Seattle

Seattle metropolitan area map showing all of the state routes and freeways (as of September 2011). The proposed path of the new Washington 99 tunnel is also shown. Work began on the Alaskan Way Viaduct Replacement Program in early 2011. Completion of the new alignment for SR 99 was initially slated for late 2015. It finally opened in February 2019.

Photographs of various boulevards and streets in Seattle.

Broad Street

Broad Street travels northeast from Alaskan Way at Belltown near Elliott Bay to Seattle Center and the Mercer Street connection with Interstate 5. The boulevard included an expressway section built in the 1950s between 5th Avenue N and 9th Avenue N. This changed with the Mercer Corridor Project, which revamped the South Lake Union street grid, focusing on Mercer Street as a six-lane boulevard toward Seattle Center from Interstate 5. Work included the removal of the below grade section of Broad Street from the Seattle Center area to Mercer Street at 8th Avenue N.
