All oversize loads entering the City of Quincy, Norfolk County, must conform to the requirements set by the Massachusetts Department of Transportation.

In general, any vehicle over 12 feet 6 inches in width, 14 feet in height, and within the Class 3 weight category (80,000 lbs - 120,000 lbs for non-divisible loads with a permit) should obtain an oversize load permit from the Quincy Public Works Department.

Quincy's permit process is designed to work in conjunction with state regulations, ensuring that oversize loads are routed through the city safely and with minimal disruption to local traffic. Loads exceeding these dimensions require special permitting and may need to follow specific routes designated by the City.

In Quincy, escort vehicles are required for oversize loads exceeding 14 feet 6 inches in width or 15 feet in height. Additionally, loads over 18 feet wide or 120 feet long require a pilot car escort.

For certain oversize loads, particularly those traveling on major routes like Hancock Street or Furnace Brook Parkway, a police escort may be required. Applicants should contact the Quincy Police Department's Traffic Division at (617) 376-0300 to arrange for an escort and understand the associated fees, which can range from $75 to $150 per hour per officer, plus administrative costs.

To apply for an oversize load permit in Quincy, applicants should visit the Quincy Public Works Department's website or contact them directly at (617) 376-1900. The application requires detailed information about the load, including its dimensions, weight, and proposed route through the city.

Documentation requirements include proof of insurance, a detailed route plan, and, for certain loads, structural analysis to ensure the safe transport of the oversize cargo. Applicants are advised to consult with the Quincy Public Works Department to ensure all necessary documentation is provided.

Quincy has specific time-of-day restrictions for oversize loads. Generally, oversize loads are not permitted during peak hours (7-9 am and 4-6 pm, Monday through Friday) unless special arrangements are made with the Quincy Public Works Department.

Seasonal restrictions may apply during periods of extreme weather, such as heavy snow or flooding, which can impact the city's infrastructure. Loads that could potentially damage city streets or infrastructure may be restricted during these times.

Certain routes, such as those through historic districts like the Quincy Historic District, may have additional restrictions or requirements for escorts and permits.

The base permit fee for an oversize load in Quincy is $50. Additional fees are applied based on the complexity of the route and the size of the load. For example, loads requiring a police escort incur the costs associated with the escort service, as mentioned earlier.

There may also be fees for any required damage bonds to protect city infrastructure. The total cost will be determined after the application is reviewed and the specific requirements for the load are assessed.
