The trail across the 520 Bridge will be closed from 11 p.m. Friday through 5 a.m. Monday along with all the traffic lanes and ramps. The Montlake Bridge and Montlake Boulevard will remain open for regular travel.

Kind of a bummer for the bridge to close for a summer weekend with such a spectacular forecast. But the project is getting closer to completion, though it sure feels like it will never end. The website still lists a 2024 completion date for the whole Montlake project. The unique walking and biking bridge over SR-520 that will connect from the bridge trail on the north side to the Arboretum could open in September, though no official date has been released yet.

More details on the closure from WSDOT:

SR 520 and the SR 520 Trail will be closed in both directions between I-5 and the Eastside from 11 p.m. on Friday, July 26 to 5 a.m. on Monday, July 29. To accommodate those leaving the Seafair Torchlight Parade, from 4:30 to 7:30 p.m. on Saturday, July 28, crews will open the northbound I-5 ramp to eastbound SR 520, one eastbound SR 520 lane from I-5 to the Eastside and the SR 520 eastbound off-ramp to Montlake Boulevard. Those attending the parade from the Eastside should find alternate routes and expect delays.
