KEY: N = data do not exist; R = revised.

^a A Type I barrier is built on a new highway project or a physically altered existing highway.

^b A Type II barrier is built to abate noise along an existing highway (often referred to as retrofit abatement) and is not mandatory.

^c All other types of barriers are nonfederally funded.

^d Have not been assigned a year of construction or a cost.

NOTES

Twenty-eight miles of barriers, while assigned a year of construction, cannot be assigned a cost. Data are produced on a 3-year cycle.

California and Arizona did not provide data for the years 1999, 2000, and 2001 and therefore these years may not be comparable with previous years.
