The Pattullo Bridge will be closed in all directions at the end of the month for seismic testing.
The closures will take place overnight on Friday, January 31 and Saturday, February 1, from 9 p.m. until 5 a.m. The bridge will be temporarily closed during these times for the testing of a recently installed early seismic warning and wind monitoring system.
鈥淭he system鈥檚 sensors are designed to detect early warning signs of a significant high wind or seismic event,鈥� said a news release. 鈥淯pon detection, traffic control gates, similar to those at railway crossings, will block the bridge entrances. The system will also initiate advanced warning lights and digital bridge closure signs alerting bridge users of the closure. The system will be ready for activation upon successful testing.鈥�
Installation includes:
- Seismic activity and wind warning sensors
- Bridge closure devices
- Advanced warning lights and signs
鈥淧attullo Bridge users are encouraged to use the Port Mann or Alex Fraser bridges as alternatives during the closures. N19 bus trips will be re-routed over the Queensborough Bridge during the closures. Affected customers should plan for an additional 30 minutes of travel time. Emergency vehicles will be able to cross the bridge in both directions at all times.鈥�
