TWIN FALLS, Idaho (KLIX) Constructions crews will install new water lines in south Twin Falls that will impact local traffic. On Tuesday, according to the city of Twin Falls, contractors will be working at Southwood Avenue and Ponderosa Street which will require a detour for people living east of the project.
