The locations for the work listed below are shown on the map. 

Pedestrian pathway is complete 
The pedestrian pathway between NE 43rd Street and Brooklyn Avenue NE is complete. Pathway hours are Monday through Friday, 7 a.m. to 6 p.m. The pathway is closed during evenings and weekends. 
Ways to get around construction when the pathway is closed:

  • 12th Avenue NE to NE 42nd Street or NE 45th Street
  • Brooklyn Avenue NE to NE 42nd Street or NE 43rd Street
  • University Way NE to NE 42nd Street or NE 45th Street 

End in sight for drilling activities along NE 43rd Street 
We have completed drilling for the north, west, and east shoring walls. The south shoring wall along NE 43rd Street is over 75% complete. We expect drilling to be completed for the shoring walls by the end of August.  

Digging begins for station excavation 
Crews have begun excavating on the north end of the site. Bulldozers are removing dirt and materials from the light rail station box. The materials are placed into trucks and hauled offsite using Brooklyn Avenue NE. 

As crews dig down, they will install long nails, called tie-backs, into the soil to secure the underground station walls. Crews will also be installing long metal beams, called struts and wales, across the top and sides of the box. These braces hold the soil during station excavation. Crews will dig until they reach about 95 feet below ground. Excavation will be ongoing through spring 2015. 

Construction impacts:

  • Closure of NE 43rd Street between Brooklyn Avenue NE and the alley to motorists until early 2015. NE 43rd Street between the alley and University Way NE is open for local traffic and businesses are open.
  • Two drill rigs working concurrently on drilling for the shoring walls.
  • Drill rigs and support equipment located close to the sidewalk along NE 43rd Street.
  • Scaffolding/temporary walkway enclosure along NE 43rd Street during drilling.
  • Noise from drill rigs during soil removal and installation of metal beams.
  • Noise from drilling the soil nails during excavation.
  • Potential low-frequency vibration during drilling.
  • Dust from soil removal and pouring of concrete.
  • 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.
  • 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.

Equipment: bulldozers, dump trucks, concrete trucks, vacuum trucks, excavators, jackhammers, drill rigs, cranes, generators, water treatment systems, street sweepers 

Schedule: Work hours are typically Monday through Friday from 7 a.m. to 7 p.m.  Intermittent weekend and evening work may be scheduled. Construction schedules are subject to change. Notifications will be distributed for significant changes.
