About this project

In 2009, the Quebec Ministry of Transportation embarked on the reconstruction of the southern structure of the Galipeault Bridge on Highway 20, between Ile-Perrot and Montreal. As the structure was demolished, all eastbound traffic was redirected to the northern structure where a reversible lane was put into place using a movable barrier which allowed optimal use of the available 3 lanes for the duration of the project. Lane configuration was changed twice a day, 5 days a week. All lane closing and opening operations were conducted safely with the push of a button using a series of Automated Warning Signs (SwiftSign) and Automated Warning Gates (SwiftGate).


  • The project requires important daily traffic operations for a 2 years period which can translate to high traffic control costs and time-consuming operations
  • Long periods of winter conditions
  • Need reliable and robust temporary solution


Versilis worked hand in hand with the Quebec Ministry of Transportation, the design engineers, and the contractor to install a solar-powered automated lane closure solution at both ends of the movable barrier. A total of 14 automated warning signs (SwitfSign) and 12 automated gates (SwiftGate) were installed. All lane closing and opening operations were conducted in safety with the push of a button using the SwiftGate system. The automation eliminated the need to have workers deploying and dismantling traffic signs and drums in live lanes. A step forward in highway safety and a low-cost solution.


  • Increased daily traffic operations efficiency
  • Increased lane closure visibility and motorist safety
  • Reduced highway worker exposure to live traffic
  • Overall reduced project traffic control costs
  • Quick install and easy relocations of the product as the project progressed
