New Requirements for Worker Credentials in Port Areas May Impact Seattle Traffic

SEATTLE -Seattle drivers may encounter traffic backups on arterial streets near entries to several waterfront terminals at the beginning of the work week, on March 2 and 3. Seattle Department of Transportation (SDOT) traffic managers anticipate the terminal sites with the greatest potential for traffic impacts are:
  • Terminal 5 (in West Seattle off of SW Spokane Street),
  • Terminal 18 (Harbor Island off of SW Spokane Street), and
  • Terminal 46 (off of Alaskan Way S at S Atlantic Street).
Starting Saturday, February 28, the U S Coast Guard will begin enforcing federal requirements for new identification credentials for all truck drivers and other workers entering secured port areas. While the TWIC (Transportation Worker Identification Credentials) card requirement has been widely publicized, it is difficult to estimate how many drivers might arrive on Monday without the card.

Agencies and terminal operators have been working together for several months to prepare for these new regulations. SDOT Commercial Vehicle enforcement officers, Port of Seattle Police, and terminal managers will be partnering to minimize any traffic disruptions.

The Seattle Department of Transportation builds, maintains and operates Seattle's $12 billion transportation infrastructure. To further Mayor Nickels’ goal to get Seattle moving, the department manages short- and long-term investments in streets, bridges, pavement and trees, that better connect the city with the region.
