A 14-year-old boy was struck and killed while trying to cross Interstate 30 in Grand Prairie this afternoon, authorities said.

Nicholas Scroggs of Grand Prairie had left school early with a classmate at the Grand Prairie High School Ninth Grade Center when Nicholas decided to take a shortcut across the freeway about 2:30 p.m., said Sgt. Eric Hansen, a Grand Prairie police spokesman. A Chevy Suburban struck him near the Belt Line Road exit.

His friend, who was not identified, crossed at an underpass and was not injured, Sgt. Hansen said. Both teens were members of the Grand Prairie High swim team.

The SUV driver said he did not see the boy in time to stop, Sgt. Hansen said. He was not issued a citation.

Eastbound lanes of I-30 were shut down for two hours as police investigated the crash.
