Lowell, you're right there are two different things, there's the calle(=street) Boadilla del Monte, Urgel area; and the carretera(=road) to Boadilla del Monte, the suburb, which seems to be what you're looking for, and it's near La Casa de Campo.
There are many sites you can check, here are two of them: callejero.terra.es &
www.guiademadrid.com Hope it helps.
HAVE A NICE WEEKEND EVERYONE!!!
