The event, which starts today and runs until Aug. 24, involves a number of special events on both sides of the border that will result in higher traffic volumes, said Michael Saucier, the CBSA's chief of operations.
Extra officers and temporary inspection lanes will be in place to help process extra travellers during peak times, said Saucier.
Still, traffic will be heavy, particularly on the opening and closing days, as well as Aug. 15, when the Tintamarre is held in Madawaska, Maine, he said.
Traffic will be banned on the bridge connecting that community with Edmundston, N.B., on that day, said Saucier.
"The bridge will be restricted to pedestrians starting at 1 [p.m.] going to the U.S. and cars will be able to return to Canada until 3 [p.m.] Canadian time," he said.
"And after that, until 3 a.m. on the morning of the 16th, the bridge will be restricted to pedestrians only to allow the participants of the Tintamarre and the shows to return to Canada by foot."
The CBSA has added the Edmundston, Grand Falls, Clair and St. Leonard border crossings to its online wait times site.
"So that means that the travellers can access our website through their iPhone or whatever and get the actual border wait time at these crossings in order to determine which one will be the fastest," Saucier said.
