As noted in a trivia item, the arrow that Carter actually accidentally shoots toward Hogan is not the arrow that he was first playing with. The fletching (feathers at the end) changes between the time Carter first pulls the arrow out and the time he actually shoots the arrow. The fletching on the first arrow is much larger and rougher than the neatly tapered fletching of the arrow he actually shoots.
Near the end, Schultz has the Indian feather on his head and Klink comes out of his office. Klink stands at the door with nothing in his hands and cups them together in front of him. The camera angle changes and now Klink has his swagger stick under his arm and one hand on the head of the stick.
The bridge that is shown being blown up bears no resemblance to the bridge Newkirk previously walked across and the truck drove onto. Not only that, there is no sign of the truck on the exploding bridge.
When shooting the arrow at the truck, the first arrow that Carter prepares and shoots is not the arrow that hits the window frame. The arrow that Carter actually shoots has the large fletching (feathers), while the arrow that hits the window frame has the smaller, tapered fletching (probably the same one that was used earlier, when Carter accidentally shot the arrow at Hogan). Then, when Newkirk takes the arrow out of the window frame and shoots it, it is back to the large, rough fletching.
Carter sets the fuse to blow the explosives when a ton and a half (3,000 pounds) truck crosses. A one and a half ton truck doe not weigh a ton and a half it can carry a ton and a half of cargo. In fact an average sized car weighs at least a ton and a half.
The river is actually the Dussel River. Dusseldorf is a town on the Dussel River, where the Dussel meets the Rhine.
Kinchloe says at one point that German trucks are limited to 35 miles per hour in rear areas. At that time, Germany was on the metric system, not the English system. The number should have been 60 kilometers per hour.
Update: While the Germans would certainly have indicated the speed in Kilometers per Hour, the prisoners (at least Hogan and Kinchloe) would think in terms of Miles per Hour, particularly when doing the calculations to determine how far to lead the truck when they shoot the arrow at it.

Towards the end when they are having nighttime rollcall, as there are patches of what is supposed to be snow on the ground and the prisoners are moving a round trying to stay warm, it's obvious the impression is its supposed to be winter time yet you hear crickets in the background. Crickets are not out during freezing winter temperatures.
When Newkirk fires the flaming arrow, it hits the canvas of the truck and bounces off, yet it still sets the entire canvas cover on fire. The only way this would have happened is if the canvas had been covered with some kind of accelerant (gasoline, kerosene, etc.).
In several scenes, a production light was reflecting off of Klink's monocle.
