I like it. It's definitely the right direction and is certainly functional.
It would be nice on the highway browser page, if there could be links to the region and system, rather than going back to the main HB page.
Also good, especially for the new users, would be a page with systems (country, code, name, description?, tier, status, HB link) and another with regions (something like a table with: Continent, Country Code, Country Name, Region Code, Region Name, HB Link - that one would be a bit harder to do as it is more than one table to use), to use as springboards for highway browsing.
Sortable tables would be very useful too.
One thing I note is that we are lacking many shields (I can see US, I- and AZ routes) and haven't got banners sorted.
