Maintenance work is taking place on the Canadian side of the Ambassador Bridge.
Crews can be seen repairing the ramp at Wyandotte and Huron Church.
Bridge Spokesperson Stan Korosec says crews are doing what's called "full depth repairs" stating it's a good time to do the repairs since traffic is slow.
A caller to AM800 news this morning indicated it looked like a sinkhole but Korosec says that is not the case.
