Heavy congestion is forecast on Interstate 15 between Southern Nevada and Southern California as travelers return from Las Vegas on Labor Day, with peak delays expected midday near the state line. Gas prices remain elevated for the holiday weekend.
Travelers heading between Las Vegas and Southern California for Labor Day weekend should prepare for significant traffic delays on Interstate 15, especially on Monday as visitors return home. The Regional Transportation Commission (RTC) warns that the heaviest congestion is expected southbound near the Nevada-California border, with the worst backups typically occurring between 10 a.m. and 3 p.m.
Las Vegas remains a top Labor Day destination, ranking eighth nationally according to AAA. With thousands expected to celebrate the end of summer in the city, both visitors and locals are advised to plan their travel times carefully to avoid the busiest periods on I-15.
Peak Travel Times and Traffic Tips
The RTC recommends that those leaving Las Vegas for Southern California on Labor Day either depart early in the morning or later in the evening to avoid the midday rush. Real-time traffic updates, construction alerts, and travel advisories are available at SeeingOrangeNV.com, helping drivers make informed decisions before hitting the road.
Southern Nevadans returning from California should also anticipate increased northbound traffic on I-15 heading back into the Las Vegas Valley on Monday. Allowing extra travel time and checking conditions in advance is strongly encouraged.
Gas Prices and Road Trip Costs
This year’s holiday travel comes with higher fuel costs. As of Friday, the average price for a gallon of regular unleaded in the Las Vegas Valley was $4.80, nearly a dollar higher than the same time in 2025, according to AAA. In Southern California, average prices in San Bernardino, Los Angeles, and Orange County range from $5.60 to $5.70 per gallon, up $1.10 from last year.
Vehicle Preparation and Safety
AAA advises motorists to check tire condition and inflation, test batteries, and ensure all fluids are at proper levels before departing. Packing an emergency kit with water, snacks, a first-aid kit, flashlight, and jumper cables is recommended, especially as late August and early September temperatures between Southern Nevada and California often reach 90 to 100 degrees. Last Labor Day weekend, AAA responded to 4,400 roadside assistance calls in Nevada, mostly for flat tires, dead batteries, and towing.
Airport Park-and-Ride Option
For locals flying out of Harry Reid International Airport, the RTC offers a park-and-ride service at the South Strip Transit Terminal near Sunset Road and Gillespie Street. Residents can park for free for up to seven days and take Route 108 or the new Red Line bus directly to the airport. Parking is first-come, first-served, and travelers planning to leave their vehicle for more than a day should notify RTC security at 702-676-1849.
Discounted Lyft Rides to Prevent Impaired Driving
Nevada’s Zero Fatalities program is partnering with Lyft to offer discounted rides on Labor Day, aiming to reduce impaired driving incidents. Starting at noon on Labor Day through 4 p.m. Tuesday, the first 400 riders using code LBRSAFE26 in the Lyft app will receive $5 off one ride. The program continues to promote safe driving and responsible choices for Nevadans during busy travel periods.
Las Vegas Events and Visitor Impact
