(54) Wrong-way traffic safety barrier
(57) A safety barrier is provided to prevent wrong-way traffic from entering a one-way street. The barrier is formed by one or more metal pans which extend transversely across the roadway. Each pan is hinged to the roadway on its longitudinal side which is first encountered by vehicles moving in the normal direction of traffic flow. Spring means are provided underneath the pan for normally holding the pan in an angled, elevated position. The other, normally elevated longitudinal edge of the pan is provided with a downwardly turned flange which is clearly visible to traffic approaching from the wrong direction, and gives the appearance of a curb.
