Unsplitting connected polylines

The Unsplit Connected Polylines tool is used to unsplit connecting features. Only features that are touching endpoint to endpoint and have the exact attribution on editable fields are unsplit. You can use this tool to merge features that are in the same network or create a polyline feature from two separate line features. For instance, you can create a single road feature using nearby roads that have similar attributes.

Two roads are merged into one feature
