Plan for three weeks of overnight closures of SR 99 in Seattle

Monday, April 4, 2016


Drivers should expect full weeknight closures in one direction of State Route 99 / Aurora Avenue North during the next three weeks just north of downtown Seattle.

During the closures, crews working for Atkinson Construction will close one direction of the highway to install street lights, traffic sensors and sign bridges. The closures are part of ongoing work to build the roadway and ramp connections between Aurora Avenue North and the north portal of the SR 99 tunnel.

Closure details
  • Monday, April 4, to the morning of Friday, April 8: Crews will close all lanes of northbound SR 99/Aurora Avenue each night from 10 p.m. to 5 a.m. from the south end of the Battery Street Tunnel to Valley Street.
  • Monday, April 11, to the morning of Saturday, April 16: Crews will close all lanes of southbound SR 99/Aurora Avenue North each night from 10 p.m. to 5 a.m. from Valley to Thomas streets.
  • Monday, April 18, to the morning of Tuesday, April 19: Crews will close all lanes of southbound SR 99/Aurora Avenue North from the Fremont Way North on-ramp to the south end of the Battery Street Tunnel from 10 p.m. to 5 a.m.
    • Crews will also close the left lane on northbound SR 99 between Mercer Street and the south end of the Aurora Bridge from 7 p.m. to 5 a.m.
  • Tuesday, April 19, to the morning of Friday, April 22: Crews will close all lanes of southbound SR 99/Aurora Avenue North just south of the Dexter Avenue North exit to the south end of the Battery Street Tunnel from 10 p.m. to 5 a.m.
    • Crews will also close the left lane on northbound SR 99/Aurora Avenue North between Mercer Street and the south end of the Aurora Bridge each night from 7 p.m. to 5 a.m.

I'm wondering what the value of building ramps to a portal to a tunnel that will never be completed is.
