Washington State Route 99
Encyclopedia
State Route 99, abbreviated SR 99, commonly called Highway 99, is a numbered state highway
in the U.S. state
of Washington extending just under 50 miles (80.5 km) from Fife
in the south to Everett
in the north, with a 2 miles (3.2 km) gap in Tukwila
.
, near its own intersection with 54th Avenue E. From there, it heads eastward to Federal Way
where it becomes Pacific Highway South and intersects SR 18
just west of its interchange with I-5. It then begins to travel north, through Des Moines
, overlapping SR 509
for a few miles. The route becomes a little difficult to identify for several miles, as there are no reassurance signs until entering SeaTac
. Once there, it becomes International Boulevard and forms the eastern boundary of the Seattle-Tacoma International Airport
until crossing SR 518
, where the southern division ends.
The northern division begins where the freeway carrying SR 599 northward passes over International Boulevard South. SR 599 terminates at that point; north of there, it becomes SR 99. SR 99 continues north to an interchange with SR 509 and West Marginal Way at the southern end of the First Avenue South Bridge
. SR 99 crosses over the bridge and onto East Marginal Way, a surface street passing through the industrial and warehouse district of south Seattle known as Sodo
. Near Spokane Street and the eastern end of the West Seattle Bridge
, SR 99 again becomes a freeway. A portion travels on the surface before the route rises onto the Alaskan Way Viaduct
, which traverses the downtown Seattle waterfront. The viaduct terminates at the Battery Street Tunnel, which runs for 3140 feet (957.1 m) underneath Battery Street. The tunnel carries SR 99 underneath the Belltown neighborhood of Seattle and onto Aurora Avenue North.
The tunnel was built in 1952 using the cut-and-cover method. It carries two traffic lanes in each direction, and connects the Alaskan Way Viaduct
to Aurora Avenue N., providing continuity for State Route 99. There are no sidewalks or other provisions for pedestrians or bicyclists in the Tunnel. When an incident blocking traffic takes place within the tunnel, warning lights advise motorists to exit SR-99 at Western Avenue (northbound) and Denny Way (southbound). Emergency exits are placed behind sliding doors, with stairways leading up to Battery Street on the surface. Plans to renovate the Battery Street Tunnel to meet current ventilation and safety standards are on hold as of August 2008 due to financial and other considerations.
Aurora Avenue at this point is lined with businesses, residences, side streets and sidewalks. There is a median barrier, so cross traffic and left turns are not available; access is right-in/right-out
(RIRO) only. There are also several pedestrian overpasses and underpasses along this route. As Aurora Avenue nears and passes along the east flank of Queen Anne Hill
, the median barrier ends, although access remains RIRO. Aurora Avenue then crosses the Lake Washington Ship Canal
on the George Washington Memorial Bridge
(1932). At the interchange for Bridge Way, a very low median barrier begins, rising to a higher wall a bit north of North 38th Street. The barrier lowers again just beyond North 49th Street. Aurora Avenue then bisects Woodland Park
, with the barrier replaced by paint stripes until the next side street, North 59th. The higher wall resumes as Aurora Avenue approaches the northbound entrance from Green Lake Way. Just north of North 68th Street, there is a traffic light-controlled crosswalk across Aurora Avenue through a narrow break in the median. RIRO access ends and cross traffic resumes just before Winona Avenue North, which is the first traffic light-controlled intersection on Aurora Avenue. Aurora Avenue continues northward to 145th Street, which intersection is also the west terminus of SR 523. At that point, SR 99 leaves Seattle and enters Shoreline
as it continues northward on Aurora Avenue. SR 99 and Aurora Avenue crosses a former Interurban
Railway right-of-way, now an urban trail, near North 155th Street. It then continues north to the King County
- Snohomish County
line, which consists of a street marked North 205th Street in King County and 244th Street Southwest in Snohomish County.
Upon entering Snohomish County
and the city of Edmonds
, the highway changes names to Pacific Highway North and crosses interchange with SR 104. The highway continues north into Edmonds.
North of Edmonds, SR 99 enters Lynnwood
, where it is known as Highway 99. SR 99 intersects SR 524 at 196th Street Southwest. SR 99 intersects SR 525 (known as the Mukilteo Speedway) at a partial interchange near Serene Lake. This interchange marks the northern end of the SR 525 freeway, which is an extension of Interstate 405
.
After a journey through Lynnwood, SR 99 enters Everett
, where it becomes known as Evergreen Way, until 3 miles (4.8 km) south of its terminus. At an intersection of Evergreen Way and Everett Mall Way, SR 99 goes northeast on Everett Mall Way. SR 99 passes the Mall near its interchange/intersection with Interstate 5, SR 526, and SR 527.
Before the completion of Interstate 5, SR 99 used to follow Evergreen Way onto Everett Mall Way (then known as "The Broadway Cut-Off") to Broadway; it then continued northbound through downtown Everett on Broadway. As Evergreen Way continues north in Everett, it becomes Rucker Avenue just south of 41st Street. Rucker Avenue intersects the former alignment of SR 526 at 41st Street.
Near the northern terminus of the Alaskan Way Viaduct
, the southbound section of the viaduct is cut away to make room for a brick building that was there at the time of construction. This provides an interesting visual; although the structure of the building extends only a few inches into the viaduct, it is nonetheless unusual to see part of a building in the road, on a bridge, 50 ft (15.2 m) in the air.

in Blaine, Wa. to Vancouver, Wa. at the Oregon Border. SR 99 is primarily the route of US 99 where building Interstate 5 along the same route would have been prohibitively expensive, or would not have served the greater good. Also, with the exception of the freeway sections, and from the Battery Street Tunnel to the north side of the George Washington Bridge (Aurora Bridge), SR 99 is tightly lined with stores, making any expansion nearly impossible. - SR 99 used to be both US 99 and Primary State Highway (PSH) 1. As I-5 was built, these designations were moved to the new alignments from state line to international border until I-5 began being designated over the route. They were then co-signed briefly, and later, around the time of the 1964 state highway renumbering1964 state highway renumbering (Washington)In 1963, a law was passed authorizing a new numbering for sign routes. In 1970 the legislative definitions were changed to use the sign route numbers but renamed state routes...
, SR 99 was redesignated over much of its former route. Slowly, over time, SR 99 was cut back to the current routing from Fife to Everett. - US 99 originally was routed through the downtown Seattle streets, along 1st Avenue and 1st Avenue South. When the viaduct was built and US 99 was transferred to it, the old route became U.S. Route 99 Alternate (later Business).

However, shortly after the opening of the Boeing Freeway and the Everett MallEverett MallEverett Mall is a indoor/outdoor shopping mall located in Everett, Washington, USA.

Some other connection may be made when the viaduct is replaced in the near future. - Many cities and towns along the I-5 corridor in Washington have streets named 'Highway 99', 'Old Highway 99', 'Pacific Highway', or simply 'Old 99' all used to be part of US 99. Those cities with the streets still designated 'Highway 99' can cause confusion with people unfamiliar with the area, as they expect the street to be part of SR 99.
