SAN DIEGO (CNS) - One person was killed when two drivers crashed their vehicles and blocked the transition road from westbound Route 56 to southbound Interstate 15 near Del Mar Sunday.

California Highway Patrol officers said the wreck occurred at 7:31 a.m. on the elevated ramp that links the Ted Williams Freeway to Interstate 15 north of the Interstate 805 interchange.

San Diego Police traffic units helped control traffic until both cars were towed away, and the ramp reopened after about two hours.

No names or crash details were immediately released.
