Two Vacherie residents died in a crash Thursday morning when one driver crossed the center line at the crest of a bridge in St. James Parish and struck the other vehicle head-on, State Police said.

Nicole Hebert, 40, was traveling east on La. 20 near the Lafourche Parish line shortly before 11 a.m. Thursday when her Pontiac crossed the center line of the road as it crested the Bayou Chevreuil Bridge and struck a Kia Optima driven by Mitzi Oubre, 45, said Trooper 1st Class Evan Harrell, a State Police Troop C spokesman, in a news release.

Hebert, who was wearing a seat belt, was pronounced dead at the scene, Harrell said. Oubre, who was not wearing a seat belt, also died at the scene, he said.

Impairment is unknown at this time, and toxicology tests are pending for both drivers. The crash remains under investigation, Harrell said.
