Elon Musk's tunnel construction company, The Boring Company, has been given the green light to build a 10.3-mile tunnel under Las Vegas. The new tunnel will be used as an innovative transportation system for pedestrians. Passengers will be transported in Tesla electric vehicles at speeds of up to 155 miles per hour. The project aims to alleviate traffic congestion and provide a faster, more efficient transportation option for residents and tourists in Las Vegas. The tunnel is expected to be completed by January 2021.
