As investigators look into what caused the crash that killed two active-duty U.S. Navy sailors on the ramp leading from Interstate 5 to State Route 54, the incident has renewed safety concerns about the ramp.

10News learned Caltrans will be reviewing the collision report on Tuesday's fatal plunge.

Authorities said it is estimated the driver of the 1998 Corvette was going nearly 100 mph when it crashed over the rail and fell 100 feet below, landing upside down and killing the driver and passenger who were both active-duty sailors.

The San Diego County Medical Examiner's Office identified the passenger as 25-year-old Seth Hartin. The driver was identified as 20-year-old Brian Davis.

Authorities believe the car was traveling at an excessive speed, but the ramp is known for being sharply curved and steep. Driver Jackie Hermiz called the I-5 ramp to SR-54 "scary" and doesn't allow her teenage son to drive it.

"I have my son, he's 17, he just got his license and I don't let him go nowhere … just to school because he just started," Hermiz told 10News.

In at least the past 5 years, 10News has covered other dramatic and deadly crashes where cars flew off the 100-foot high ramp.

There have been calls for higher barriers, but to date only 50 mph speed limit signs have been posted to warn drivers to slow down.

"These are based on traffic engineering studies and the design. These are the suggested safe speeds to traverse through those locations," said Brian Pennings of the California Highway Patrol.
