Noise Walls Home Page
2023 LiDAR
Each linear feature represents a noise wall that follows or is detectable from the State Highway System. These linear features are placed on the top of walls and generally follow continuous walls for their full extent.
When a continuous wall follows a road/highway for a portion of its length as well as an associated entrance or exit ramp, the feature will be segmented where the ramp converges/diverges. The dashboard for these features includes all extracted features, even those following routes off the State Highway System.
Please note that obstructions caused by trees, topography and structures (including other noise walls) sometimes prevented detection and extraction of a wall's full extent. The Overlap attribute field indicates which noise walls were found to overlap each other.
