CT Buffered Road

Metadata Updated: February 9, 2024

Connecticut Buffered Roads is 1:24,000-scale base map data. This layer is intended to be used with the Roads and Trails layer to reproduce the cartographic symbology established by the USGS for printing roads and trails on the 1:24,000-scale, 7.5-minute topographic quadrangle maps. Cartographically, the Buffered Roads layer is used to assign thin, black line symbology to the edges or curb lines of paved and unpaved roads on the quadrangle maps. Paved roads are symbolized with a narrow solid black line. Unpaved roads are symbolized with a narrow dashed black line. Complementing this symbology, the Roads and Trails layer is used to assign line symbology that 'fills in' the corresponding buffered road area with solid red or dashed red line work, depending on road class. Line symbology should be assigned to Roads and Trails features with AV_LEGEND attribute values equal to Primary Route (wide solid red), Secondary Route (wide dashed red), and Trail (narrow dashed black). Used in combination, Buffered Roads symbology outlines the centerline-based symbology applied to the Roads and Trails layer. For base map purposes, use this layer with other 1:24,000-scale base map data such as Hydrography, Railroads, Airports, and Towns. The Buffered Roads layer includes information within Connecticut and is derived from the Buffered Roads Master layer, which reproduces all buffered road features depicted on all of the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps that cover the State of Connecticut. This layer is a cartographic product and should only be printed on maps at 1:24,000 scale (1 inch = 2,000 feet.).

Connecticut Buffered Roads is a 1:24,000-scale, feature-based layer of paved and unpaved roads on the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps for the State of Connecticut. This layer only includes features located in Connecticut. This layer is cartographic in nature. It is designed to be used with maps printed at 1:24,000-scale that require road symbology similar to the standard established by the USGS for 1:24,000-scale, 7.5 minute topographic quadrangle maps. Two layers, the Buffered Roads layer and the Roads and Trails layer, are used together for this purpose. Buffered Roads features are linear and run parallel to the road (centerline) features of the Roads and Trails layer. Buffered Roads is a set of parallel lines 50 feet apart that result from a buffer on each side of the Road and Trail (centerline) features by a distance of 25 feet. A width of 50 feet is applied to all roads, regardless of road class, and does not reflect actual pavement width. The Buffered Roads layer does not include features on the topographic quadrangle maps that appear as single lines such as hiking trails, small private roads, and old railroad grades. These features are found in the more complete Roads and Trails layer. The Buffered Roads layer is derived from information from USGS topographic quadrangle maps published between 1969 and 1984 and does not represent the road network in Connecticut at any one particular point in time. The layer does not depict current conditions and excludes many roads that have been built, modified, or removed since the time these topographic quadrangle maps were published. The layer includes buffered centerlines for Interstate highways, US routes, state routes, local roads, unpaved roads, traffic circles, bridges, cul-de-sacs, etc. Trails are not included. Features are linear and approximate road curb lines at 1:24,000 scale. Attribute information is comprised of codes to cartographically represent (symbolize) paved and unpaved roads on a map. This layer was originally published in 1994. The 2005 edition includes the same road features published in 1994, but the attribute information has been slightly modified and made easier to use.
