The portion of Western Avenue near Charleston Boulevard reopened at about 8:55 a.m. Wednesday after a crash involving a semitrailer.
The crash was reported just after 4 a.m. on the eastbound Charleston off-ramp of northbound Interstate 15, according to Nevada Highway Patrol. Traffic cameras show a trail of dirt and debris leading off I-15 and across the off-ramp.
The semitrailer crashed into a dirt area off the ramp. It has been towed away, the highway patrol said.
The Charleston off-ramp is closed due to road construction.
