Associate Professor of Urban Planning Michael Manville spoke to the Los Angeles Times about Elon Musk’s underground people-mover for the Las Vegas convention center’s expansion. Musk’s Boring Co. secured a $48.7-million contract after the Las Vegas Convention and Visitors Authority board approved construction of the roughly mile-long transit loop. Manville was surprised to learn that an underground plan was more affordable than a proposed elevated rail because tunneling is often more expensive. Based on the few details released by the Boring Co., Manville said it would be difficult to assess the project. “This is kind of a market test for him. Can he now build something that is more commercially viable than what he’s done with his test tunnel in Hawthorne?” Manville said. “But there’s nothing intrinsically interesting about building a tunnel to move people around. That’s what a subway is, right?”
