A Jughandle is used at a signed/signaled intersection, which disallows either a direct left turn or U-Turn and instead uses a right handed exit to allow access off the main roadway prior to or after the intersection and a subsequent indirect turn from the connector or cross street.
What is a jughandle
There are 3 kinds of Jughandles defined by the NJ-DOT. They are:
- Type A - Forward: Exit prior to the intersection accommodating traffic turning both right and left.
- Type B - U-Turn: Used in the absence of a cross street or at a T-Intersection.
 |

- Type C - Reverse: Exit downstream of the intersection and create a loop to meet the cross street/traffic signal.

What is not a junghandle
Exit ramps which use local streets to enable this maneuver are NOT considered jughandles.

Segment Type & Name
- Any Jughandle which is unsigned with BGS (green signs) or signed with BGS which only display the primary/alternate name of the connecting road, should be treated as a standard At Grade Connector.
- Type: Lowest connecting routable segment. Name: None.
|
Need image |
NOTE: If the segment connects and routes to 3 or more segments, the type rule changes to the same as the second highest type which can be routed to or from the jughandle. See Roundabouts for a detailed explanation of this rule which would apply here.
- Any Jughandle signed using BGS which has more than one name displayed (ie. multiple streets, community, POI) or displays the name of a road which is not directly connected, would fall under the exceptions for At Grade Connectors.
- Type: Ramp. Name: Match signage.
If the jughandle consists of more than one ramp segment (eg. forks at the interchange) at least one of the segments is required to be named. In this scenario the ramp type will hide the segment name in the client, so adding any other relevant signage - white, blue, brown (- ie. All turns, U-turn, XXX State Park) is acceptable only after the wording from ALL important BGS is added. Only add wording from signs which will help orient drivers.

Turn Restrictions
Most or all of the turns at the actual intersection - from the main road to the cross street - will be illegal. Be sure to check and disable them when applicable. Remember to review the Turn restrictions portion in the Map editing quick-start guide.
Geometry
The junction should be placed as close as possible to the start of the solid white line and the angle should be set from 10-44°. This will give the expected instruction for a jughandle of "Keep/Exit right" while giving the transition a clean look on the map. For further references that apply to both ramp and At grade connectors revisit the Junction Style Guide and Ramp geometry.
