Metro Vancouver commuters saw major changes Monday morning on Highway 1, after the 152nd Street off-ramp in Surrey jumped from the right side to the left this weekend.

Saturday night's construction also saw road lines removed and repainted, new signage put up and highway barriers repositioned.

The reconfiguration is part of the Port Mann Bridge Highway One Improvement Project, a 37-kilometre infrastructure development scheduled to be completed in the winter of 2012-2013.

The project involves replacing, upgrading or adding more than 30 interchanges and overpasses from the McGill Street Interchange in Vancouver to 216th Street in Langley.

The 10-lane toll bridge will also double the capacity for commuters crossing the Fraser River per day.

The temporary off-ramp switch will give more room for construction workers to rebuild the 152nd Street exit with limited traffic disruptions.
