Seasonal Freight Patterns
How construction freight volume in Washington fluctuates throughout the year.
Construction freight in Washington follows the building season closely. Spring through fall represents peak demand as projects break ground and push toward completion. Seattle sees its highest construction material volumes from March through November. Winter months bring reduced activity in northern parts of Washington, though interior finishing work maintains some freight demand for fixtures and supplies. Highway and infrastructure projects funded by the Infrastructure Investment and Jobs Act have extended the season for heavy materials like aggregate and steel in Washington.
