I have a street road way shape file (polylines) that I want to create a polygon around the outer exten of it so I can display it on an aerial and set the transparancy so the proposed road way pops out rather than is a linear feature.  I have tried a buffer and that does nto work.  The way that I have been doing it is within CAD I have to close the lines and create a closed polygon, which is extremly time consuming.  Is there a way to create a boundary that follows the outer extent of my road way and creata a polygon?  This way I could over lay my line work on the polgon so that it would pop out.  I have attached a small sample dataset.  Thank you

Have you tried the Minimum Bounding Geometry tool? It's under Data Management and should do almost exactly what you're asking, or at least get close enough that a few hand edits would finish it out.

yeah that does not work it quicker to do it in CAD.  Thank you.

How about changing your display/symbology settings for the line?
