Infrastructure equipment and technology provider Lindsay has secured a contract from the Province of British Columbia’s Ministry of Transportation and Infrastructure in Canada to install its Road Zipper System on the Alex Fraser Bridge.

The Road Zipper System will replace an existing static concrete barrier and allow seamless traffic movement during peak hours.

Lindsay is expected to generate around $14m revenue from the project.

The technology comprises connected T-shaped moveable barriers to form a continuous wall.

Using a conveyor wheel system, the Road Zipper transfer machine re-positions the median barrier at up to 10mph to create a moveable ‘zipper lane’.

After its deployment, it will create four lanes northbound and three lanes southbound on the bridge during the morning rush hour.

“Lindsay is expected to generate around $14m revenue from the project.”

Lindsay Transportation Solutions senior vice-president Chris Sanders said: “Predicting traffic flow can be difficult, particularly if you’re looking 20 or 30 years into the future.

“The key to any design is building in as much flexibility as possible from the beginning, so you can efficiently accommodate the needs of a growing population.”

Alex Fraser Bridge, which connects Richmond and New Westminster with North Delta in Greater Vancouver, was opened in 1986.

Four lanes out of six were initially made operational for vehicle traffic, which was later increased to all six lanes moving the pedestrian and cycling lanes to the perimeter of the bridge.

The officials will re-stripe them to add the seventh lane along with the new counter-flow moveable barrier system to improve the bridge capacity and reduce traffic congestion during peak periods.
