The eastbound Highway 1 off-ramp for 152 Street in Surrey is switching back to the right side of the freeway tomorrow.
The exit lane had temporarily been on the left side of the highway since January while crews built the new, permanent off-ramp on the right side.
Motorists heading east over the Port Mann Bridge are being advised of Tuesday's exit change – which happens at 5 a.m. – with updated signage and electronic message boards.
Drivers are urged to use caution and pay close attention at the Surrey end of the bridge as traffic adapts to the exit's new location.
Transportation Investment Corp. spokesperson Pam Ryan doesn't anticipate the change will be challenging for motorists because it's a return to the usual traffic pattern.
"If they miss the exit then they can take the exit at 160th," she said.
The Port Mann/Highway 1 project includes 37 kilometres of highway widening from McGill Street in Vancouver to 216 Street in Langley.
Crews are rebuilding seven highway overpasses and nine interchanges.
Eight of the 10 lanes of the new Port Mann Bridge are slated to open this December and minimum $3 tolls will start at the same time.
Construction to finish the entire project, including the final two bridge lanes, will continue through 2013. The old bridge is to be torn down in 2014.
