HA TINH (VNS) — Overloaded trucks and hot weather are being blamed for damage to part of National Highway 1 between Vinh City and Ha Tinh Province that opened four months ago.
The construction to upgrade and expand the 35km section of National Highway No1 started in September, 2012 and completed in January, 2014 with investment of nearly VND2.5 trillion (US$ 119 million)
According to the project investor, the Civil Engineering Construction Corporation No4 (CIENCO 4), the project was completed nine months ahead of schedule, helping to save nearly VND500 billion ($23 million).
Director General of CIENCO 4, Le Ngoc Hoa, said depressions had appeared on the road.
He said that harsh weather and overloaded trucks had damaged the road.
Head of CIENCO No4's department for project management, Hoang Van Son, said that there were 21 rock mining sites along the route, resulting in a high number of trucks along the road.
The trucks were often overloaded with stone or soil, he said.
Director General Hoa said the corporation would install weigh bridges to control vehicles from next month.
He said they were also fixing the damage to the road and taking measures to curb the impacts of hot weather on the road surface by watering it on hot days and stopping trucks from using affected stretches.
According to the Transport Ministry, wheel marks are found on most routes with high volumes of traffic, including National Highway No1, National Highway No5 and Ha Noi's Ring Road No2, that threaten road safety.
Experts said the increase of overloaded trucks and poor quality road design and construction were the reason for the problem. — VNS
