The half-price tolls to cross the Port Mann Bridge will remain in effect until Jan. 1, when the year-long discount ends and motorists who now pay $1.50 will be charged the full $3.
Officials previously expected to open all the new Highway 1 lanes through Coquitlam and Burnaby in early to mid-December and said the discount would be eliminated at that time.
Now they say all the new lanes will be open before Christmas but the toll discount will be kept in place for the rest of the month.
About 20 per cent of regular vehicles using the bridge already pay the full $3 toll, while 80 per cent qualified for the 50 per cent discount by signing up with the TReO electronic tolling system within three months of the bridge opening last December.
Final work on the project will continue next year.
The bridge won't open the final two of its 10 lanes until next summer, when the old Port Mann Bridge will be fully dismantled and the outer lanes can be connected to the bridge approaches.
