Searchable streets problem

I have a map search with whole city searchable by streets.
what I did is I made each seperate search streets movie. my swf size for each movie is about 150 kb. The # of streets are around 250+. So you could just imagine how much space it would eat up.
Is there a way where I only have one main movie and the searchable street would load in the main movie.

hope you have available similar sample for this type>

thanks in advanced!
