A fatal crash caused major traffic disruptions overnight on I-95 in the Milford area.

State police say the one-vehicle crash happened Sunday night and resulted in a fatality.

Earlier, the Connecticut Department of Transportation said I-95 north was shut down between exits 40 and 41 in Milford.

Officials also closed I-95 south in Orange between exits 41 and 40, along with the southbound on-ramp at Exit 41.

All lanes have since reopened, but authorities have confirmed the crash was fatal.

Officials have not released information about the victim or what may have caused the crash.

The investigation remains ongoing.
