In addition, Xcel Energy will be working in the same area to replace some of its underground infrastructure. Work will take place between 8 a.m. and 4:30 p.m. Mondays through Fridays. Travelers along the road can expect lane closures and travel delays during working hours. A temporary traffic signal will be used at night and on weekends as the road will be reduced to one lane 24 hours a day, seven days a week. A full road closure may be necessary to perform certain aspects of the work. More information will be posted should the road need to be closed. The project is anticipated to last into later this spring or into the summer.
