DETROIT — Truckers and travelers are reporting some of the longest cross-border lineups they’ve seen since the days immediately following the terrorist attacks of Sept. 11, 2001.

Increased inspections at several Canada-U.S. border crossings this summer has led to longer than normal wait times, according to an Associate Press report.

The wait to cross became so long this month at Blue Water Bridge, which connects Port Huron, Mich., with Point Edward/Sarnia, that the Ministry of Transportation in Ontario set up portable toilets along the road.

Motorists and commercial drivers are not expecting the delays, said Garry McDonald, president of the Sarnia Lambton Chamber of Commerce, which requested that portable toilets be set up leading to the Blue Water Bridge in Sarnia.

According to the Peace Bridge at Fort Erie-Buffalo, the time it takes U.S. Customs officers to inspect a vehicle has risen from 54 seconds last year to about 75 seconds this year.

“Obviously something happened, some sort of policy directive that has resulted in longer processing times,” Ron Rienas of the bridge authority told AP.
