1:53 PM: You might be seeing the engines and trucks and/or hearing the sirens – big Seattle Fire “heavy rescue” dispatch is headed to 16th SW/SW Lander on Harbor Island. Via scanner, the incident is described as an overturned semi-truck. Updates to come.

1:56 PM: Most of the units are being dismissed – no injuries. SDOT is being requested for cleanup of a fuel spill.

3:35 PM: We went over to Harbor Island within the past hour to see if the truck was still there. As you can see in our photo, added above, a tow truck had arrived to work on pulling the trailer upright. No traffic effects.
