    TommyGavin99Very good job on the video. Ik it's annoying when the trophy symbols go off the map. A way to improvise would be to pause the game after flying under a bridge, then setting a waypoint w/ the next trophy.

    Brett Evans15Hey guys, I did checked the stats and it’s still good because It doesn’t count to 100% on both of them in 5 Helicopter Tours and 14 Bridges to get two achievements is Sightseer and Under The Radar.

    Not sure if it's solution but it might help.

    If you flew under all 14 bridges and the achievement didn't pop out then it's possible you didn't fly right under the first bridge (from the sea) in Alderney’s industrial park. It counts if you flew under it right from smokestack. First I flew the bridge under the water and it didn't count.

    SledgeHammer jrSame here. Utterly ridiculous that only one specific part of the bridge counts towards the flyunder total, but there you go.

    Thanks for the tip.

    To obtain this achievement you need to fly under all 15 main bridges in liberty city. So you must go through all of liberty city bridges and when go under the right bridge on your top left corner there will be a text saying "14 more under the radar bridges or something like that. Good Luck! P.S I do have this achievement
