National Highways 14B–14D Corridor

The National Highways 14B–14D corridor links Da Nang’s coastal logistics system with the mountainous interior and the Nam Giang international border crossing toward Laos.

Overview

Understand the asset as a connected system of infrastructure, operations and access.

The corridor combines distinct national highways rather than a single numbered road. National Highway 14D connects the Ho Chi Minh Road near Ben Giang with the Nam Giang border area. A 65.37 km upgrade project for Highway 14D began on 26 June 2026, with completion expected in 2028 according to the city portal. The existing road and the improvement works must be distinguished.

Key things to understand
