Winter operations forced the Port Mann Bridge to close in both directions Thursday night.
It reopened around 6 a.m. Friday but the eastbound HOV lane will remain closed for winter operations, according to Drive BC.
The Ministry of Transportation put out a notice Thursday afternoon, warning the bridge could be closed if the weather continued to worsen.
“The ministry uses a cable-collar system to remove snow that builds up on the cables of the Alex Fraser and Port Mann bridges, so that traffic can safely pass,” it said in a release.
“The cable collars were successfully deployed overnight and this morning. However, with warming temperatures and windy conditions, snow and ice can shed onto the travel lanes.”
The Alex Fraser Bridge was also closed Thursday for winter maintenance but has since opened. The southbound right lane will remain closed for winter operations, according to Drive BC.
