If you want street maps at that level you need to look at the local government or county webmaps out there. NAtional government sites don't maintain that kind of level of accuracy in the public realm. Try getting a tool like Geomedia Viewer and load some webmap services (see geographynetwork.com) and another good one is the WMS Viewer - a great example of what you can do with OpenSource GIS ... The Intergraph WMS Viewer (wmsviewer.com) facilitates collaboration of geospatial information stored in WMS sources. The thin-client Web-based application enables users to view one or more WMS servers accessed through Web sites that conform to the WMS interface standards defined by the OGC. Details here
good luck
