Congestion expected; access maintained to downtown, Seattle Center
SEATTLE – Drivers face increased congestion for the next six weeks on southbound State Route 99/Aurora Avenue North approaching downtown Seattle. Anticipated backups begin March 6 when crews building the SR 99 tunnel narrow southbound Aurora from three lanes to two between Republican and John streets, just north of the Battery Street Tunnel.
The lane closure is scheduled to last through at least mid-April and will give crews space to relocate utilities buried up to 15 feet beneath the westernmost lane of the roadway. Relocating the utilities will allow crews to begin building the SR 99 tunnel’s north portal, which will be located near Harrison Street between Sixth Avenue North and Aurora.
Approximately 31,000 vehicles use this stretch of southbound Aurora each day, with the heaviest traffic volumes during the morning and afternoon commutes. The southbound exits at Broad Street and Denny Way will remain open, maintaining vital connections to the neighborhood as the community prepares to host a series of events celebrating the 50th anniversary of the Seattle World’s Fair.
“This is a busy time for Seattle Center and the surrounding neighborhood, and we are doing everything we can to keep traffic moving through the area,” said Linea Laird, WSDOT Administrator for the Alaskan Way Viaduct Replacement Program. “Drivers will have access to businesses, residences and events throughout construction.”
Drivers will use Broad Street and Denny Way to reach businesses on Republican, Harrison, Thomas and John streets while the southbound lane on Aurora Avenue North is closed for construction.

Also, buses will not stop along the detour route with two exceptions – they will stop on Fifth Avenue North at both Mercer and John streets.
