Much of the beltway was built completely with local funds and expressway to freeway upgrades have continued to be built without state or federal money (except for the I-515 interchange upgrade). A tax measure voted on by the County residents increased funding for the beltway. As a result, it was expected to be fully upgraded to a freeway by 2013, rather than the previous goal of 2025. However, at present it appears that this target date has slipped back at least a few years.
