Damaged Bush help needed

Is there anyway I can recover this bush, I don't want to chop it down as it would make a big hole in the hedge. I was here when I took over the garden. I think this is a result of salt used on the path alongside in winter, but has not affected the rest.

It looks like Leylandii, so no, once they get to that stage (ie, dead), it won't recover.

 

That looks like a dead conifer to me, Simmel.
There's no way back from the dead.
I would cut it out and hope the surrounding conifers will just grow into that space. I think they will.

 

Thanks, shame really, I will try to cut out the dead brown branches from both sides and keep the few green ones that are still growing and see what happens.
