The Split Centerline tool is one of the centerline feature class editing tools available in Esri Roads and Highways. If you want to create a route that does not span the complete centerline, use this tool to split that centerline into two contiguous parts. Esri Roads and Highways supports splitting a centerline by clicking on it at a specific location as well as splitting a centerline relative to a measure location on a route (see Splitting a centerline by measure). Generally, the Split Centerline tool will be used to split a centerline relative to some feature being snapped to, like an intersection, county boundary, railroad crossing, or some other feature.
- In ArcMap, add the centerline and the network layers to the map.
- Start an edit session and zoom to the centerline that you want to split.
For more information on how to start an edit session, see About edit sessions.
- On the Roads And Highways Editing toolbar, click the Split Centerline button .
- Click a point on the centerline where you want it to split.
The centerlines on both sides of the split location flash in dark green and the centerline splits into two parts.
