I have a couple of downspouts that drain into a 4 inch black corregated drain pipe that runs underground from the downspout out to the street between my and my neighbor's driveways. It surfaces at the street level and I am looking for some way to protect it from the neighbor's teenage daughters driving over it and smashing it. Also, since I would have to cut about 3 foot off of it and replace that section, I need to know if there is a coupling that will allow me to do this. I thought of trying to find some kind of metal channel I could put over the top of this drain line to protect it, but can't find anything. Any help you can offer would be appreciated.

Thanks.
