All oversize loads entering the City of Marietta, Lancaster County must conform to the requirements set by the Pennsylvania Department of Transportation (PennDOT) and the specific ordinances of Marietta Borough.

In general, any vehicle exceeding 8 feet 6 inches in width, 13 feet 6 inches in height, or a gross vehicle weight exceeding 80,000 lbs should obtain an oversize load permit from PennDOT and may require additional permits or coordination with the Marietta Borough Public Works Department.

Due to the historic nature of Marietta, particularly within the downtown area along Market Street and Front Street, careful route planning is essential to avoid low-hanging wires, narrow streets, and weight-restricted bridges. Coordination with the borough is strongly advised for loads traversing these areas.

Escort vehicles are typically required in Marietta when the load exceeds 12 feet in width, 14 feet 6 inches in height, or 100 feet in length. Specific requirements are determined by PennDOT based on the route and dimensions of the load.

Local police escorts may be required for exceptionally large or heavy loads, or when the route involves navigating particularly challenging intersections or narrow roadways within the borough. Contact the Northwest Lancaster County Regional Police Department for information on fees and scheduling requirements. Expect to pay around $75-$150 per hour, with a 3-hour minimum, depending on the specific requirements.

Applications for oversize/overweight permits are primarily handled through the PennDOT e-Permitting system. Visit the PennDOT website (www.penndot.gov) for detailed instructions and online application forms. For local concerns within Marietta Borough, contact the Public Works Department at (717) 426-3151.

Documentation requirements typically include detailed vehicle specifications, load dimensions and weight, a proposed route map, and proof of insurance. For loads exceeding certain weight limits on borough-maintained roads, a structural analysis of affected bridges may be required.

While PennDOT dictates statewide restrictions, Marietta Borough may impose additional time-of-day restrictions during peak traffic hours, typically between 7:00 AM and 9:00 AM, and 4:00 PM and 6:00 PM, especially on weekdays.

Seasonal weight restrictions may be in effect on certain borough-maintained roads during the winter months (typically December through March) to prevent damage from freeze-thaw cycles. Check with the Marietta Borough Public Works Department for specific road closures and weight limits.

Avoid using residential streets whenever possible. Trucks should utilize State Route 441 (East/West Market Street) and State Route 23 (Marietta Avenue) as primary thoroughfares. The narrow streets and historic buildings in the downtown area are particularly sensitive to heavy traffic.

PennDOT permit fees vary based on the dimensions, weight, and distance of the haul. Base fees typically start around $25-$50, with additional charges for overweight loads, extended routes, and the use of state police escorts.

Marietta Borough does not typically charge separate permit fees for oversize loads, but may assess fees for any damage caused to borough infrastructure. Fees are subject to change and should be verified directly with the borough.
