A Livermore woman was fatally struck by an SUV after walking into the travel lanes of Interstate 580 in Livermore early Thursday morning, according to the California Highway Patrol.
The decedent, who was 52 years old according to the CHP, had not yet been publicly identified by the Alameda County Coroner's Bureau as of Friday afternoon.
According to CHP Officer Tyler Hahn, the woman was walking on the right shoulder of westbound I-580 near the Las Colinas Road overpass -- between First Street and North Livermore Avenue -- at approximately 4 a.m. Thursday when for an unknown reason moved into the driving lanes where she was struck by a Ford Explorer.
The collision with the SUV caused fatal injuries for the pedestrian, who was pronounced dead at the scene, according to Hahn.
Officers do not think alcohol was a factor in the crash for the Explorer driver, a 56-year-old man from Lathrop whose name was not released, according to Hahn.
The investigation into the collision is ongoing. Hahn said any potential witnesses should call the CHP-Dublin office 925-828-0466.
Bay City News Service previously reported the CHP began receiving reports of a person walking in the center divider, on the roadway and in the right shoulder of the freeway at 3:41 a.m. before the woman was hit.
This marked the second freeway pedestrian fatality of the week in the Tri-Valley. Another woman was struck and killed on Interstate 680 in San Ramon around 1 a.m. last Monday.
