Sometime today, Thursday, July 31, TBM Brenda will have chewed her way through 500 feet of Maple Leaf soil on her way south to Roosevelt Station. Another TBM now being assembled at the Maple Leaf Portal will start carving the southbound light rail tunnel sometime in October.

I’m guessing Brenda is a bit dirtier these days.

Roosevelt Station news

Station box wall construction now complete, the main work at the Roosevelt Station construction site is now the *excavation* of said station box. Crews are digging down about four feet at a time, removing soil from the station box area, pausing to stabilize the station walls that have been newly revealed, and then digging some more.

The station box needs to be fully excavated by the time Brenda arrives, sometime in early 2015.

And now for some NE 65th Street detour news:

In mid to late August, drivers heading past the Roosevelt Station site on NE 65th Street during the day may be detoured due to a project to install water lines under the road at the intersection of NE 65th Street and 12th Avenue NE. The signed detours will be in place from 7 a.m. to 3 p.m. weekdays. Westbound drivers can expect detours via 12th Avenue NE, NE 70th Street and Roosevelt Way NE and eastbound drivers can expect detours via 12th Avenue NE, NE 75th Street and 15th Avenue NE. Only one direction of travel will be detoured at a time.

These detours combined with the work on the Rooster Apartments on the west side of Roosevelt Way NE are making travel on NE 65th Street through the Roosevelt neighborhood a pain for all concerned (drivers, pedestrians, cyclists, etc.). We urge all travelers in the area to have some patience and practice grace-filled egress in the area.

U District Station News

This week, crews are digging holes in which to place piles that will make up the southern wall of the station: 76 holes, each between 50 to 105 feet deep. To help speed this work along, crews are now on site on Saturdays AND using two drill rigs.

NE 43rd Street east of Brooklyn Avenue NE is still closed to motorists, but what are you doing driving around in that area anyway it is a mess.

If you’re sitting near internet and wondering how construction is doing at any of the above locations, there’s a webcam (or three) for that:

Each page also has a “Stream Time-Lapse Movie” button on the left-hand side, for those who appreciate more action than a live shot once every 15 minutes.

20140731_SaturdayConcretePourUPDATE (2:17 PM): Just into the Ravenna Blog inbox is a Roosevelt Station construction alert for Saturday.

Saturday morning concrete pour at Roosevelt Station construction site

On Saturday, Aug. 2, construction crews working for Sound Transit will begin work at 7 a.m. for a concrete pour. Residents may notice noise from truck engines.

Crews will do everything within reason to keep noise to a minimum.

Why is this concrete pour happening on Saturday?

High demand for concrete resulted in limited schedule availability for the concrete pour at Roosevelt Station. Doing the work on Saturday morning will help keep the project on schedule by at least two weeks.
