AVONDALE, Ariz. (AP) -- Phoenix International Raceway will undergo its first major track paving project in 20 years after hosting the first of its two NASCAR races later this month.
The 1-mile oval also will undergo slight configuration changes officials hope will increase speeds at the track 2 mph to 3 mph and promote more side-by-side racing.
The changes will include a widening of the front stretch, installation of concrete pit stalls and implementation of variable banking so there'll be immediate use of two racing grooves.
Construction will begin after the Feb. 27 NASCAR race and is expected to conclude in September. PIR's second NASCAR race is Nov. 13.
