CTRMA Using Zipper Barriers to Expedite MoPac Work

KEYE reports that the Central Texas Regional Mobility Authority is now using zipper barriers to help speed up its MoPac project. The barriers allow workers “to come in at night, shift the barrier over to close off a lane and then in the morning to come back and put it along the shoulder,” CTRMA spokesperson Steve Pustelnyk tells the station. The report adds, “The barriers are different because they can be moved. A machine drives over the spaced, spine-like barriers and moves them one lane over. It’s a concrete barrier that can be moved quickly.”
