Seattle Freight Mobility Program
The Seattle Department of Transportation (SDOT) maintains a freight program to improve freight mobility and safety in Seattle, in conjunction with department efforts to improve mobility across a range of transportation modal opportunities for moving people and goods. Assigned staff actively work on plans, programs and implementation of measures to ensure the safe and efficient movement of goods and services. SDOT has staff supporting freight mobility in the categories of commercial vehicle enforcement, planning, traffic operations, capital project implementation and funding resources. SDOT also maintains the Seattle Freight Advisory Board to obtain timely freight stakeholder input and recommendations on Seattle’s and external agencies proposed plans and improvements. SDOT staff participate in regional stakeholder and planning forums concerned with fostering advances in freight mobility.
All over-legal loads traveling within the City of Seattle are required to obtain a special permit. See this link for more information.

Freight Program Mailing Address:
Seattle City Council adopted Resolution Number 31243 in September, 2010 expressing the intent to create a more formal advisory body for freight issues by establishing a Freight Advisory Board. This new Board will advise the Mayor, the City Council, and all departments and offices of the city in the development of a functional and efficient freight system, and on all matters related to freight and the impact that actions by the city may have on the freight environment. The Board replaced the Freight Mobility Advisory Committee upon its formation in January 2011.
The City of Seattle established the Freight Mobility Advisory Committee (FMAC) in September 2002 to advise elected officials, SDOT and other agencies on measures to improve freight mobility and safety in Seattle. The Committee served for eight years through December 2010, and was replaced in early 2011 by the new Freight Advisory Board.
