Those heading to the United states over the next 48 hours will face delays when heading to the north portal crossing.
The crossing will be down to one lane going north and south until at least Friday.
Communications Officer with Canadian Border Security Agency Luke Reimer said the delays are caused by construction.
“The work to be completed would block Canada-bound traffic from proceeding north, so from the CBSA building, passed the north portal duty free for a stretch of about 230 metres, both north bound and south bound traffic will share the two highway lanes that are normally reserved for south bound traffic only.”
Reimer said there’s been work done at the north portal since May.
“So since May, new licence plate reader equipment was installed in the traffic lane at north portal, road base has been added, and the new primary inspection lane area is in the final stages, with concrete pavement planned to be poured shortly.”
The CBSA is advising travelers to use the other portals until Friday, when the north portal will not be as backed up.
