Removable barrier
First Claim
1. A retractable barrier adapted to cooperate with an intermediate passageway in a fixed median barrier serving as a partition between a first traffic lane and a second traffic lane, said retractable barrier being adapted to move between an open position and a closed position whereby said intermediate passageway is either open to permit traffic to move through said passageway between said traffic lanes when said passageway is open or is closed to prevent traffic movement through said passageway;
- said retractable barrier comprising at least one movable barrier member nd fixed holding means arranged in said intermediate passageway to which said at least one barrier member is retained to resist vehicle impact when said retractable barrier is in said closed positions and acting as a guide during movement of said at least one barrier member towards said closed position.

Abstract
A removable barrier adapted to co-operate with a concrete median barrier of a roadway to form, in situ, a barrier between a vehicle travelling in one direction on the roadway and a vehicle travelling in another direction, wherein:
the removable barrier is adapted for movement such that, when desirable, the vehicle travelling in the one direction can transgress the barrier and travel on the opposite side of the roadway, and further wherein
the removable barrier comprises at least one shell conforming substantially to the outer shape of the concrete median barrier and is adapted for sliding movement relative to the concrete median barrier.
