Palm Beach International Raceway

Palm Beach International Raceway (stylized as PBIR and formerly Moroso Motorsports Park) was a motorsports facility located west of Jupiter, Florida. The facility had a quarter-mile drag strip, a 2.043 mi (3.288 km) road course, 0.700 mi (1.127 km) kart track as well as mud racing tracks. The road course at Palm Beach International Raceway was a 2-mile, 10-turn circuit constructed of hot-mix asphalt and set on an aggregate base. It was 40 ft (12 m) wide with a 0.333 mi (0.536 km) section measuring 80 ft (24 m). The Palm Beach International Raceway Drag Strip was a quarter-mile, all-concrete racing surface. One of six tracks in the U.S. built completely from concrete, it was more stable, level and consistent than asphalt. The track is sanctioned by the International Hot Rod Association (IHRA). PBIR was also home to the Palm Beach Driving Club.
