Hypothetically, if I built a system tomorrow that recommended which roads and bridges were most worth spending on (because they actually enable economic activity but are in poor condition, so not vacation bridges), is there enough leeway in this bill to actually advise the spending? I don't have the skills to do that, much less by tomorrow, but I'm wondering how set in stone the list of actual bridges to work on is.
