Police said the body of Reishaun Michael Hopkins of Malden was found at about 6:30 a.m. Thursday near Exit 21. Police said he usually worked the day shift at Honeydew Donuts.
Police said it appears Hopkins was struck while crossing the northbound lanes of the eight-lane highway. His body was thrown into the southbound lanes, where it was struck again. The two sides of the highway are divided by Jersey barriers.
Police closed lanes on both sides of the highway, causing major commuter delays Thursday morning.
No charges were filed. Police did not say why he was trying to cross.
