Semi-truck crash closes several lanes on westbound 91 Freeway in Yorba Linda

All lanes of the westbound 91 Freeway in Yorba Linda have reopened after a hours-long closure after a semi-truck crash.

The California Highway Patrol issued a Sig Alert on the 91 freeway at the 241 Freeway, which was cleared around 8:11 a.m. The closure caused a backup from Main Street in Corona.

KCAL News had also issued a Next Traffic Alert to warn drivers about the impact on their morning commute.

It is unclear what led up to the crash.
