It’s cone time in Las Vegas. With one month to go until the second Las Vegas Grand Prix, prep work for the race is in full swing, along with the attending traffic disruptions signaled by what seems like thousands of cones and barrels on the streets near the race path. Construction, lane restrictions and tree removals at center Strip are all in progress. But the main indicator is the start of work to build the temporary bridge on Flamingo Road. The bridge will remain in place until early December, when the teardown of the seating, track barriers, course lighting and other elements takes place.
