I think the Eugene City gas tax is 5 cents/gallon. Yeah, sorry, that goes to road maintenance too -- about $3 million/year compared to about $8 million/year from the bond ( https://www.eugene-or.gov/1086/Bond-Measures-to-Fix-Streets )

As for the state and federal gas taxes, not sure exactly where those go (except to the state and the feds), but not exactly sure how or in what form they come back to local communities. Grants maybe? And they did just build a $200 million interstate bridge over the Willamette.

Anyway, I can think of lots of reasons we should tax gasoline. If you believe at all in taxing things we want people to use less of (tobacco, etc) ... it makes sense. If you don't, or you don't think it matters that we try to curtail how much gas we use, it might not make sense.

I'd venture the gas tax should probably be a fair bit higher, but I'm veering off topic here.
