Indeed. I'd parse it as "foam" being a verb, "spill" a noun (with "tomahawks" being attributive to it), and apparently, the brave people foamed the tomahawks spill onto the I-75 (a road?) which is either South in Cobb (which I take to be a geographical designation, perhaps a city or part of a city), or we're talking about a specific part of the I-75 that's South in Cobb.

More likely the verb is "spill", and foam tomahawks of the Braves variety (that is, pretend axes made out of "foam" associated with fans of, or perhaps overtly branded with the branding of, a sports club called the Braves) spilled on onto the road.
I was helped massively there by cultural context - knowing that "braves" and "tomahawks" are often associated, that lots of American sports fans are weirdly and enthusiastically racially insensitive*, and that sports fans, particularly in america, often wave large plastic replicas of things.
I was considerably not helped by the lack of an apostrophe on the first word, which points away from the above interpretation. However, on consideration "Braves" can be just a modifying noun - if, say, it's a factory or warehouse full of foam tomahawks that has exploded, intended for but not actually yet aquired by Braves fans, it's probably OK to call them "Braves tomahawks" rather than "Braves' tomahawks".
I was also not helped by the word "foam", which here is being used in a weird sense, I assume, for a solid plastic substance filled with air pockets that is definitely not foam in the normal sense. It is a standard usage - we also talk about 'memory foam' mattresses for instance - but it's not what comes to mind for the word "foam" outside of certain limited contexts (I'd rarely say "pass that foam", for instance, to mean plastic, though I might say "pass that polystyrene foam").
*I'd be fine with a club calling itself the "Redskins", if they used it as the basis for outreach and representation. But calling a club the "Braves", and having fans dress up as "braves" and wave "tomahawks" around... it's only one step away from calling them the "Minstrels" and having the fans all wear blackface.
