The deadliest highways and corridors in the Las Vegas valley

Nevada recorded 381 traffic deaths in 2025, down nine percent from the 420 killed in 2024, which had been the worst year on record in the state.¹ Clark County still accounted for 239 of those deaths, close to two out of every three fatal crashes statewide.¹ Even with the improvement, Nevada ranks sixth in the country for traffic deaths per mile driven, at 1.49 per 100 million vehicle miles traveled in 2024 against a national average of 1.2, and the state's fatality count is up 45 percent over the past decade.² Fatal and serious crashes cost Nevada an estimated $18.1 billion in 2024 alone, according to the transportation research nonprofit TRIP.²

Those deaths cluster on a short list of roads. One highway in particular has such a lopsided death toll that it reshaped a $185 million infrastructure project, and a handful of intersections show up on police crash lists year after year.

Boulder Highway carries the worst of it

Boulder Highway has more fatalities on it than any other road in Nevada.³ Eleven pedestrians died on the six-lane stretch between Las Vegas and Henderson in 2015 alone, and a 2020 study by the Regional Transportation Commission of Southern Nevada found the highway accounted for roughly ten percent of every pedestrian death statewide, on a single road.⁴ Erin Breen, who directs the Road Equity Alliance at UNLV's Transportation Research Center, points to the highway's 200-foot right-of-way as the underlying problem: wide lanes and long, uninterrupted blocks let drivers build speed and leave almost no reaction time when a pedestrian steps into the road.⁵

The one fix that's demonstrably worked so far is blunt: a fence. LVMPD put up 1,500 feet of metal fencing between Nellis Boulevard and Flamingo Road in October 2024 to funnel pedestrians into marked crosswalks instead of crossing live traffic. Traffic Bureau Captain Jeff Clark says that stretch averaged five pedestrian deaths a year before the fence went in. It's had zero since.⁶ Clark County is now extending the fencing four miles, from Tropicana to Sahara.⁶

A larger rebuild is underway a few miles south in Henderson. The "Reimagine Boulder Highway" project, a partnership between Henderson, the Regional Transportation Commission and the city of Las Vegas, will narrow the 7.5-mile stretch from Wagon Wheel Drive to Tulip Falls Drive from six lanes to four, add a center bus lane, raised bike lanes and new lighting.⁴ Henderson's city council approved the project at $173 million in 2024; the budget has since grown to $185 million, with completion not expected until August 2027.⁷ City officials say the highway accounts for roughly a quarter of Henderson's own traffic fatalities.⁴ Four hundred new streetlights are already lit along the corridor.³

The intersections that keep showing up

Metro's traffic bureau publishes running lists of the valley's highest-crash intersections by area command, and some names repeat across separate reports months apart. A report covering the first months of 2025 put Rainbow Boulevard and Flamingo Road at 26 crashes, Eastern Avenue and Sahara Avenue at 24, and Charleston Boulevard and Lamb Boulevard at 23, part of more than 6,000 collision responses departmentwide that year and 63 traffic deaths to that point.⁸ A separate list covering January 2026 flagged Las Vegas Boulevard and Tropicana Avenue, Eastern Avenue and Stewart Avenue, Charleston Boulevard and Valley View Boulevard, and Lamb and Lake Mead boulevards, with Rainbow and Flamingo still among the busiest.⁹

Volume isn't the only thing that makes an intersection dangerous. Lake Mead Boulevard and Lamont Street sits on a six-lane, 45 mph stretch near three schools. Metro logged 27 crashes there between January 2020 and February 2026, three of them fatal and two involving pedestrians, including a 17-year-old struck in a marked crosswalk on February 7, 2026.¹⁰ NDOT's own pedestrian and bicycle study of that intersection counted a peak hour of 123 people crossing on foot or by bike, exactly the kind of exposure that turns a wide arterial into a hazard for anyone not in a car.¹⁰

A street design problem as much as a driver problem

NDOT safety official Lacey Tisler describes what happens on the valley's grid streets as systemic speeding: drivers going five, ten, fifteen miles an hour over the limit as routine behavior, something she ties partly to how the roads are built and partly to what she calls cultural impatience.¹¹ Breen uses a sharper term for roads like Boulder Highway, Charleston and Rainbow: stroads, wide thoroughfares built like highways but lined with driveways, parking lots and pedestrians, a mix that punishes any mistake.¹¹ She notes pedestrians here die mid-block more often than at intersections, because the blocks are so long that jaywalking becomes the practical way to cross rather than the reckless one.⁵

The toll is climbing fastest for people on foot. Nevada's pedestrian death count rose from 69 in 2019 to 109 in 2023, and 2024 was worse.⁵ Clark County School District logged 142 children struck by vehicles in just the first three months of the 2025-2026 school year, more than the 120 struck during the entire previous year.¹²

What's being done, and what isn't

The city of Las Vegas paid the engineering firm Atkins Realis $800,000 for a Vision Zero safety study that began in December 2024, but the tangible results so far are thin: a bike and pedestrian bridge over Summerlin Parkway and an in-progress protected lane on Stewart Avenue downtown. Meanwhile the city's national bike-friendliness ranking slipped from the 39th percentile in 2024 to the 29th in 2025.¹³ Nine pedestrians were killed valley-wide in the first seven weeks of 2026 alone.¹³ Other projects are further along: the RTC has redesigned Maryland Parkway around a planned transit line, and NDOT has added a new pedestrian crossing on Spring Mountain Road through Chinatown.¹²

If you're hurt on one of these roads

Crashes on corridors like these tend to produce injuries that don't resolve quickly, broken bones, head trauma, months of physical therapy. Nevada follows a modified comparative negligence rule under NRS 41.141: an injured person can still recover damages as long as they're not more than 50 percent at fault, though any award gets reduced by their share of the blame.¹⁴ That makes early documentation, of the intersection, the signal timing, the crosswalk markings, genuinely matter to a claim. If you need help finding an attorney who handles Nevada crash cases, the legal directory is a place to start.
