Recreating StreetMap Network Dataset

I've been using the network dataset that came with the StreetMap data for most of my Network Analyst work. It works well and saved me from having to create my own network dataset up to this point. My only issue is the fact that the network is so large my analyses are taking too long. My original plan was to use the Dissolve Network tool to make the network more efficient. This does not work however because the network dataset is read-only.

I have two questions. First is there any work-around that will let me make changes to this read-only dataset, perhaps creating a second copy, or do I have to create my own network dataset? If I do have to create a new network dataset, is there any documentation detailing how the StreetMap network dataset was created in the first place?

Thank you in advance.
