Infineon Raceway to Repave Road Course in August

SONOMA, Calif. – The sound of roaring engines will go silent at Infineon Raceway when the track closes for nearly three weeks in August to repave the 12-turn, 2.52-mile road course.

Repaving will begin immediately following the NHRA FRAM Autolite Nationals on Monday, Aug. 4 and is expected to be completed by Aug. 20. The $1 million project will include repairing and stabilizing the existing pavement, adding new drainage to eliminate seepage problems and repaving those portions of the road course that have not been resurfaced over the last two years.

The track will be resurfaced with polymer-modified asphalt that is designed to withstand the constant usage – Infineon Raceway features 340 days of on-track activity each year. Segments of track already repaved over the last two years – Turns 4-5, 9-10, 12-1 and the Chute – will not be repaved.

“At the core of everything we do is one of the world’s most challenging racing circuits,” said Steve Page, Infineon Raceway president and general manager. “With the completion of this new track surface, we’ll offer a road racing facility that is second to none.”

The track repaving comes on the heels of the extensive three-year modernization plan that has transformed the facility into one of the premier road-racing, drag-strip and entertainment venues in the country. Some of the improved amenities fans have experienced include a new permanent grandstand at start/finish, hillside terraces around the perimeter of the raceway, underground pedestrian tunnels, a 16-turn go-kart facility, a new system of shuttle roads and a new drag strip, complete with a 660-foot concrete launch pad and permanent separation of the road course from the drag strip. There have also been several safety improvements, including increased runoff at virtually every turn, and pit stalls to accommodate a 43-car starting grid.
