How can I dissolve the lines for my roads and make one outlined polygon

[ssfsfgsefg]

I have the roads that I want to just display at outlines but not segments (I.e not disconnected from each road).

I am trying dissolve but its not working. Attached is a link to a package file of the data. Please help! https://www.dropbox.com/s/55hqr9471v9qxwf/Road%20Test%20packa[ATTACH=CONFIG]34775[/ATTACH]ge.mpk

You  may want to include a little more descriptive information: for example are you  dissolving on an attribute that is common between all the streets, like "NAME" or something obvious like that?
