Police spokesman Sgt. Paul Shavack says 49-year-old Robert Smith of Wilmington was struck and killed about 4 a.m. Saturday near Farrand Drive. Investigators believe Smith was trying to cross the westbound lanes of the highway when he was struck.
Shavack says the state trooper was a 43-year-old male. But the name of the trooper was not immediately released. The trooper was not injured.
Police say alcohol appears to be a factor in the crash on the part of the pedestrian. An investigation continues.
The incident shut down the road for more than three hours, but it has since reopened.
