Construction work on Argonne Avenue starts soon and will continue into July. The project will create a smoother and safer driving surface, upgrade sidewalks and curbs to meet Americans with Disabilities Act requirements, and upgrade stormwater drainage. The work will occur in four segments: Sprague from University to Herald, Argonne from Broadway to Sprague, Sprague from I-90 to Theirman, and Sprague from Havana to I-90. The Spokane Valley Herald has all the details.
