ORIGINAL REPORT: Trying to get to a “heavy rescue” 911 call at 11th/Spokane (map), Harbor Island vicinity, we are stuck in a mess near the Delridge approach to the low bridge, and we see police on the low bridge. Stay away at all costs, it’s gridblock, even to try to turn west back onto W Marginal. UPDATE: Just heard it’s an overturned semi (photo above, added 9:20 am), so that’s why the low bridge is blocked before you get to the scene. Trying to get west onto West Marginal or SW Spokane back toward the rest of WS – the problem is a huge amount of diverted semitruck traffic trying to get up onto the high bridge the other way. Gridlock as a result. This city camera has a partial view of the backup west of the crash, Marginal/Chelan. ADDED 9:31 AM: Two of our pics taken as we came off Delridge into the jammed intersection at Delridge/Marginal/Spokane – police officer at blocked west end of low bridge, followed by the truck-dominated traffic viewed facing north.
Odd irony that today is the start of the Spokane Street work we’ve been reminding you about – and in fact we were about to head to check out the start of the detour, just as we got word of this – but that’s happening about a mile east, and this crash had NOTHING to do with it. Just heard on the radio that this may not be cleared until about 10:15; we’ll post updates as we get them. (Admiral and Fauntleroy approaches are obviously your better bet to get on the high bridge but with the low bridge out of commission, they’re likely slower too.) 9:45 AM UPDATE: Got a note from Hawk, who’s on a Route 21 Metro bus “that was re-routed all the way down to the 1st avenue bridge” – a reminder that this is affecting buses too. 9:52 AM UPDATE: Bike commuter Simon sent the following photo looking back westward toward the wreck scene, and notes that bicyclists/pedestrians are being allowed across the low bridge.
10:13 AM UPDATE: In comments, another West Seattle bike commuter, Aaron, says he saw the truck topple: “I watched this all go down, it was surreal. Not sure what caused the truck to lose balance, but as I was coming over the lower level bridge on my bike, the truck appeared to drop down off the curb, sway, and then ease over on its side. Driver was able to climb out and appeared unharmed.” 10:36 AM UPDATE: Just confirmed this with a drive through the area – the low bridge has reopened and the gridlock near the West Seattle-side approach has cleared.
