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

1. Continue digging for the underground light rail station

Activities include:

  • Removing dirt and materials using bulldozers
  • Installing wood planks or "lagging" between the vertical metal piles
  • Installing large pipes called struts across the top of the box spanning from east to west
  • Drilling cable tie-backs and installing soil nails to hold the walls during excavation activities
  • Hauling dirt and materials offsite using Brooklyn Avenue Northeast

Crews will dig until they reach about 95 feet below ground. Excavation will be ongoing through spring 2015.

2. Continue building the temporary bridge along Northeast 43rd Street

Activities include:

  • Delivering a crane to the project site
  • Building wooden forms and installing metal rebar
  • Pouring concrete into the wooden forms
  • Delivering and placing nine, 30-foot-long metal bridge girders to form the base of the bridge
  • Delivering and placing concrete panels onto the bridge girders

Northeast 43rd Street is expected to re-open to one-way traffic in spring 2015. The roadway is currently open to local traffic between the alley and University Way Northeast, the "Ave."

3. Continue install electrical utilities to power construction activities

Activities include:

  • Building wooden forms for the electrical utility vault
  • Pouring concrete for the walls and roof of the electrical utility vault
  • Installing electrical and mechanical systems

Other project-related activities include surveying and the installation of ground monitors above the future light rail tunnels.

Construction impacts:

  • Closure of Northeast 43rd Street between Brooklyn Avenue Northeast and the alley to motorists until early 2015.
  • Cranes and equipment located close to the sidewalk along Northeast 43rd Street.
  • Temporary short-term closures of Northeast 43rd Street just west of the "Ave" to deliver girders and concrete panels during bridge construction.
  • Construction vehicles parked on Northeast 43rd Street during the pouring of concrete and delivery of materials during bridge construction.
  • Temporary short-term closure of the northern end of the alley just east of 12th Avenue Northeast during the pouring of concrete for the electrical utility vault.
  • Noise from drilling the soil nails during excavation and other construction activities.
  • 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, 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.
