U District Station
This station is located on Brooklyn Ave NE between NE 45th and NE 43rd streets. It will serve the surrounding residential community, the "Ave" business district, other employment sites, the UW Tower and the north University of Washington campus.
Riders will board trains underground. The station will have two entrances along Brooklyn Ave NE with elevators, escalators and stairs. The station will have about 100 bike parking spaces. The site is designed to accommodate future development above the station. This station was known as "Brooklyn Station" during earlier planning stages. Its official name is now U District Station. Sound Transit's policy on naming facilities is available online.
When the station opens, riders will be able to travel to the airport in 41 minutes and to Northgate in about 5 minutes.
Expect night and weekend work this spring. Work hours will typically be Monday through Friday from 7 a.m. to 10 p.m. and Saturday from 9 a.m. to 10 p.m. Intermittent Sunday work may be scheduled. Construction schedules are subject to change.
Bulldozers are removing dirt and materials from the light rail station box. Over 135,000 cubic yards of soil will be removed from the site (equates to over 40 Olympic size swimming pools). Crews will dig until they reach about 95 feet below ground.
As of April 2015, approximately 75 percent (or 95,000 cubic yards) of soil has been excavated. Excavation will be ongoing through summer 2015.
Activities this spring include:
- Excavating dirt and materials from the station box
- Installing wood planks or "lagging" between the vertical metal piles
- Drilling for tie-backs and soil nails to hold the station walls during excavation
- Installing rebar and concrete on the east wall
- Hauling materials offsite using Brooklyn Avenue Northeast
- Stabilizing the soil in advance of the tunnel boring machine's arrival (anticipated fall 2015)
- Pouring concrete at the base of the light rail station box
Other project-related activities include surveying and installing ground and building monitors above the future light rail tunnels.
What to expect:
- Frequent truck traffic on area roads and on the project site delivering materials and hauling materials offsite. Expect an average of four trucks per hour during excavation (daytime hours).
- Concrete trucks and other construction equipment entering the site using Northeast 43rd Street.
- Noise during drilling for cable tie-backs and soil nails during excavation.
- Noise from equipment and heavy machinery.
- Dust from soil removal and pouring of concrete.
- Wheel washing stations to minimize truck debris track-out onto city streets.
Equipment: drill rigs, bulldozers, dump trucks, concrete trucks, vacuum trucks, excavators, jackhammers, cranes, conveyor system, generators, water treatment systems, street sweepers
Crews will work to minimize impacts, such as noise, dust, debris, and access impacts during the work.
Construction of the Northgate Link Extension began in fall 2012.
Sound Transit light rail station construction requires closing Brooklyn Ave NE between NE 43rd and NE 45th streets to traffic and pedestrians from 2013-2020. NE 43rd Street between Brooklyn Ave NE and the alley west of University Way NE will be closed to motorists from spring 2014 - winter 2015.
Sound Transit is maintaining access for pedestrians and bicyclists along NE 43rd Street at Brooklyn Ave NE. A pathway adjacent to Varsity Arms condos is open 7 a.m. to 6 p.m., Monday through Friday (except holidays).
Demolition and initial activities, early 2013 (complete)
- Remove hazardous materials from buildings prior to demolition.
- Demolish and remove existing buildings at the future station site.
- Salvage and recycle demolition materials. Sound Transit's sustainability goals include salvaging, reusing and recycling a minimum of 75 percent of demolition materials.
Utility relocation, early 2013 - mid 2014 (underway)
- Sound Transit, Seattle City Light, Puget Sound Energy and communications companies relocated overhead power lines, phone lines and internet lines.
- Relocating underground gas, water, stormwater and power lines.
Station excavation, mid 2014 - early 2015 (underway)
- Build a construction wall around the site to reduce dust and noise.
- Install soil retention walls to support excavation activities.
- Open a new pedestrian pathway adjacent to Varsity Arms condos.
- Excavate the underground light rail station to a depth of 95 feet.
- Pour a concrete surface to support the tunnel boring machines and support equipment.
Tunnel construction, late 2015- early 2017
- Bore the tunnels. Tunneling began at Maple Leaf Portal. The tunnel boring machines are heading south to Roosevelt Station, then U District Station and then to the University of Washington Station at Husky Stadium.
- Dig cross-passages for safety. Cross passages are small, person-sized tunnels that connect the north and southbound train tunnels.
- Nighttime noise variance applies during tunnel construction.
Station construction, late 2017 - mid 2020
- Build the station, including floors, stairs, mezzanines, elevators and the above ground entrances.
- Restore landscaping, streets and sidewalks.
- Reopen Brooklyn Ave NE between NE 45th and NE 43rd streets.
Systems installation and testing, late 2018 - late 2020
- Install rails and communications, electrical, emergency and other systems in the tunnels and stations.
- Test systems and test-run light rail trains.
