SACRAMENTO (CBS13) β€” Investigators are looking into what caused a crash involving a car and a street sweeper in Sacramento early Wednesday morning.

It happened around 2:30 a.m. on the ramp connecting eastbound Highway 5 to northbound Interstate 5.

The ramp was closed for construction, so it’s unclear how the car got onto the roadway.

Authorities have not said if anyone was injured.
