All oversize loads entering the City of Alabaster, Shelby County, must conform to the requirements set by the Alabama Department of Transportation (ALDOT).

In general, any vehicle over 8 feet 6 inches in width, 13 feet 6 inches in height, and exceeding 80,000 lbs should obtain an oversize load permit from ALDOT and potentially coordinate with the City of Alabaster Public Works Department for local routes.

Specifically, any load traversing through downtown Alabaster near the Thompson High School area or utilizing Highway 31 requires careful route planning and may necessitate a pre-approved route from the City to minimize disruption during school hours.

Escort vehicles are generally required in Alabaster when the load exceeds 12 feet in width, 14 feet 6 inches in height, or 100 feet in length. Front and rear escorts may be necessary depending on the specific route and dimensions.

While ALDOT sets the escort standards, local police escorts might be required for specific routes, especially those impacting school zones or high-traffic areas. Contact the Alabaster Police Department's traffic division at (205) 663-7575 for scheduling and fee information. Expect a minimum of 48 hours' notice for police escorts.

Permits are primarily obtained through ALDOT's online permitting system. Visit their website (www.dot.state.al.us) for detailed instructions. For local route considerations within Alabaster, contact the Alabaster Public Works Department at (205) 664-6840.

Documentation requirements include vehicle registration, insurance, detailed load dimensions and weight, proposed route, and a certificate of liability insurance. For exceptionally heavy loads, a structural analysis of bridges along the route may be required by ALDOT.

Time-of-day restrictions may apply within Alabaster, particularly during peak commuting hours (7:00 AM - 9:00 AM and 4:00 PM - 6:00 PM) on weekdays. Avoid scheduling heavy haul transports during these times, especially near Highway 31 and Colonial Promenade Parkway.

Seasonal restrictions are generally limited to severe weather events. Monitor local news and weather forecasts for potential road closures or restrictions due to flooding or ice, particularly during the winter months.

Certain residential neighborhoods and areas around schools have restricted access. Avoid routes through the Old Town Alabaster area and near Thompson High School during school hours. Coordinate with the City of Alabaster for alternative routes.

ALDOT permit fees vary based on load dimensions, weight, and distance traveled. Base fees typically start around $25 and increase with load size and route complexity. Contact ALDOT for a precise quote.

Fees increase for loads exceeding standard dimensions or weight limits. Additional fees may apply for weekend or holiday travel. Local police escorts, if required, will incur additional hourly fees payable to the Alabaster Police Department.
