CDOT SLD (Straight Line Diagramming)

Straight Line Diagram Tool

The primary function of the SLD (Straight Line Diagram) application is to display selected information along a segment of a highway or corridor. The user chooses a segment by specifying a route and milepost interval, then selects the desired roadway information to be symbolized in the diagram. The information is organized into groups based on discipline (i.e. environmental, geometrics, traffic, etc.), enabling the user to easily compose the desired diagram. Combined with the diagram is a smaller map view of the highway segment highlighted in red.
