PennDOT Announces Online Plans Display for Updates to the Proposed Work Near Thiel College in Greenville, Mercer County


The Pennsylvania Department of Transportation (PennDOT) invites the public to view updated plans for proposed improvements to Route 18 and Route 58 near Thiel College in the Borough of Greenville, Mercer County.

The proposed project area includes Route 18 from the intersection of Route 358 to the intersection with Mill Hill Road, and Route 58 from the intersection with Route 18 to East Craig Street.

The project includes improvements at three intersections, including realignments at Route 18 and Route 58, Route 18 and Packard Avenue, and Route 58 and Packard Avenue. Proposed work also includes new or upgraded sidewalk, curb ramps, driveway entrances, milling and paving, base repair, new traffic signal, drainage updates and pavement marking updates.

The proposal has been updated to include improvements on Thiel College's campus and addition of a cul-de-sac near the intersection of College Avenue and Packard Avenue Extension.

The project is being funded predominately with state and federal funds. Some of the proposed sidewalk improvements on campus will be funded by Thiel College to enhance their ADA accessibility and pedestrian flow.

Construction is tentatively planned to take place in 2024 and 2025.

The information on the Route 18-Route 58 Improvement Project, including a handout, digital plans, and an online comment form are available online. The page will remain active until January 17, 2024 and can be accessed by visiting the PennDOT District 1 website,

Those unable to access the information online may give feedback by contacting PennDOT Project Manager Chris Boyer-Krantz at or 814-678-7379.

The purpose of the online plans display is to inform the community of changes in the impacts of the updated proposed work. The plans display is also an opportunity for the public to review and comment on the project's potential effect upon Cultural Resources pursuant to the Advisory Council on Historic Preservation's 36 CFR Part 800 regulations implementing Section 106 of the National Historic Preservation Act. The public may also comment on the Department's intent to use the Section 4(f) De Minimis Use form for historic resources. 

The project documents will be made available in alternative languages or formats if requested. If you need translation/interpretation services or have special needs or have special concerns that require individual attention, contact Chris Boyer-Krantz, PennDOT Project Manager, at or 814-678-7379.
