1. Capitol Hill Station’s big red crane has been disassembled and the pieces trucked up to the Roosevelt Station construction site. Assembly has already begun during normal construction hours; however, Sound Transit will be adding a Sunday work day this weekend, on August 17, to put together the crane’s jib and hoist it into place.

Work will occur during daylight hours and start at 9 AM. And you should totally go check it out when it’s being hoisted because it’s gonna be something to see.

2. As soon as Monday, August 18, construction crews will start work installing a drainage line from the construction site to a sewer line in NE 67th Street. This project is expected to take up to three weeks, with work occurring between 8 AM-5 PM on weekdays.

Crews will work westward starting from just east of Roosevelt Way NE on NE 67th Street. Roosevelt Way will be reduced to one lane from 9 AM-3 PM for approximately two days during the first week of work.

Once the work has traveled to the west side of Roosevelt Way, the sidewalk and parking lane on the south side of NE 67th Street will be closed during work hours. Access to residents and businesses will be maintained, but minor delays during work hours should be expected.

The Northgate Link tunnel boring machines are not yet near the University of Washington campus, but a whole bunch of monitoring equipment is about to arrive.

Sound Transit will start installing equipment for 16 monitoring sites around the UW campus over the next couple months, starting here in August. The equipment will monitor the ground, utilities, and buildings located above the light rail alignment during tunneling on campus.

If you’re on campus during this work, here’s what you can expect:

  • Hours: Activities between 7 a.m. and 5 p.m.
  • Drilling Activities: Drilling into grass, asphalt or concrete, removing ground material and installing the monitor. Drilling will sound similar to a truck running with occasional hammering sounds. The vacuum truck will make noise while soil material is being removed (during the first few feet of drilling at each location). Drill rigs and support equipment may be temporarily stationed on streets or parking lots overnight during this work.
  • Equipment: Drill rig, trucks, traffic signage and cones, vaccum trucks, ladders
  • Access: Pedestrian, bicyclist, and motorist traffic will be maintained. Some locations may require temporary lane or sidewalk closures. There may also be impacts to street parking. Traffic cones, No Parking signage, roadway signage, and flaggers may be used when travel lanes or parking areas are affected during this work.
  • Stickers on buildings: Building monitoring stickers, called structural settlement points, are 3″x3″ stickers that crews affix to the outside of buildings and check regularly for any movement.

Between the U District Station up on Brooklyn and the University of Washington Station down on Montlake, nearly one mile of tunnel will pass under the university’s campus. TBMs are expected to arrive at the U District Station in late 2015.
