WARREN, NJ - After a harrowing afternoon in Somerset and Union Counties, flood waters have receded and both I-78 and Route 22 have cleared. Thunderstorms this afternoon caused significant flash flooding all along the Route 22 and I-78 corridor.

Crews worked through the night however only the shoulder is open on Route 22 East from Westfield Road to New Providence Road. The Scotch Plains section of Route 22 should be avoided if possible.The light is out at the Park Avenue overpass.

Standing water and flooded exits caused miles long backup on Route 78 westbound and  sections of Route 22 flooded, stranding residents for miles in both directions. A partial collapse at the Weldon quarry crushed a number of employee vehicles located at the Weldon Materials' quarry site. Running water crossed the median on Route 22 with the pavement buckling as water poured beneath it. Expect some delays overnight and Thursday morning as repairs take place on Route 22.

Up the road from the quarry, Berkeley Heights Fire Department made three separate water rescues at Twin Falls Road and Valley Road, at Diamond Hill Road and Valley Road and at Glenside Avenue and Valley Road.
