Remember: I-15 ramps start shutting down as of 5 p.m., and the Strip is traffic free for pedestrians as of 6 p.m. to the expected record 340,000 tourists. For the first time, our monorail will remain open for 44 consecutive hours with a $1 ticket for locals wanting to shuttle between MGM Grand on the south end to SLS Las Vegas on the north end without Strip chaos.
