How can I get rid of trumpet vine?

I am on a city lot, and I was given a red trumpet vine some thirty years ago. I let it grow up a tree stump, looked good-mistake. It grew up on my fence, and again, I thought it looked nice...mistake again. Now, after years, it seems like I just can't kill it. I pull it, I cut it, and still it grows. It runs underground on roots as strong as cables. Any idea how to bring this fierce beast down? It's a constant battle, and the trumpet vine is at least holding its own, and maybe winning.

    IF you have no objections to the use of to your local garden center about your vine problem, they will sell you an herbicide that will take care of it down to the roots. NOTE: Most people start removing the wilted vine before it has completely died-mistake...when that happens roots are left in the soil & the problem returns 10 wait until the roots are dead before removing the main trunk of the vine.
