A motorcyclist died after a crash within a construction zone on eastbound Interstate 80 in Placer County on Wednesday, causing a significant traffic delay, according to authorities.

The Placer County Sheriff's Office identified the motorcyclist on Thursday as Lonidas Castro, 78.

The California Highway Patrol said the crash happened on eastbound I-80 at the Crystal Springs Road overpass around 3 p.m.

Not many details are known at this time, as an investigation is underway to determine what led up to the crash.

Caltrans said the crash happened within a construction zone and that one of its trucks was involved in the incident. 

The CHP said traffic was being diverted off the highway as the eastbound lanes were blocked. All lanes have since reopened.
