Beginning at 9 p.m. tonight (Friday), crews are scheduled to close the 520 Bridge, including the trail across Lake Washington. Montlake Boulevard and the underpass trail to the Arboretum will remain open.
More details from WSDOT:
Heads up, travelers: Crews will work around the clock this weekend to remove the old Montlake Boulevard overpass and support structures. This removal over SR 520 will make room to build a new crossing and highway interchange. Crews will begin closing roads and ramps on Friday night, Oct. 22 and reopen by 5 a.m. Monday, Oct. 25.
Please note, we originally planned to close Montlake Boulevard and the Montlake Bridge, but those roads will remain open this weekend. Check the Construction Corner as we fine tune the details for the moving parts of this weekend!
