Moving Lines For Station Construction, Providing Power To The Tunnel Boring Machine
Building the Roosevelt Station and powering the machine to drill the tunnel to the Maple Leaf Portal is a little like planting a garden. Much as the soil must be worked ahead of planting seeds, electrical relocations need to take place before anything else happens.
Here is an approximate timeline. See the maps on the right.
Ahead of the roosevelt station construction:
Rebuild of duct bank and vaults to serve Dwell Condominiums and Roosevelt Apartments-start
(April, 2013) to completion date (May, 2013).
Installation of overhead power lines on 12th Avenue NE, NE 65th Street, and Roosevelt Way NE. Estimated start (April, 2013.) to completion date (May, 2013).
Removal of existing overhead 26kV power lines and poles over station excavation along NE 66th & 67th streets. Estimated start (May, 2013) to completion date (June, 2013).
Removal of existing overhead lines on the north side of NE 65th & west side of 12th Avenue NE. Estimated start (April, 2013) to completion date (June, 2013).
Ahead of providing power to the tunnel boring machine:
Overhead 26kV power lines must be upgraded for powering the tunnel boring machine. Work will be done along NE 67th from 8th Avenue NE to Roosevelt Station site. Estimated start (June, 2013.) to completion date (February, 2014).
Excavation and installation of new ductbank by Sound Transit along Weedin Place to provide power to tunnel boring machine. Estimated start (February, 2014) to completion date (April, 2014).
In order for crews to work safely planned power outages will be necessary. We will work to minimize their affects. Customers will be provided with advance notification.
There will be some traffic lane closures on NE 65th, 66th, 67th streets and on Roosevelt Way and 12th Avenue NE. Crews will follow traffic control plans established by Seattle Department of Transportation and work to ensure access is maintained for businesses and residents.
