Display Field: ROUTE_NAME

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This dataset contains single points representing the ADA curb ramps located on interstates, ramps, state routes, TDOT maintained state park roads, and locally owned NHS routes in Tennessee. This dataset can be queried by either location information, ramp slopes and widths and lengths, presence of truncated domes, or by ADA curb ramp type. These records were derived from vehicle mounted LiDAR sensors and digitally captured photos. This information was collected by Cyclomedia Technology, Inc. under the direction of the Asset Management Division and the Long Range Planning Division. Questions on this dataset should be directed to TDOT.Maint.AssetManagement@tn.gov.
