Estimating from aerial photos, the Port of Seattle stretches along about six miles of waterfront plus another five miles of the Duwamish River. It's got facilities for handling bulk cargo, containerized cargo, oil, and natural gas. It's got at least two cruise-line terminals, three public marinas, a number of sightseeing-cruise docks, one ferry dock (cars and passengers), at least one ro-ro dock for trains, a coast-guard station, facilities to handle things like airplane parts being shipped to Boeing, and I'm sure there's at least one fish-processing plant in there somewhere. There are at least two drydocks, support docks for various specialist ships, what looks like a gas station for freighters, and similar facilities. A modern industrial port is a very complicated place. -- Mark _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
