Changes are coming to the intersection where St. John's Street, Barnet Highway, Ioco Road and Dewdney Trunk Road meet.

Port Moody is hoping changes to the intersection where St. Johns Street meets Dewdney Trunk Road will ease congestion and improve safety for pedestrians and cyclists.

A year-long pilot program that will see the closure of the right turn slip lane from Dewdney Trunk to St. Johns as well as other modifications could be in place as soon as Saturday, Nov. 2, according to a news release.

Council approved the trial in May to address ongoing concerns about the busy intersection, especially as motorists turning from Dewdney Trunk immediately try to cross three lanes of traffic to be able to make a left turn just a little further east at Ioco Road.

Other changes include:

  • prohibition of right turns from Dewdney Trunk during a red light
  • conversion of the two existing left-turn lanes on Dewdney Trunk into a single lane for left turns and another for right turns
  • modification of the traffic signals at Dewdney Trunk and St. Johns as well as at Ioco Road and St. Johns
  • installation of plastic lane delineators along the eastbound left-turn lane on St. Johns at Ioco Road so motorists planning to make a left turn onto Ioco Road will have to access the left-turn lane where St. Johns intersects with Dewdney Trunk

Port Moody traffic engineer Nobinur Rahman said the plan to be implemented is one of four the city considered following extensive modelling of traffic patterns through the busy corridor. He said it’s hoped the changes will motivate motorists to change their behaviour and avoid using Dewdney Trunk Road to get to Ioco Road.

The pilot project is budgeted to cost up to $80,000, with the money coming from the city’s transportation reserve fund.

The changes will be monitored by staff with any necessary adjustments to be made along the way.

Their findings will be shared with council in the fall of 2025 to determine a permanent solution.
