The Ministry of Transport has agreed to increase the maximum speed of 8 expressways to 90km/h
The Ministry of Transport has just sent a document to the relevant units about adjusting the maximum speed for the operation of divided investment expressways designed with 4 motor lanes with a median strip (2 lanes in each direction).
8 restricted 4-lane expressway sections can be operated at a maximum speed of 90km/h instead of the current 80km/h for cars, passenger buses up to 30 seats, and trucks up to 3.5 tons, which is agreed by the Ministry of Transport. These expressway sections are: Mai Son – QL45, QL45 – 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 Management Board of Investment and Construction is responsible for directing project management boards and investors of divided investment expressway projects with a scale of 4 motor lanes that have a median strip (also known as restricted 4-lane expressways) to review the managed and temporarily operated road sections, check the technical factors to ensure that they meet the regulated operating speed of 90km/h, adjust the operating speed in the traffic organization plan, and submit it for approval by the Vietnam Road Administration.
The adjustment of the speed limit signs must ensure the necessary technical solutions to operate synchronously and safely.
Regarding the 15km Cao Bo – Mai Son expressway section, as it has 4 bridges without a continuous hard median strip that meets the required length of the acceleration zone, the increase in the operating speed has not been adjusted for now, until the road section is upgraded and expanded to meet the technical requirements.
Based on the traffic organization plan established and submitted for approval by the investors and management units, the Vietnam Road Administration approves the adjustment of the operating speed for projects that meet the conditions. At the same time, it instructs the road management agencies currently managing and operating the divided investment expressway sections to complete the necessary procedures to increase the operating speed to meet the travel demand.
The adjustment of the speed limit for expressway sections that meet the conditions for completion before the Lunar New Year 2024
In order to effectively implement Official Letter No. 10/CĐ-TTg dated January 29, 2024 of the Prime Minister on strengthening measures to ensure traffic order and safety during the Lunar New Year and Spring Festival 2024, the Ministry of Transport requires agencies and units to instruct investors and management units to adjust the operating speed for expressway sections that meet the conditions for completion before the Lunar New Year 2024 to contribute to reducing traffic congestion and better meeting the travel demand of the people during the holidays.
The Vietnam Expressway Administration and the Management Board of Investment and Construction perform the functions of the specialized agencies for construction under the Ministry of Transport for investment projects that are being prepared or being implemented nationwide to ensure consistency and uniformity in the operating speed.
Prior to that, in a proposal to the Ministry of Transport, the Vietnam Road Administration stated that recently, several expressway sections including My Thuan 2 Bridge and the connecting roads on both ends; 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 lanes and a hard median strip dividing the two directions of traffic, allowing operation at a maximum speed of 90km/h. During the recent period of operation, the work of maintaining traffic order and safety has been stable.
From here, the Vietnam Road Administration recommends that the Ministry of Transport directs and requires the investors who are constructing and managing the expressways, as well as the management agencies of the divided investment expressway sections designed with 4 motor lanes and a hard median strip, to organize and adjust the maximum speed limit to 90km/h and adjust the distance warning signs for this speed.
