A fatal motorcycle crash in downtown Los Angeles forced the closure of a freeway transition ramp for two hours early Wednesday, according to the California Highway Patrol, prompting a SigAlert.

The solo crash on the ramp from the westbound 10 Freeway to the northbound 110 Freeway was reported shortly before 5 a.m. A motorcyclist, whose age and gender were not immediately reported, struck a guardrail and was thrown off the transition road and landed on Venice Boulevard just below, authorities said.

The Los Angeles Fire Department said firefighters were sent to the 700 block of Venice Boulevard. The motorcyclist was pronounced dead at the scene.

The CHP issued a SigAlert for two hours while it investigated the crash.


The transition road was reopened about 7 a.m., the CHP said.
