UPDATE 10/23 8pm: The trail has reopened.
The 520 Trail across Lake Washington will be closed starting at 11 p.m. tonight (Friday) until 5 a.m. Monday morning. I suppose the silver lining here is that this time the closure is for construction of the future biking and walking bridge, which will some day be quite nice after all these years of construction headaches.
Details from WSDOT:
Westbound SR 520 and its associated ramps will close between 92nd Avenue Northeast on the Eastside and I-5 in Seattle from 11 p.m. Friday, Oct. 21 to 5 a.m. Monday, Oct. 24. During these hours, crews will drill shafts for the highway lid and the pedestrian and bicycle bridge we’re building in Seattle’s Montlake neighborhood. The SR 520 Trail across the lake also will close over the coming weekend.
