As you can see in the Trick Shot Loading Screen below, the Fortnite ‘T’ location is hiding underneath a bridge in a wooded area.
This clue is going to take us to the bridge that is over the river that runs through Weeping Woods. The exact Fortnite hidden ‘T’ location can be seen on the map below.
As you land at the location, you should find the hidden Fortnite letter resting underneath the north side of the bridge.
You won’t be able to search the hidden ‘T’ until you have completed ten of the Week 7 challenges.
