Construction on the project will occur in four phases, with the first work phase (1a) occurring on the north side of Sprague Avenue westward between Sullivan and the 14900 block of Sprague. That phase starts Monday and is expected to be complete in early June, when the project moves into its second phase (1b) on the south side of that same section of Sprague.
Sprague Avenue west of the 14900 block to Evergreen Road will be the focus of the project's third (2a) and fourth (2b) phases. Work on the third phase is expected to begin along the north side of the section in early July, with the fourth and final phase starting in late July and completing in mid-August.
During each phase, the section of Sprague Avenue under construction will be reduced to one lane each direction with a center turn lane. The work also involves closures to northbound and/or southbound intersections in the area under construction.
You can expect traffic congestion and delays in the project area and probably want to use alternate routes.
