Interstate-11 Project Status
Interstate-11 Phase I solicited bids on October 29, 2014, and Fisher Sand and Gravel won the project with a $83 million bid alternative that uses concrete pavement instead of asphalt. Federally funded studies show that concrete pavement costs 13 to 28 percent less in the long run than asphalt by reduces rutting, potholes, and maintenance expenses. The project broke ground in May 2015, with anticipated completion by January 2018. Traffic impacts will be confined to the last three months of the project.
Phase 1 of Interstate 11 consists of a continuous four-lane, controlled-access, divided freeway and highway passing south of the developed area of Boulder City. The alignment begins at the Foothills Drive and crosses under the existing railroad, continuing just south to Silverline Road. The project length is about 2.5 miles.
