KEY: R = revised.

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

^bA 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.

^dHave not been assigned a year of construction or a cost.

NOTES

Miles of noise barriers can neither be assigned a year of construction nor a cost.

Miles of barriers, while assigned a year of construction, cannot be assigned a cost.
