In real estate and industrial construction, infrastructure comes first and value follows. Since Hai Duong merged into Hai Phong on 1 July 2025, the former province's road network is part of one system linked to the seaport, Cat Bi airport and coastal economic zones.
Main corridors
| Corridor | Role |
|---|---|
| National Highway 5 | Hanoi – Hai Duong – Hai Phong spine with many industrial parks |
| Hanoi – Hai Phong expressway | Faster freight to the port across the south of the area |
| Highway 18 | Links Chi Linh with Bac Ninh and Quang Ninh |
| Highways 37 and 38 | Cross links to neighbouring provinces |
| Hanoi – Hai Phong railway | Freight and passengers alongside Highway 5 |
Impact on investment
Distance to expressway junctions and the port drives logistics costs for factories and warehouses. For residential land, distinguish roads that are funded or under construction from lines that only exist on planning maps. For contractors, site access determines how fast materials and steel arrive.
Internal infrastructure
Site levelling, separate storm and wastewater drainage, water, power, lighting and pavements decide the quality of a residential area. PQT plans and builds this work; see PQT infrastructure projects or contact PQT.
