Northbound Interstate 81 is closed between exit 283 (Woodstock) in Shenandoah County and exit 302 (Middletown) in Frederick County. The closure is due to a diesel spill from a tanker truck. Cleanup efforts are under way, but there is no estimated time for reopening northbound I-81.
Northbound traffic is detoured at exit 283 and will be directed to follow Route 11 north through Shenandoah and Frederick counties. Northbound traffic rejoins I-81 at exit 302. The northbound on-ramps at exit 291 (Toms Brook), exit 296 (Strasburg) and exit 298 (Strasburg) are closed. Virginia State Police is assisting with traffic control.
