NOAA will bring two large vessels through the swing bridge this afternoon, according to SDOT at approximately 5:30 PM, but they could arrive ten or fifteen minutes earlier. It is expected that the openings will last in the 25-30 minute range.
Delays to motor vehicle and bicycle traffic along the corridor are expected.
Travelers are advised to use alternate routes to West Seattle. Variable message signs are being deployed to alert the traveling public and King County Metro Transit has been notified of the opening.
