SEI Project: 18th Street Closure

18th Street, 11th Avenue to I-10 March 31, 2017

On Monday, April 3, 2017 the contractor will begin work to install three large-diameter pipes and two manhole structures on 18th Street just west of the Tucson Water Plant 1 facility. Because of the large excavation required to complete the work, 18th Street will be closed to through traffic from 11th Avenue to the northbound I-10 frontage road (see attached map). This closure will remain in place through the middle of May 2017.
