ROCKAWAY TOWNSHIP —

A man was killed walking across the eastbound lanes of Interstate 80 in Morris County after he had successfully crossed the westbound lanes, police said.

It was unclear why the man, who was not identified by police, was crossing the six-lane highway, police said.

Two of the three eastbound lanes just east of exit 34 were closed about 10:30 p.m. for the investigation, a State Police spokesman said tonight. Exit 34, in Wharton, connects with Route 15.

Then, an hour later, all eastbound interstate lanes were briefly shut down just west in Jefferson Township following another accident.

Police had been called about 9 p.m. , when the man appeared to have been struck by two separate vehicles in the left eastbound lanes just after crossing the median, the spokesman said.

The drivers of the vehicles, a Buick and a Toyota RAV-4, remained on scene, the spokesman said.

Then, just west in Jefferson Township about 11:30 p.m. there was another serious accident that shut down all three eastbound lanes of traffic, according to the state transportation website. Once a medevac helicopter landed to take away a victim, the left lane opened up, the website, nj511.org, reported.
