Highways, Roads and Bridges - As enacted, authorizes a county or municipality to request the department of transportation to conduct a highway traffic noise study for residential properties located along the sound propagation path of a state or interstate highway if certain criteria are met. - Amends TCA Title 4, Chapter 3 and Title 54.

SB 2027 allows Tennessee counties or municipalities to request a state highway traffic noise study for nearby homes when trees (a "tree zone") are removed behind those homes for reasons unrelated to highway construction, and no existing noise barrier or natural shielding is present. It directly affects residents living adjacent to state or interstate highways who experience increased noise after tree removal. The bill requires a local government resolution to trigger the study, which assesses noise impact without mandating a solution. This policy change provides a formal process for communities to evaluate noise concerns after tree-clearing events.
