Sixty 10-foot long sections of movable barrier wall were precast and assembled on the job to separate the work area from the travel lanes, in a project which consisted of the replacement of an exterior prestressed concrete I-Beam together with a portion of the deck and handrail on the Florida Turnpike bridge. When installed, the barrier sections are tied together near the base by chain or cable to form a continuous unit. The temporary barrier was placed on the side away from the driver. Two lanes of traffic were maintained by reducing the width of the lanes through the work area. To date there has been no accidents where a workman has been injured. To date, the bid item for the temporary barrier wall has included the cost of construction of the wall sections plus moving, resetting, and final storage of the wall sections. This wall concept for traffic maintenance and safety has been used on several major reconstruction projects through the state.
