WEST ORANGE, NJ -- Icy conditions have forced the Essex County Sheriff's office to shut down lanes on Pleasant Valley Way in West Orange Sunday evening.

Lanes on the thoroughfare were being closed off after 8 p.m. Sunday. Temperatures which had been in the low 40s earlier in the afternoon were plummeting and forecast to reach single-digits overnight, creating fast freezing of surfaces still damp from more than an inch of rain Saturday night and Sunday morning.
