10:31 PM: For the second time today, a tree is reported to have fallen across the southbound – uphill – lanes of the Highland Park Way hill. Police are on the scene now and telling dispatch they have to close the entire SB side of the hill. Dispatch says SDOT is not able to immediately respond, so this closure might last a while.

10:38 PM: Police say they’ve had to close one northound lane too because it’s a “big tree.”

11:31 PM: Thanks to Kay for the update in comments, pointing out this is actually across the downhill lanes despite what the original radio exchanges said. Also, above is a screenshot from one of the SDOT cameras nearby.

MIDNIGHT: They’re still working on it. And Kay also points out that this is blocking the pedestrian path too.

12:57 AM: Live camera shows all lanes of the street back open.
