"Police activity" has Interstate 68 closed in both directions near the Maryland border, in Preston County, according to 911 officials.

State Police Captain Shallon Oglesby said that the shutdown came after a routine traffic stop at about 10:30 a.m. Wednesday for speeding along the eastbound lanes.

The trooper determined that the stop would require an "in-depth investigation" leading to the shutdown, Oglesby said.

The closure in the eastbound lanes is at mile marker 23, which is the Bruceton Mills exit, according to WV 511. The westbound lanes are closed in Maryland, with detours set up at exits 14(Uniontown-U.S. Route 40 West/Oakland-U.S. Route 219 South) and exit 4(Friendsville), according to Maryland State Police. All trucks must exit at exit 14, Maryland state troopers said.
