One person was injured as his car drove into a construction site in Otay Mesa, traveled over a ditch and flipped onto its roof.
The collision happened just after 6 a.m. at Drucker Lane, near Siempre Viva Road, within walking distance from the U.S.-Mexico border.
A man was pulled from the wreckage of the car. He told one witness before emergency personnel arrived that he could feel his toes but was having trouble breathing because of the seatbelt.
Chula Vista firefighters and San Diego Fire-Rescue crews responded. They transported the man to a nearby hospital by air ambulance.
Several power lines were knocked down at the construction site.
One worker said he was concerned how the collision was going to delay the project.
The construction site is located just north of the U.S.-Mexico border and southwest of where Interstate 905 connects with State Route 125.
