In Paris there are famous bridges to stroll under
I was thinking
À Paris il y a des ponts sous lesquels on peut flâner
The wider issue here is, how is it best to say phrases such as
Your translation is correct (apart from missing the translation for famous, but I guess that's not the point here). As for the other phrases, they respectively translate to

sous lequel
sur lequel / au-dessus duquel
dans lequel
au travers duquel
You'll just have to replace lequel or duquel with the agreed form if needed
lequel / laquelle / lesquels / lesquelles
duquel / de laquelle / desquels / desquelles
