Pattullo Bridge | Canada

Pattullo Bridge

The existing Pattullo Bridge is an arch bridge that connects New Westminster and Surrey, and provides 75,700 cars and 3,840 trucks (on average), a daily option for crossing over the Fraser River in the Metro Vancouver area. At the start of 2020, Fraser Crossing Partners (a joint venture between ACCIONA and Aecon Group, Inc.) was selected to design and construct the replacement bridge. The replacement would allow a safer, easier, and toll-free commute for local citizens.

Sixense Monitoring System

A light rail tunnel, two additional bridges (one light rail, one heavy rail), and the existing Pattullo Bridge were all located within proximity of the location of the new bridge alignment. Sixense was chosen by Fraser Crossing Partners to develop a monitoring solution that encompasses the surrounding major structures and railways, enabling continued safe use of the nearby infrastructure throughout the construction work on the bridge replacement. The comprehensive system, delivering near-real-time data, included:

• 13 Sixense patented Cyclops AMTS systems monitoring hundreds of prisms
• 5 4D-BLOC GNSS sensors
• 34 vibration monitors
• 52 wireless tilt sensors

An Ongoing Partnership

The innovative monitoring system was actively administered and maintained by Sixense, delivering near-real-time data on the Geoscope platform to all involved stakeholders. Uninterrupted, safe operation of all surrounding infrastructure continued to be enabled by Sixense through the project completion.

The New Pattullo Bridge

Once the new bridge is open to the public in 2024, the improved crossing will feature four modern, wider lanes for traffic with allowance for a potential future expansion to six lanes, pedestrian and cyclist access, and better connections to, from, and near the bridge. Sixense’s efforts were active until October 2023, as the piling works finished throughout the project.
