All oversize loads entering the City of Glendale Heights, located in DuPage County, must conform to the requirements set by the Illinois Department of Transportation (IDOT) and the Glendale Heights Public Works Department.

Generally, any vehicle exceeding 8 feet 6 inches in width, 13 feet 6 inches in height, and within the Class V weight classification (over 80,000 lbs) should obtain an oversize load permit from the Glendale Heights Public Works Department. Loads exceeding these dimensions or weight limits may require additional review and approvals.

Loads traversing Main Street (Illinois Route 53) within Glendale Heights may be subject to additional scrutiny due to its designation as a high-traffic commercial corridor. Coordination with the Village's Traffic Engineering Division is recommended to minimize disruptions.

Escort vehicles are typically required in Glendale Heights when the load exceeds 12 feet in width, 14 feet 6 inches in height, or 90 feet in length. These dimensions are subject to change based on specific route conditions and IDOT regulations.

Local police escorts may be required for exceptionally large or heavy loads, especially those traversing heavily populated areas or requiring lane closures. Fees for police escorts are determined by the Glendale Heights Police Department and are typically billed at an hourly rate per officer, with a minimum of four hours. Scheduling requires at least 72 hours advance notice.

To apply for an oversize load permit in Glendale Heights, contact the Public Works Department at (630) 260-6050 or visit the Village Hall at 300 Civic Center Plaza. Permit applications are also available for download on the Village's website under the 'Permits' section of the Public Works Department page.

Required documentation includes a detailed route plan, vehicle specifications, load dimensions and weight, certificate of insurance, and any relevant IDOT permits. A copy of the bill of lading may also be requested to verify the nature of the cargo.

Oversize loads are generally restricted from traveling through Glendale Heights during peak traffic hours, specifically between 7:00 AM and 9:00 AM, and between 4:00 PM and 6:00 PM, Monday through Friday. Exceptions may be granted on a case-by-case basis by the Public Works Director.

Seasonal weight restrictions may be in effect during the spring thaw (typically March and April) to protect roadways from damage. These restrictions are typically announced by IDOT and enforced by the Glendale Heights Police Department.

Certain residential streets and cul-de-sacs within Glendale Heights are strictly prohibited for oversize loads due to narrow roadways and turning limitations. These areas are clearly marked with signage, and alternative routes must be utilized. Contact the Public Works Department for approved route maps.

The base permit fee for an oversize load in Glendale Heights is $50.00. Additional charges may apply based on the size and weight of the load, the length of the route within the Village, and the need for traffic control measures.

Fees are assessed based on a combination of factors, including the load's width exceeding 10 feet, the total weight exceeding 100,000 lbs, and the requirement for lane closures or police escorts. Complex routes requiring significant coordination with Village staff may also incur additional fees.
