UPDATES & INFORMATION
SIXTH STREET TRAFFIC SIGNALS
Update (March 4, 2019) -- Shoreline Construction’s crews are preparing this week for an intensive technique known as “pipe-bursting,” a trenchless process that will allow contracted workers to upgrade the sewer main beneath Sixth Street South, between Northeast 68th Street and the Google campus, without digging an open trench.
Shoreline Construction will, however, be digging trenches this week for eight side-sewers, as well as the pits for three of the five manholes it will be replacing during the next two weeks between Ninth Avenue South and Northeast 68th Street. All of this construction will take place between 7 p.m. to 5 a.m. The City of Kirkland is thanking nearby residents for their on-going patience.
The night schedule is important for two reasons: It expedites Shoreline Construction’s rate of work by allowing crews to work while few vehicles are on the road and, even more importantly, it allows crews to replace a section of sewer pipe that conveys sewage from businesses while they are closed.
This work will continue at night for the next five weeks.
During the day on Tuesday, Wednesday and Thursday this week, Shoreline Construction is resurfacing a section of Sixth Street South between Northeast 68th Street and Fifth Avenue South. That process will require flaggers to direct traffic around closed lanes.

: A project aimed at managing Sixth Street South’s traffic congestion with a pair of four-way traffic signals should be complete by March 2019. Johansen Construction's crews will install traffic signals in February 2019 at Sixth Street South’s intersections with Kirkland Way and Ninth Avenue South. At Sixth Street and Kirkland Way, Johansen Construction reconfigured the intersection to better accommodate buses’ turning-radii and reconstructed it with concrete. Concrete is more durable than asphalt pavement and thus, more capable of withstanding the heavier-than-normal traffic loads buses impose on the intersection’s surface.
Project engineers expect the signal poles to be on-site in early February and to be installed by mid-March.
: A City of Kirkland contractor is upgrading the five-decade-old cast iron and concrete water and concrete sewer mains that run beneath Sixth Street. Shoreline Construction is upgrading more than 2,200 linear feet of eight-inch water main between Northeast 68th Street and Fifth Avenue South and more than 1,000 feet of sewer main between Northeast 68th Street and Eighth Avenue South.
WHEN: Construction will continue into April 2019. Shoreline Construction’s crews will mostly be working during the day for eight hours between 7 a.m. and 6 p.m. While installing some segments of the new water main, however, they will, at times, be working between 7 p.m. and 5 a.m.
WHAT TO EXPECT: Shoreline Construction will be digging a trench to install the water main along the east side of Sixth Street. To install the sewer main, the contractor will be using a technique known as “pipe-bursting,” which reduces traffic impacts and material waste. Crews will cover any open trench after each work day.
PAVING SIXTH STREET: The last of these projects will be to repave Sixth Street South, which Kirkland's overlay program will do after it has upgraded the Sixth Street water main, between Fifth Avenue and Northeast 68th Street as well as the sewer main between Eighth Avenue South and Northeast 68th Street.
WHY ALL THE FOCUS ON SIXTH STREET?: These four projects are part of a long-term effort to prepare the Everest and Houghton neighborhoods for the public's increasing use of Sixth Street. Along with the Cross Kirkland Corridor, these projects provide for all primary transportation modes: walking, bicycling, driving and riding transit. They also ensure that residents continue to have access to clean drinking water and sewage treatment. The thumbnail on the right links to a map that illustrates these projects.
