A deadly collision at the Interstate 11 interchange shut down Boulder Highway in the southeast Las Vegas Valley on Tuesday afternoon, and authorities said a motorcyclist was killed. The closure snarled east-side commutes, with traffic backing up in every direction.
Crash details
The crash was reported at 1:53 p.m. Tuesday at Boulder Highway at the Interstate 11 interchange. An adult male motorcyclist was pronounced dead at the scene, while the driver of a passenger vehicle was taken to a nearby hospital with injuries described as non-life-threatening, according to the Las Vegas Review-Journal. The interchange was shut in both directions as investigators documented the wreckage and collected evidence.
Official alerts and closures
Nevada State Police issued a traffic alert saying State Route 582 (Boulder Highway) was closed in both directions at the I-11 interchange and urged motorists to "Please use alternate routes and avoid area," a notice captured in local coverage. As FOX5 Las Vegas reported, traffic cameras and live feeds showed law enforcement vehicles blocking access ramps while crews cleared the scene, creating backups on nearby surface streets.
Boulder Highway context

Route guides and recent local reporting highlight both the highway’s central role in valley travel and efforts such as a new safety fence meant to reduce pedestrian deaths. Additional background on the route is available from AARoads.
Investigation
Officials have not released the identities of those involved and say the collision remains under investigation, according to initial traffic alerts. Drivers in the east valley were advised to expect delays and use alternate routes while crews worked to reopen the interchange.
