Both directions of State Route 163 near Laughlin are shut down at mile marker 7 following a fatal crash Sunday, cutting off the main highway link between the resort town and U.S. Route 95. Nevada State Police say the closure has no set end time, and drivers are being told to stay away from the area entirely.
Deadly Crash Forces Full Shutdown
In a post on X, Nevada State Police confirmed that eastbound and westbound travel lanes on SR 163, also known as the Laughlin Highway, are both closed at mile marker 7 due to a fatal crash. The agency said the highway will remain closed for an unknown amount of time and urged drivers to use alternate routes and avoid the area. Anyone with an emergency in the vicinity was told to call 911.
Mile marker 7 sits in rural desert terrain roughly midway along the highway's 19.25-mile route through unincorporated Clark County, west of Christmas Tree Pass Road, according to the Las Vegas Sun. The corridor, officially the Colorado River Highway, connects U.S. 95 at Palm Gardens to Laughlin and Bullhead City, Arizona, and serves as the primary vehicular route into the riverfront casino district, per Wikipedia. With both lanes shut at once, the closure effectively severs Laughlin's main highway access to US 95, leaving drivers to seek detours through routes like Needles Highway or roads on the Arizona side of the river.
A Highway With a Troubled Recent History
This is not the first time SR 163 has seen a deadly, high-profile crash in this same stretch. In March 2024, a semi-truck driver traveling on the wrong side of the road caused a crash that killed three motorcyclists from St. George, Utah; the truck driver was later sentenced to four to 10 years in prison for reckless driving resulting in death, the Las Vegas Review-Journal reported. Investigators in that case noted extreme driving fatigue and lane drifting, though initial DUI charges were dropped after toxicology showed no substance impairment.
Just over a year later, in April 2025, a fatal rollover crash near mile marker 8 — about one mile from Sunday's crash site — killed a 31-year-old Las Vegas woman and injured several of the 10 occupants riding in an overturned SUV. The driver in that crash was charged with felony DUI and reckless driving after multiple unrestrained passengers were ejected into the median, according to the same Review-Journal report.
Why This Corridor Stays Dangerous
SR 163 is an undivided, high-speed two-lane road that traverses rural desert mountain terrain with sparse emergency infrastructure between US 95 and Laughlin. The highway once carried a heavier burden than its design intended: after September 11, 2001, security restrictions banned commercial trucks from crossing Hoover Dam, forcing freight traffic between Las Vegas and Phoenix onto SR 163 and through Bullhead City for nine years, until the Mike O'Callaghan–Pat Tillman Memorial Bridge opened in October 2010, per Wikipedia.
Statewide, Clark County carries an outsized share of Nevada's traffic deaths. The county accounted for 297 of Nevada's 419 total traffic fatalities in 2024 — roughly 71% of all deaths statewide that year — according to Nevada Office of Traffic Safety data reported by Morris Injury Law. Nevada Department of Transportation and Zero Fatalities data further shows that between 2015 and 2019, nearly two-thirds of the state's fatal lane-departure crashes happened in Clark County, with vehicles drifting across centerlines or onto dirt shoulders on two-lane rural corridors like this one.
A June 2026 study from UNLV's Nevada Traffic Safety Research Center found that 38 fatal wrong-way crashes caused 57 deaths across Nevada between 2017 and 2024, with more than half of those crashes — 23 — happening in Clark County, News 3 Las Vegas reported. Researchers noted that high alcohol impairment is present in nearly 70% of fatal wrong-way crashes nationally.
Still, the broader trend in Clark County has been improving. Preliminary 2026 data showed a nearly 25% drop in traffic deaths compared to the same period in 2025, marking 14 consecutive months of year-over-year fatality reductions, according to News 3 Las Vegas. Traffic safety officials attributed the decline to decreases in speeding and impaired driving.
No further details on Sunday's crash, including the number of people involved or the cause, have been released. Nevada State Police have not indicated when SR 163 will reopen, and drivers headed toward Laughlin should expect delays and detours until the investigation concludes.
