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.
Mode: Link light rail
Opens for service: 2021
Rider projection: Approximately 12,000 daily riders will board at U District Station by 2030
Ride times (average): U District to Westlake, 8 minutes
U District to Sea-Tac Airport, 41 minutes
U District to Northgate Station, 5 minutes
Project phase: Design & construction
Station: Cut and cover
Tunnels: Tunnel boring machines excavate and build northbound and southbound train tunnels
Funding partners: Federal grants, motor vehicle excise tax (MVET) and local sales tax
Sound Transit will refine the design of the station in 2014-2015. The next stage, called 90 percent design, will be presented to the public in mid-2015.
- Station platform will be about 80 feet below ground
- Two station entrances: one adjacent to the Neptune Theatre on Brooklyn Ave NE and the other at NE 43rd Street and Brooklyn Ave NE
- Elevators, escalators and stairs at each entrance
- Ticket vending machines
- Covered bicycle storage (approximately 100 spaces)
- Public art
The 90 percent design will include details about:
- Station architectural features
- Pedestrian, bicycle and bus connections
- Station construction schedule and method
- Redevelopment opportunities above the station
- Permanent public art
- Expect night and weekend work this summer. The City of Seattle Department of Planning and Development activated the Major Public Project Construction Variance for U District Station on June 22. This allows crews to work on tunneling support activities during the overnight hours.
- No high impact noise activities are allowed under this variance before 8 a.m. or after 5 p.m. on weekdays or before 9 a.m. or after 5 p.m. on weekends and holidays.
Activities this summer include:
- Pouring concrete at the bottom of the station box. This includes a base layer for the permanent station and a temporary layer to support the tunnel boring machines move across the station box.
- Preparing the ground surface for the TBMs arrival. This includes installing ground freezing pipes into the soil directly above where the TBMs will enter and exit the station box (located approximately 80 feet below ground). Ground freezing will take approximately six weeks
- Installing a turnaround area on Brooklyn Avenue NE just south of NE 45th Street. The turnaround will allow for 3-minute loading/unloading adjacent to UW Tower. The turnaround will remain in place until Brooklyn Avenue NE is restored to its permanent condition before the station opens in 2021. No parking is available in the turnaround area.
- Surveying and installing ground and building monitors above the future light rail tunnels.
- BM Brenda is currently between Roosevelt and U District Station. Brenda is expected to arrive at U District Station by early fall. TBM Pamela is expected to arrive later in 2015. Both machines are working their way from Maple Leaf south to the future University of Washington Station.
What to expect:
- Survey crews on sidewalks and roadways near the site and above the future tunnels.
- Frequent truck traffic on area roads delivering materials and hauling materials offsite. The number of trucks will decrease once excavation of the station is complete.
- Trucks and equipment arriving onsite during the early morning hours.
- Concrete trucks and other construction equipment entering the site using Northeast 43rd Street.
- Noise from equipment and heavy machinery.
- Wheel washing stations to minimize truck debris track-out onto city streets.
Equipment: drill rigs, bulldozers, dump trucks, concrete trucks, vacuum trucks, 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 (complete)
- 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 (underway)
- 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.
Temporary art during construction
Sound Transit plans to keep neighborhoods active and interesting during construction. That includes launching a temporary art program for the construction sites in the U-District, Roosevelt and Maple Leaf/Northgate neighborhoods.
D.K. Pan is lead artist for the U District Temporary Art Project.
