The truck off to the shoulder just south of Interstate 80 in the main roadway but traffic backs up to at least Route 46. I-80 also has delays eastbound in Denville approaching I-287.

The trailer portion split and rolls of paper are on the roadway along with a fuel spill that will need to be cleaned up.

New Jersey 101.5's Bob Williams suggests taking Route 202 or 511 to get around the expected delays.
