SEATTLE – Broad Street in Seattle is now permanently cloased between 5th Avenue N. and 9th Avenue N and Mercer Street has been turned into a two-lane road between Queen Anne Avenue N. and 9th Avenue N.
The closure of Broad Street is part of the ongoing Mercer Corridor project and the Alaskan Way Viaduct replacement, and could cause slow traffic in the area. Drivers are encouraged to use alternate routes.
Closing this stretch of Broad Street will be used to widen Mercer Street. When completed Mercer will have three lanes of traffic driving in each direction between Interstate 5 and 5th Avenue North.
Other changes to this area:
• Access to Seattle Center and Queen Anne will be a direct route via westbound Mercer Street from I-5.
• Roy Street will have one lane in each direction between Queen Anne Avenue N and Fifth Avenue N.
• Queen Anne Avenue N will have one northbound lane and two southbound lanes between Roy and Mercer Streets.
• Left turns from westbound Mercer Street onto southbound Fifth Avenue N will be available.
• Left turns from eastbound Mercer Street onto northbound Dexter Avenue N will not be allowed for approximately one year.
• Access to northbound SR 99 from eastbound Mercer Street will be via southbound Dexter Avenue N onto westbound Thomas Street.
