The Municipality of Anchorage will impose seasonal weight restrictions on trucks starting April 20, 2026, at 8 a.m. to protect roads during spring breakup.

Trucks over 10,000 pounds will be limited to 75 percent of legal weight on paved streets and 50 percent on gravel, chip sealed, and recycled asphalt pavement roads. The restrictions typically last through May, depending on weather and ground temperatures.

Several major roads will keep full weight limits to maintain port traffic flow, including Ocean Dock Road from the railroad crossing to C Street, Whitney Road from C Street to Post Road, and portions of Third and Fourth avenues downtown.

Certain vehicles can operate at full legal weight during restrictions, including school buses, garbage trucks, milk tankers, heating oil delivery trucks, and vehicles carrying sealed interstate loads from the Port of Anchorage to their first destination.

Twenty-two specific streets will be posted with weight restriction signs, including Old Seward Highway from East 34th Avenue to Dowling Road, Arctic Boulevard from Northern Lights to Dimond Boulevard, and Lake Otis Parkway from Northern Lights to O'Malley Road.

For current information and a complete list of affected roads, visit muni.org or call the Traffic Department at 343-8406. The restrictions help prevent costly road damage when freeze-thaw cycles weaken pavement during spring breakup.
