Temporary Movable (“Zipper”) Barrier systems in work zones
New York has used movable concrete barrier. The New York Thruway Authority has a permanent movable barrier operation on the Tappan Zee Bridge carrying I-87 and I-287 across the Hudson River. Lanes are reversed in AM and PM peak periods using the movable barrier every day to enhance capacity.
NYDOT has used the movable barrier on construction projects in the New York city area. Details are not available but the transfer vehicle and storage for it must be considered. The design details are probably worked out in consultation with the manufacturer or vendor. It has been very successful.
