Notes:

Miles of noise barriers can neither be assigned a year of construction or a cost.

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

Description:

KEY: 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.
