Traffic was at a standstill coming off the Ambassador Bridge into Windsor on Saturday.

"There's nothing I can do about it. We're held captive by the city," says one distraught truck driver.

Transport trucks along with regular traffic was detoured to Wyandotte Street west down Crawford to Tecumseh Road West and then back to Huron Church Road.

On an average day, the detour adds about 10 minutes onto the commute.

On Saturday that that doubled.

"We worked really closely with the city of Windsor, Windsor PD and the contractor to ensure the detour worked very efficiently," says Randy Spader of the Canadian Transit Company.

Southbound lanes off the Ambassador Bridge were closed to replace the railroad tracks intersecting with Huron Church.

"Over the years the tracks have deteriorated, rusted and the head of the rail separated from the web, so it cracks. So when the train goes by it could leave the tracks," says Richard Gouin, signal maintainer.

During the closure, the Canadian Border Services Agency was reporting a 30 minute delay.
