Lost and Found Assault missing bridge

I am working on completing Assaults for Captain rank and I am unable to finish Lost and Found. When I head north on the map at H-6, the bridge to cross to the North West is not there for me to cross. If I walk back and give it some distance, the bridge comes in to view, but when I get closer and even right next to it, I am unable to cross over the bridge because it disappears. Unable to complete the assault without being able to cross the bridge.

Nevermind. I was mistaken and there is no bridge there to go to the north. It clips in and out though depending on the distance you are standing from the bridge. Might just be something else wrong with my computer
