Two weekends of SR 18 lane closures over Tiger Mountain planned; safety improvements coming to dark roadway

The Washington State Department of Transportation says work to improve safety on SR 18 on Tiger Mountain starts Friday night, November 4, 2016 with the first of four overnight directional closures on the highway

Contractor crews working for WSDIT will close one direction of the highway Friday and Saturday nights, Novemeber 4-5, and Nov. 11-12, alternating the closures each evening. The nightly closures will be between I-90 and Issaquah-Hobart Road.

The crews will install glare screen blades on top of the concrete barrier separating eastbound and westbound traffic. They will also install additional reflective safety markings on the side of the concrete barrier.

WSDOT said installing glare screens will help block the glare of vehicles traveling in the opposite direction on this stretch of SR 18 that is very dark – a section that also does not have street lights. The new reflective markers are expected to help guide drivers over Tiger Mountain.

Closure details

The SR 18 directional overnight closures will be nightly from 8PM to 8AM:

  • Friday, Nov. 4, to the morning of Saturday, Nov. 5 – Westbound from Issaquah-Hobart Road to I-90.
  • Saturday, Nov. 5, to the morning of Sunday, Nov. 6 – Eastbound from I-90 to Issaquah-Hobart Road.
  • Friday, Nov. 11, to the morning of Saturday, Nov. 12 – Westbound from Issaquah-Hobart Road to I-90.
  • Saturday, Nov. 12, to the morning of Sunday, Nov. 13 – Eastbound from I-90 to Issaquah-Hobart Road.
