A full nine-day closure of Koval Lane between Harmon Avenue and Flamingo Road begins late Friday night, Nov. 13, 2026, ahead of the fourth Las Vegas Grand Prix. Drivers and transit riders in the resort corridor should expect detours and plan extra travel time before the race takes place next Thursday, Friday, and Saturday nights.
Traffic cones are already set up along four major roadways in and around the Strip and will soon be replaced with barricades. Clark County Public Works approved the road closures as part of an annual transportation management plan developed with race organizers, Formula 1 representatives said.
Public transit riders using Regional Transportation Commission buses may need to walk up to a mile to reach detoured stops. An RTC representative noted that Route 119 travels to Paradise Road, which remains open now and will stay open throughout race week. The agency advised riders to check route updates on the RTC and Las Vegas Grand Prix websites ahead of time, adding that extra outreach staff will be stationed on the streets during race week to help passengers navigate the changes.
Race organizers are also running an employee mobility program designed to help resort corridor hospitality workers get to and from their shifts during the event. A Grand Prix community affairs representative said planners are applying lessons from previous years to speed up the construction and removal of grandstands and hospitality suites, offer single-night tickets, and improve communication with local workers.
Near the circuit, a family-owned business operator at Las Vegas Souvenirs and Gifts said setup and teardown still strain storefront operations, though the disruption window has shortened each year. According to the business operator, disruptions lasted seven to eight months in the first year and five to six months in the second year, compared with about three months in the third year and this year.
Local officials said the event carries the same special event assessment rating from Las Vegas police as New Year's Eve, and the event promoter funds most of the extra law enforcement manpower costs rather than taxpayers. Over its first three years combined, the Las Vegas Grand Prix generated $3.2 billion in economic impact, $43 million in tax revenue, and hundreds of jobs, with attendees spending an average of about $2,400 outside of race tickets.
