More road construction is coming to Las Vegas as officials broke ground Tuesday on the U.S. 95 Northwest Corridor Improvement Project. The project will widen U.S. 95 from Washington Avenue to Ann Road by adding a high-occupancy vehicle lane. It also includes major renovations to interchanges along the corridor and will add landscaping and sound walls to parts of the freeway. While the work means 2 1/2 years of construction for motorists, officials promise the end result will be worth the hassle and point out the economic benefits of construction.
