DEF

A curb extension or vertical barrier extending to approximately the centerline of a roadway, effectively obstructing (prohibiting) one direction of traffic.

CONT

Semi-diverter (partial street closures) limit access to a street from one direction by blocking half the street. They reduce through traffic in one direction, partially in the other and allows two-way traffic on the remainder of the street. Semi-diverters are generally effective in reducing volumes, especially if one direction of travel predominates on a street. In addition, they allow a higher degree of emergency vehicle access than full diverters.
