Lateral thinking puzzle: woman on the bridge

[soxfan[$]]

Hopefully this one will take a little longer than the last one:

During WWII, there was a footbridge over a ravine between Germany and Switzerland. It was guarded by a German sentry. His orders were to shoot anyone trying to escape over the bridge, and to turn back anyone who did not have a signed authorization to cross. The sentry was on the German side of the bridge. He sat in a sentry post, and came out every three minutes to survey the bridge.

There was a woman who desperately needed to escape from Germany to Switzerland. She could not possibly get a pass. She knew that she could sneak past the sentry while he was in the sentry post, but it would take between five and six minutes to cross the bridge. There was no place to hide on or under the bridge, so the guard would be easily able to shoot her if he saw her on the bridge escaping to Switzerland. How did she escape across the bridge?

did she sneak past the sentry when he was in the tower, then turn around and pretend that she was coming into Germany, and get turned around back to Switerland because she didn't have a pass to enter Germany?

And here I was going to ask whether she climbed down the ravine! Way to go, worm!
