ELK GROVE (CBS13) – A pair of crashes involving several vehicles has traffic on Interstate 5 just south of Elk Grove moving very slow Tuesday morning.

The first crash happened around 5:30 a.m. near the Hood Franklin Road off-ramp from the southbound side of I-5. In this crash, there were two vehicles involved.

About a half-hour later, several other vehicles were involved in another crash in the same area.

Exactly what led to both crashes, and if the crashes are related, is unclear at this point.
