After a full track evaluation by NASCAR and International Speedway Corporation (ISC), Martinsville Speedway will add to its existing barrier system in advance of the STP 500 weekend March 27-29.

Tire pack barriers will be installed on the inside wall at the end of the backstretch, prior to the entrance of pit road.

“We are committed to the continued safety of the drivers and our fans,” said Clay Campbell, Martinsville Speedway President. “We will continue to collaborate with ISC and NASCAR for additional safety enhancements deemed necessary.”
