Pine Street Stub Tunnel

Highlights

Sound Transit is building a short "stub" tunnel under Pine Street between Seventh and Boren avenues  to allow light rail trains running in the downtown tunnel to stop and reverse direction.

• Stub tunnel construction began in Fall 2004, and will take up to two and-a-half years to complete.
• The first stage of construction created a construction work area on the north side and two west-bound travel lanes on the south side of Pine Street.
• The tunnel is being dug out at the surface and the hole capped by a temporary lid or deck to allow traffic to pass over while construction continues below. The temporary decking is scheduled to be complete in the summer of 2005.
• The contractor then begn digging and building the tunnel, working 40 to 80 feet below street level.

• In September 2005 when the DSTT closed to be retrofitted, the existing tunnel at Convention Place Station was demolished in order to be adjoined to the new stub tunnel.
