North–South Expressway West

The North–South Expressway West (Vietnamese: Đường cao tốc Bắc – Nam phía Tây) is a partially completed expressway in Vietnam that will form an inland parallel route to the North–South expressway. It will run from Đoan Hùng to Rạch Sỏi in the Mekong Delta, following a similar route to the historic Ho Chi Minh Highway. Between Hà Tĩnh and Da Nang, the narrowest part of Vietnam, it will be concurrent with the North–South Expressway.

History
The section Cao Lãnh - Lộ Tẻ opened in May 2018 and includes two major cable-stayed bridges, Cao Lãnh bridge over the Tiền River, and Vàm Cống bridge over the Hậu River. These bridges replaced ferry services, also carrying lanes for slower traffic.

The section Lộ Tẻ - Rạch Sỏi was completed in January 2021, however only as a 2x2 lane trunk road, pending future upgrade to full expressway standard. The section was constructed at a cost of VND 6,355 billion (US$270 million), partially financed by the Korean government through a development loan.
