Subject:
Street Closures Needed to Accomplish Light Rail Construction
ISSUE:
Over the next 18 months, the construction of Sound Transit's light-rail guideway will be crossing
public streets. In order to ensure pJblic safety, the streets will be closed to traffic, except local
access.
DISCUSSION:
Sound Transit's light-rail route crosses Tukwila's public streets in thirteen (13) different
locations. See Attachment 1 for the first four locations. In addition it crosses SR-599, 1-5, BNSF
tracks, Metro's Bus Ramp onto SR-599, and Boeing AccessIMLK.
Construction is authorized during the hours of 7 :00 am until I 0:00 pm. As an alternative to
completely closing Tukwila's streets, Sound Transit's contractor requested the City investigate
the possibility of a noise variance that would allow construction from 10:00 pm to 7:00 am.
Unfortunately, it appears that several ofth~se aforementioned locations will not be able to satisfy
the criteria set forth in TMC 8.22.180, Variil.llces - Administrator's Authority, for a noise
vanance.
Therefore, to ensure public safety during the construction of selected columns, straddle bents, and
the erection of guideway elements, Public Works cannot allow any traffic (except local access)
within the construction area. The streets within the vicinity ofthe crossings will be closed to
through traffic and detour routes established.
Public Works will be working with Sound Transit to establish detour routes and ensure that the
traveling public has adequate advance notification of the closure. Closure in some instances will
be for several weeks.
This evening's presentation will address the plans for closing Southcenter Blvd. (Attachment 2),
51st Avenue South (Attachment 3), and 52nd Avenue (Attachment 4).
Notification of the pending closure for Southcenter Blvd is in place now and closure is scheduled
to begin June 30th.
