Every corridor has advocates. The question is never whether a road needs work — it is which of forty roads that all need work gets funded first, and on what grounds.
Prioritisation is a scoring exercise. Projects are rated against criteria agreed in advance: crash history, congestion, freight importance, connection to transit, cost per benefit, and whether the corridor serves communities that have historically been under-served. The scores are public, and so is the weighting.
| Criterion | What it measures | Common objection |
|---|---|---|
| Safety | Crashes per mile, weighted by severity | Rewards roads that are already dangerous rather than preventing danger |
| Congestion | Delay against free-flow travel time | Peak-hour delay is not the same as a road being broken |
| Freight | Truck volumes and port access | Economically strong, locally unpopular |
| Equity | Access for communities with fewer alternatives | Hard to score without proxies that distort |
| Readiness | Whether design and right-of-way are in hand | Quietly decisive: a ready project beats a better one |
Readiness is the criterion outsiders miss. A project with completed design and acquired right-of-way can absorb money that appears unexpectedly at the end of a fiscal year. A better project that is not ready cannot. This is why some corridors seem to jump the queue.
The default intervention — add a lane — is also the one with the weakest long-run record. Induced demand is well documented: new capacity fills, and within a few years travel times return to roughly where they were, now with more vehicles. Signal timing, access management, turn lanes and transit priority are cheaper and often buy more.

Yes, and it happens. Cost estimates rise, environmental review turns up something, or a local government withdraws its share. Funded means scheduled, not guaranteed.
Usually because earlier studies recommended something nobody was willing to fund. The study is cheap; the recommendation is not.
Rarely on its own, often in aggregate and early. Comment during a plan update is worth more than comment during construction.
