When specifying height or weight or other parameters and you see that StreetComplete highlights a longer than necessary part of a road, it's best to go into "other answers", select "differs along the way" and it'll bring you to a simple UI where you can split/cut a way into smaller pieces.
Doing that will allow you then to tag height or whatever only to sections where it actually applies.
