Sidewalk Development Program: 13th Ave NW / NW 90th St

Construction Update – October 3, 2013

Construction was expected to begin on September 23rd but is now delayed in order to first resolve a conflict with an existing gas line. We hope to return to the site and start construction by mid-October.

Construction Update – August 22, 2013

SDOT expects to start construction of the new sidewalk on September 23, 2013, with work completed by November 1, 2013.

Construction notices from the contractor with additional information will be distributed 2 – 3 weeks prior to the start of construction. In general, construction will begin with excavation of the area and installation of new drainage facilities.
