U District Station

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.

 

Current construction activities (Winter 2015)

  • Digging. Bulldozers are removing dirt and materials from the light rail station box. As crews dig down, wood planks or "lagging" are being installed between the piles to form the underground station walls. Crews are using three types of devices to secure the walls: struts, cable tie-backs, and soil nails. The most visible supports are large pipes (3 to 3.5 feet in diameter) called struts. The struts span the station from east to west. The contractor will also drill horizontal holes between 50 and 120 feet long into the soil and install long cables, called tie-backs, into the holes and grout them in place. In select locations, crews will drill 40- to 45-foot long rods, called soil nails, into the soil to hold the station walls.

    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 December 2014, approximately 40 percent (or 50,000 cubic yards) of soil has been excavated. Excavation will be ongoing through spring 2015.
  • Roadwork. Crews will be repaving sections of Brooklyn Avenue Northeast and Northeast 43rd Street to create a seamless transition for motorists between the new roadway bridge and adjacent roadways. This work is weather dependent. Northeast 43rd Street is anticipated to re-open to one-way traffic between Brooklyn Avenue Northeast and the alley just west of the Ave by early spring 2015.
  • Utility work. Crews are installing electrical utilities within the project construction site near the intersection of Northeast 43rd Street and 12th Avenue Northeast. The utilities will provide power for construction activities. Near-term activities include installing electrical and mechanical systems. 

What to expect:

Access/travel

  • Closure of Northeast 43rd Street between Brooklyn Avenue Northeast and the alley to motorists until spring 2015.
  • Pedestrian detour near the intersection of Northeast 43rd Street and Brooklyn Avenue Northeast during sidewalk work.
  • Closure of the alley at Northeast 43rd Street during daytime work hours (typically 7 am to 7 pm) during roadway work. A section of Northeast 43rd Street just west of University Way Northeast, the "Ave," will be open for local business deliveries. Road work will not impact Brooklyn Avenue Northeast access to U Manor garage or the UDPA parking lot.
  • Intermittent parking and access impacts along Northeast 43rd Street during daytime work hours.
  • 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).
  • Trucks delivering large loads during the early morning hours.

Noise

  • Noise from breaking up and removing existing asphalt and materials along Northeast 43rd Street and Brooklyn Avenue Northeast.
  • Noise and low-level vibration during drilling of cable tie-backs and soil nails during excavation.

Dust-debris

  • Dust from soil removal and pouring of concrete.
  • Wheel washing stations to minimize truck debris track-out onto city streets.

Crews will work to minimize impacts, such as noise, dust, debris, and access impacts during the work.

Construction overview

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 will begin at Maple Leaf Portal and head 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.
