Provincial Road 158 is a backbone route running from A Mu Sung and A Lu communes to the Y Ty highland tourist commune of the old Bat Xat district, Lao Cai province.

In addition to the renovation of Provincial Road 158, leading to this mountainous tourist commune, there is also a project to upgrade Ban Xeo - Den Sang - Y Ty road with a total length of 33.58 km, starting at Can Ty intersection, ending at the intersection with Trinh Tuong - Y Ty road.

Sharing with Lao Dong Newspaper reporter, Mr. Nguyen Van Tai - Chairman of the People's Committee of the new Y Ty Commune, Lao Cai Province said: "After merging with A Lu Commune, the local area has now become significantly larger. Although Y Ty is a border commune, it has a lot of potential to develop tourism in a cool climate with the typical culture of ethnic minorities.
The state's attention to investing in transport infrastructure is important when attracting tourists to explore, experience and help people travel more conveniently and safely".
According to Mr. Nguyen Van Tai, important traffic projects leading to Y Ty commune will be basically completed in 2025, at the latest by early 2026.
