PROJECT UPDATE (POSTED NOVEMBER 2025):

A virtual public meeting will be hosted online on November 13, 2025, and an in-person open house plans display will be hosted on November 17, 2025 at 6PM at the Coatesville Moose Lodge. As a result of the feedback received from public involvement events in the fall of 2024, PennDOT and the project team have completed further evaluations and present the following revised alternatives for public review and comment.

WELCOME AND PROJECT BACKGROUND

Thank you for visiting the project website. The US 30 Reconstruction program includes a series of projects that will upgrade the Coatesville-Downingtown Bypass (US 30) to improve safety, reduce congestion, accommodate planned growth, improve facility deficiencies, and improve system connectivity. In 2019 and 2020, the project team presented alternatives to the public for the Western Project Area, including the Western Terminus/PA Route 10, the Airport Road interchange, and the Route 82 interchange. Based on the technical evaluation of alternatives and input received at the meetings, alternatives were selected for each of these three projects.  Exhibits and descriptions of the Airport Road, PA Route 82, and the Western Terminus/PA Route 10 selected alternatives were made available on the project website.

While the Airport Road and PA Route 82 selected alternatives have progressed to Preliminary Engineering, discussions have continued for the Western Terminus/PA Route 10 project area. As a result of further evaluation, a new set of alternatives to include a full-movement grade-separated interchange between US 30 and Business US 30 were developed to better achieve the purpose and needs versus the previously evaluated set of alternatives.

This public outreach effort is to present the revised alternatives for the Western Terminus/PA Route 10 project area for review and input. The revised alternatives plans and the decision matrix tables are provided below on this webpage. A Virtual Public Meeting will be held on Thursday, November 13, and an In-Person Open House Plans Display will be held on Monday, November 17, 2025 to present this same information.

EXISTING CONDITIONS

The existing interchange of US 30 and Business US 30 provides both eastbound and westbound on-ramps and off-ramps. The existing intersection of US 30 and PA Route 10 is an at-grade, signalized intersection.

  • The existing Western Terminus provides an eastbound on-ramp and connection to eastbound Business US 30.
  • The existing Western Terminus provides a westbound off-ramp and connection from westbound Business US 30.
  • The existing intersection of US 30 and PA Route 10 is signalized.

PURPOSE AND NEEDS

Purpose 

The purpose of the project is to provide a safe and efficient transportation system by improving safety, reducing future congestion, accommodating planned growth, and improving facility deficiencies.

Needs

The project needs have been identified: Safety, Facility Deficiencies, and Congestion/Anticipated Growth

  • Safety – Several locations within the project corridor have crash rates that exceed the statewide average for the same type of facility. Peak travel time congestion, narrow or absence of shoulders, and inadequate signalization and traffic signal phasing contribute to the high crash rates.
  • Facility Deficiencies – Substandard roadway conditions exist throughout the project corridor. The existing pavement within the project area is approaching the end of its useful service life. The outer (right) shoulders are narrow and deteriorated. Two structures currently have insufficient vertical clearance.
  • Congestion/Anticipated Growth – The existing traffic at the signalized intersection of US 30 and PA 10 currently exceeds the capacity during certain periods of the day, which results in congestion and driver delay. In the future, growth is anticipated to continue along US 30 and PA 10 in the area, resulting in higher vehicular traffic volumes and further congestion and delay.

ENVIRONMENTAL RESOURCES

Some of the significant environmental features of the project area include farmland, a church, a nature preserve, township open space, historic properties, six streams, and 12 wetlands. A total of 15 active agricultural parcels are present, one of which is in the Sadsbury Township Agricultural Security Area. The Gateway Grace Community Church is located south of US 30. The Sadsbury Woods Preserve owned by the Natural Lands Trust is located to the north of US 30. Sadsbury Township open space used for recreation abuts the preserve. There are two historic properties along the highway west of the US 30/Business US 30 merge. Buck Run is the main stream present and, along with its five tributaries, supports natural trout reproduction. Two of the wetlands present are open-water farm ponds. The remaining 10 wetlands support predominately emergent vegetation and are considered to of exceptional value due to their connection with the Buck Run streams.

US 30 MAINLINE

The existing typical section and the proposed typical section for US 30 mainline is illustrated in the graphic below. The proposed typical section has not changed from the previous public outreach.

REVISED PROJECT ALTERNATIVES

As a result of further evaluation, revised alternatives have been prepared to address public feedback from the fall of 2024.

ALTERNATIVE R2A

  • U.S. 30 and Route 10 will remain as a signalized intersection with added lanes.
  • U.S. 30 and Business U.S. 30 will become a grade-separate interchange.
    • Interchange provides one single-lane roundabout and one loop ramp with no direct local road connection.
    • New roadway connection is provided between Old Mill Road and Compass Road for local traffic, the plain sect, and emergency access.
    • Closure of Compass Road intersection to U.S. 30.
  • Adds a new structure near Old Mill Road to traverse Buck Run.

ALTERNATIVE R2B

  • U.S. 30 and Route 10 will remain as a signalized intersection with added turn lanes.
  • U.S. 30 and Business U.S. 30 will become a grade-separate interchange.
    • Interchange provides one single-lane roundabout and one loop road with no direct local road connection.
    • New roadway connection is provided between U.S. 30 and Compass Road at the Nova Way traffic signal for local traffic, the plain sect, and emergency access.
    • Closure of Compass Road intersection to U.S. 30.

ALTERNATIVE R2C

  • U.S. 30 and Route 10 will remain as a signalized intersection with added lanes.
  • U.S. 30 and Business U.S. 30 will become a grade-separated interchange.
    • Interchange provides one single-lane roundabout and one loop road with no direct local road connection.
    • Maintain right-in and right-out movements at Compass Road intersection to U.S. 30 and allow left turns into Compass Road for emergency vehicles only.

DECISION MATRICES

NOISE IMPACT

The Western Terminus/Route 10 Project Area (Section 10) is currently in the Conceptual Design phase, which will take approximately one year to complete. The next phase will be Preliminary Engineering and Environmental Evaluation, which is anticipated to last approximately two to four years. Final Design will follow, with a two-to-four-year timeframe.

The following graphic illustrates the steps within the noise evaluation process. The use of noise barriers will be evaluated during the Preliminary Engineering and Environmental Evaluation phase. Additional public meetings and special process meetings will be held as the project progresses to discuss the possible use of noise barriers.

NOISE EVALUATION PROCESS

RIGHT OF WAY INFORMATION

Since the Western Terminus/Route 10 Project Area (Section 10) is currently in the Conceptual Design phase, property impacts are not yet known. Should your property be needed for transportation purposes, you will be contacted, and you may be assured that PennDOT’s Right-of-Way Representatives will gladly answer any questions you may have. You may also be assured that it is PennDOT’s intention to achieve the best possible transportation facilities while maintaining your satisfaction as a private landowner.
