Until October 3, the Pattullo Bridge deck will be under rehab construction to keep the roadway safe. Only two lanes will be open during the five months of work. You can still use the bridge, but obviously this will impact your travel times and your trip planning around the lower mainland.
Visit the bridge closure and construction schedule to plan ahead.
