The corridors, ranked by serious crashes

A Safer Streets Priority Network covers the RTC of Southern Nevada's service area. It maps the streets where crashes that killed or seriously injured someone (KSI crashes) cluster. It is an ArcGIS item dated September 9, 2025. It was posted the next day in the AtkinsRéalis ArcGIS organization, not an RTC account (ArcGIS item).

The table adds up every segment of each street name in the regional network and ranks them. The last column is our arithmetic, KSI crashes divided by miles, so a long street and a short one can be compared.

Streets with 32 or more KSI crashes, 21 in all. The data lists a street by name and direction, so some roads are split: N Eastern Ave (16 KSI crashes in 2.05 miles) and N Boulder Hwy in Henderson (7 in 2.93 miles) are separate rows below the cutoff. Miles are the length of each street name inside the network, summed across its segments. The per-mile column is InjuryCatch arithmetic on those figures.

Two readings stand out. By total, South Las Vegas Boulevard leads, but its 75 KSI crashes are spread over about 30 miles of the network. By density, East Flamingo Road is highest: 51 KSI crashes in 6.06 miles, about 8.4 per mile.

The RTC layer does not define its KSI field. The City of Las Vegas's own network counts KSI crashes, which are Type K (fatal) or Type A (serious injury) crashes in NDOT data (City of Las Vegas Vision Zero plan). This page reads the RTC figure the same way. The layer also gives no count of deaths, so this page does not report deaths by street.

Inside the City of Las Vegas

The same data has a layer for the City of Las Vegas alone. Its top streets by KSI crashes (City of Las Vegas layer):

• W Charleston Blvd: 43
• W Sahara Ave: 31
• E Bonanza Rd: 27
• W Lake Mead Blvd: 26
• N Decatur Blvd: 23
• S Decatur Blvd: 23
• W Washington Ave: 19

The City's own Vision Zero plan used NDOT crash data from 2015 to 2019. It found that 77% of the city's serious injury and fatal crashes happened on almost 11% of its streets, about 148 miles. The city averaged one traffic death and three and a half serious injuries every week (City of Las Vegas Vision Zero plan, 2022).

The 12 intersections LVMPD targeted in 2025

In September 2025, FOX5 reported that LVMPD had moved officers onto special enforcement at 12 intersections in its area. Its analysts had identified them as the deadliest over the last three years. The work started in August 2025 and was planned to run for the year. Officers were looking for speed, failure to yield and impairment (as reported by FOX5, September 3, 2025).

The list, in the order FOX5 published it:

1. Charleston Blvd and Decatur Blvd
2. Flamingo Rd and Rainbow Blvd
3. Charleston Blvd and Hualapai Way
4. Blue Diamond Rd and Arville St
5. Tropicana Ave and Decatur Blvd
6. Flamingo Rd and Arville St
7. Boulder Hwy, Sahara Ave to Karen Ave
8. Flamingo Rd and Pecos Rd
9. Flamingo Rd and Maryland Pkwy
10. Las Vegas Blvd and Cheyenne Ave
11. Washington Ave and Nellis Blvd
12. Las Vegas Blvd and Cashman Center

This is a news report of a police list, not published crash data, and it gives no counts for each intersection. Flamingo Road appears four times. In the RTC-area data above, East Flamingo Road also has the most KSI crashes per mile of any street with 20 or more.

Ten intersections the city studied

The City of Las Vegas studied ten intersections under its Citywide Intersection Crash Mitigation Program. They were chosen for a safety program, not published as a ranked list of the worst. Crash totals are for 2014 to 2018, from NDOT data (City of Las Vegas Vision Zero plan, 2022).

Across the ten, 513 crashes were angle crashes and 445 were rear-end crashes. At Durango and Charleston, left turns and U-turns made up 54.9% of the first vehicle's actions. After the city rebuilt that intersection, crashes fell from 39 a year to 6 (City of Las Vegas Vision Zero plan, 2022).

Boulder Highway

The RTC-area data splits Boulder Highway in two. The stretch it names Boulder Hwy has 38 KSI crashes in 6.37 miles. N Boulder Hwy in Henderson adds 7 in 2.93 miles (RTC-area data). The stretch from Sahara Avenue to Karen Avenue is on LVMPD's 2025 enforcement list above.

FOX5 reported in July 2026 that a 2020 RTC study found about 10% of Nevada's pedestrian deaths happened on Boulder Highway. It also reported that Henderson's Reimagine Boulder Highway project covers 7.5 miles inside Henderson city limits. The project is now estimated at $185 million and is not scheduled to finish until August 2027 (as reported by FOX5).

The statewide picture

• Nevada recorded 380 traffic deaths in 2025 and 420 in 2024. Clark County had 235 of the 2025 deaths, 61.8% (Office of Traffic Safety, preliminary 2024 and 2025 data). FARS counts 417 for 2024 (Crash Facts).
• From 2020 to 2024, Clark County had 1,154 of Nevada's 1,798 fatal crashes, 64% (Nevada Traffic Safety Crash Facts).
• Impaired driving was 45% of Nevada traffic deaths from 2020 to 2024, 888 deaths. Of fatal impaired crashes, 58% happened between 6 PM and 6 AM. Lane departure was 40%, intersections 33% and speeding 30%. The categories overlap (Crash Facts).
• From 2019 to 2023, almost 75% of Nevada's deaths and serious injuries were on urban roads. Minor arterials, a class of through street below the main arterials and freeways, had 36.5% of fatal crashes (Strategic Highway Safety Plan).
• Census tracts below Nevada's 2024 median household income of $81,134 had a 143% higher pedestrian fatality rate than tracts at or above it (Crash Facts).

Pedestrians were 34.5% of Clark County traffic deaths in 2025 (Office of Traffic Safety, preliminary). Nevada law requires drivers to use due care to avoid hitting a pedestrian (NRS 484B.280).
