If you've walked or driven past the south portal site for the downtown Bellevue tunnel recently, you've likely noticed some significant changes. Sound Transit's construction crews have continued to clear and grade the site in preparation for tunnel excavation which is anticipated to begin this fall. In advance of the tunnel excavation, a 20-foot temporary sound wall will be installed around the site. 

Crews are now performing utility relocation work to prepare for the installation of the sound wall. A continuation of the intermittent/as needed sidewalk and lane closures will be necessary to complete the utility and sound wall installation work.

Construction of the temporary sound wall is expected to be complete by fall 2016.
