This 12-mile segment of I-30 TEXpress Lanes was built to provide two reversible, barrier-separated HOV/managed lanes on the Tom Landry Freeway. The facility is located between the non-tolled general-purpose lanes, accessible via four entrance and exit points, often referred to as reversible slip ramps. As part of this project, Versilis was selected to supply 110 crash tested automated warning gates, or automated barricade gates (ABG), to control the different access points.
Reversible slip ramps are equipped with a number of automated warning gates on each side of a final Vehicle Arresting Barrier (VAB). The warning gates warn drivers not to enter the slip ramps when the traffic pattern is in the opposite direction. Should a vehicle go through the warning gates, it is stopped by the VAB.
While the crashworthiness of the Versilis gates was an essential feature for the Texas DOT, the product’s narrow footprint was also critical. The ability to mount swing gates on top of a narrow barrier wall was an important benefit since the project had to be done without any additional right-of-way or restrictions of access to existing residences or businesses. All warning gates can be controlled locally or remotely from the Traffic Management Center.
