| Aspects | Greenfield Roads | Regular Road Upgrades |
|---|---|---|
| Initial Cost | High (₹20–40 crore/km for expressways) | Lower (₹5–10 crore/km for upgradation) |
| Construction Time | 4–8 years due to land acquisition, clearances | 1–3 years for widening and strengthening |
| Funding Model | Hybrid Annuity Model (HAM), BOT, PPP | Budgetary allocations, EPC contracts |
| Maintenance Cost | Lower due to new build quality | Higher due to wear and congestion |
| Parameters | Greenfield Roads | Regular Roads |
|---|---|---|
