Northbound traffic on I-15 through downtown Las Vegas ground to a halt Saturday after a crash that Nevada State Police described as fatal shut down all travel lanes at Washington Avenue and blocked a key ramp connection from I-11.
Motorists on I-15 northbound were being forced off at D Street, with the on-ramp from I-11 to I-15 northbound also closed, creating heavy delays in the downtown corridor.
According to Nevada State Police, "IR15 northbound at Washington has all travel lanes closed." The post also reported that the I-11 to I-15 northbound ramp is shut down and that northbound traffic is being diverted to the D Street off-ramp.
What Drivers Need To Know
Nevada State Police urged drivers to steer clear of the area and use alternate routes while emergency crews and investigators work the scene. Anyone approaching the closure should plan for delays and expect spillover onto nearby surface streets as detoured traffic tries to snake around the shutdown.
Officials also reminded motorists to give crews plenty of space so they can safely manage the investigation and clear the freeway.
How This Fits Into Nevada's Crash Trends
State data compiled by the Nevada Legislative Counsel’s research division show that traffic deaths have risen in recent years, with pedestrian fatalities making up about 24% of all traffic deaths statewide from 2015 through 2024, according to Nevada Legislative Research. That broader pattern is one reason investigators often keep highways closed for extended periods after fatal crashes so they can thoroughly document the scene and collect evidence.
Other deadly crashes on I-15 have led to multi-hour closures in past years, with lanes reopening only after state police and the Regional Transportation Commission coordinated to fully clear the area, as KTNV reported. Those shutdowns typically push vehicles onto nearby streets and create long backups for downtown commuters.
Where To Get Updates
Nevada State Police said it will continue to post updates on its social feed. Drivers can also monitor the Nevada Highway Patrol real-time incident page for closure and detour information. Visit the Nevada Highway Patrol site for the latest advisories.
