Road construction in the Spokane area is still ramping up for the season, but drivers and business owners are already frustrated by delays and detours. The state will up the ante Monday when it begins rut repair on Interstate 90 through east Spokane, a route that carries 100,000 vehicles a day. The work will be at night, so officials said they don’t expect major slowdowns. All travel lanes will be open from 6 a.m. to 7 p.m.
