractor that successfully bids on the project will determine when the noise walls are constructed. Usually, construction access and noise wall fabrication schedules influence the contractor’s decision on when to construct the noise walls.
Where can I view the Noise Impact Analysis report?
A copy of the report can be found in the News and Public Involvement section of this website.
What are you doing to protect the environment?
In addition to coordinating with the local townships, the PTC is working with local, state, and federal regulatory agencies such as the Department of Conservation and Natural Resources, the Pennsylvania Department of Environmental Protection, the Pennsylvania Fish and Boat Commission, and the US Army Corps of Engineers as well as local special interest groups to make sure the project design progresses with the least impact to the environment. The entire project is located in 3 different High Quality watersheds and 1 Exceptional Value Watershed. These types of watersheds are waters of special protection requiring an increased level of effort for permitting.
If the Turnpike Commission still needs to acquire all or part of my property (business or residence) for the project, what should I know about the right-of-way acquisition process?
All property for this project has been acquired.
Property owners will be contacted by the contractor, if necessary, for temporary access to accommodate construction activities.
How will the public know when construction starts, and if there will be detours?
The PA Turnpike Commission will provide the local community and Turnpike users with up-to-date information about construction activity in a number of ways.
The project website will be updated regularly to provide the latest construction information.
Information also will be publicized in local media. Regular email updates and travel advisories will be distributed to the project's email subscribers. Sign up for email updates on the Team & Contact Info page.
The PTC will also utilize the USPS to issue materials related to the project as well.
How is this project funded?
The project is funded entirely by Turnpike toll revenue and has no federal funds or state tax dollars involved.
How much will this project cost?
The construction contract is valued at $214 million.
Does the PTC expect to continue widening to the east and west?
The PTC’s goal is to widen the entire Turnpike to 6 lanes. There are currently active projects east and west of this project. Click here to view the website for the widening project of I-76 between mileposts 324 and 326.
Does the Turnpike coordinate their work schedules with PennDOT work schedules?
Yes. The Turnpike coordinates work schedules and also reviews project plans with PennDOT.
