HÀ NỘI – The Directorate for Roads of Việt Nam (DRVN) has proposed the Ministry of Transport increase the maximum speed on 4-lane expressways to 90km per hour from 80km per hour.

Roads eligible to increase the maximum operating speed to 90km per hour include Mỹ Thuận Bridge 2, Mỹ Thuận-Cần Thơ, Trung Lương-Mỹ Thuận and Tuyên Quang-Phú Thọ.

Recently, DRVN has reported to the Ministry of Transport on the work of posting maximum speed limit signs on limited access highways with four motor vehicle lanes.

Since late December last year, there have been four sections of the four-lane limited access highway being permitted a maximum speed from 80km to 90km per hour, including Mỹ Thuận Bridge 2, Mỹ Thuận-Cần Thơ, Trung Lương-Mỹ Thuận and Tuyên Quang-Phú Thọ expressways, said DRVN.

According to reports from the Project Management Boards (PMUs) and the departments of transport managing the expressways, after a period of exploitation and monitoring, traffic is initially stable.

To ensure uniformity, DRVN proposed the Ministry of Transport allow the 4-lane limited access highways with a hard median divider to have maximum operating speed of 90km per hour.

The Ministry of Transport requested investors and PMUs to continue monitoring traffic organisation and safety on the route to promptly detect any problems and shortcomings so as to report to competent authorities to adjust the speed of operation and traffic organisation plans to ensure safe and smooth traffic.

PMUs, departments and investors of highways need to complete additional investments to enhance the work of ensuring traffic order and safety, including intelligent transportation systems (ITS) for the project of managing, operating and maintaining the transportation infrastructure.

Previously, DRVN also proposed the Ministry of Transport increase the maximum speed from 80km to 90km per hour for vehicles up to 30 passengers and trucks up to 3.5 tonnes on nine 4-lane expressways including Lào Cai-Kim Thành expressway, Cao Bồ-Mai Sơn, Mai Sơn-Highway 45, Nghi Sơn-Highway 45, Nghi Sơn-Diễn Châu, Nha Trang-Cam Lâm, Cam Lâm-Vĩnh Hảo, Vĩnh Hảo-Phan Thiết, and Mỹ Thuận-Cần Thơ.
