travel through (something or some place)
1. To move or journey in one side of something and out another. We'll be traveling through a long tunnel shortly, so you won't get any reception on your cell phones for a while. We should travel through the forest to reach the camp quicker.
2. To move or journey around or across something or some place. The crew will travel through space for nearly three months on their way to Mars. I'm traveling through France on my way to Spain.
3. To move or journey among or between something. I'd been traveling through the trees for some time with no sign of the village anywhere. Unfortunately, there was no way to avoid traveling through the gloopy mud.
4. To move or journey during a particular kind of weather. We were traveling through such thick fog that we could barely see a foot in front of us. You should never travel through a lightning storm on foot.
