The Ministry of Transport has just sent a document to relevant units regarding the adjustment to increase the operating speed of the expressway with 4 lanes for motor vehicles with a median strip (2 lanes in each direction).
Accordingly, the Ministry of Transport agreed to allow 8 sections of 4-lane limited expressways to operate at a maximum speed of 90km/h instead of 80km/h as currently for cars, passenger vans with up to 30 seats, and trucks up to 3.5 tons, including: Mai Son - National Highway 45, National Highway 45 - Nghi Son, Nghi Son - Dien Chau, Dien Chau - Bai Vot, Nha Trang - Cam Lam, Cam Lam - Vinh Hao, Vinh Hao - Phan Thiet, Lao Cai - Kim Thanh.
The Department of Construction Investment Management is responsible for directing project management boards and investors of expressway projects with a scale of 4 lanes with a median strip (also known as limited 4-lane expressways) to review routes under management or temporary operation, check technical factors to ensure that they meet the operating speed of 90km/h as prescribed; Adjust the operating speed in the route traffic organization plan, and submit it to the Vietnam Road Administration for approval.
The process of adjusting speed signs must ensure the necessary technical solutions for synchronous and safe operation.
For the 15km Cao Bo - Mai Son expressway, because the route has 4 bridges without continuous hard dividers, not ensuring the required acceleration section length, the operating speed will not be adjusted to increase until the route is upgraded and expanded to meet technical requirements.
Based on the traffic organization plan prepared and submitted for approval by investors and management units, the Vietnam Road Administration approves the traffic organization plan to adjust projects that are eligible to increase the operating speed. At the same time, it directs the Road Management Areas that are managing the operation of the expressways with investment phases to complete the necessary procedures to increase the operating speed to meet travel needs.

To effectively implement the Prime Minister's Official Dispatch No. 10/2024 on strengthening solutions to ensure traffic safety and order during the Lunar New Year and Spring Festival 2024, the Ministry of Transport requests agencies and units to direct investors and management and exploitation units to adjust the speed for expressways with investment phases that are eligible for completion before the Lunar New Year to contribute to reducing traffic congestion and better meet people's travel needs during the holidays.
"The Vietnam Expressway Administration and the Construction Investment Management Department perform the functions of a specialized construction agency under the Ministry of Transport for expressway construction investment projects that are being prepared or being invested in nationwide as assigned to ensure synchronization and unity in operation speed," the Ministry of Transport directed.
Previously, the Vietnam Road Administration had sent a document to the Ministry of Transport proposing to increase the operating speed of some expressways. Accordingly, recently, the expressway sections including My Thuan 2 Bridge and the access roads at both ends of the bridge; My Thuan - Can Tho; Trung Luong - My Thuan; Tuyen Quang - Phu Tho have been invested by the Ministry of Transport, the People's Committee of Tien Giang Province, and the People's Committee of Tuyen Quang Province with 4 motor vehicle lanes, with a hard median strip separating the two directions of traffic and allowing operation at a maximum speed of 90km/h. During the recent operation period, the work of ensuring order and traffic safety has been stable so far.
On that basis, the Vietnam Road Administration recommends that the Ministry of Transport direct and request investors who are building and managing expressways, and agencies managing investment-phased expressway sections to design with 4 motor vehicle lanes of similar scale, with a hard median separating the two directions of traffic, organize the installation and adjustment of signs for the maximum permitted speed of 90km/h and adjust signs to maintain a safe distance at this speed .
