On April 28, 2020, the groundbreaking ceremony of Cua Luc 1 Bridge Project – The Project is in the general planning of Ha Long city which approved by the Prime Minister on intending to develop and expand urban space to collect attracting investment in industrial zones – has been taking place in Quang Ninh city.
Once again, Duafat is predestined to bridges, ports, rivers – sea. Previously, there were berth constructions with the scale of Bach Dang bridge, Hoang Van Thu bridge … Hoa Phat deep-water port, Hoa Phat Dung Quat iron and steel factory …
After completion, Cua Luc 1 bridge is expected to contribute to the socio-economic development momentum; minimize traffic flow through Bai Chay and Highway 18 through the inner city area of Ha Long city, ensuring the travel demand for people in the rainy season.
The starting point of the Project intersects the road linking Cai Lan industrial park through Viet Hung industrial park to Ha Long Van Don highway in Gieng Day area, Ha Long city. The endpoint of the Project intersects with National Road.279 at KM25 + 750 in Le Loi commune, Hoanh Bo district. The whole route length is 4,265.12m (of which: the main bridge is 290m long, the bridge leading to Ha Long is 126.1m long, the Hoanh Bo side is 469.52m long; the bridge over the planned canal km1 + 950 is 110.55m long and Km3 + 447 is 48m long; the leading road Ha Long bridge is 400.09m long, Hoanh Bo is 903.74m long; the road connecting NR. 279 is 1917.12m long).
Bridge scale: Constructing Cua Luc 1 bridge over Troi river with the scale of permanent bridges of reinforced concrete and pre-stressed reinforced concrete, the main span is in the form of concrete tube arches of the bridge deck running between; River level III, communication width BxH = (40.0×7.0) m; Design load HL93, pedestrian load 3×103– MPa, design frequency P = 1%; level-VII earthquake (according to scale MSK-64); Bridge width 33.1m, 06 lanes.
Path scale: Main urban streets; Design speed Vtk = 60km / h; calculated flood frequency P = 4%. Construction standards TCXDVN 104: 2007 and QCVN 07-4: 2016 / BXD; Scale cross section of road foundation from 30.5m to 35.5m, 6 lanes running.
Complete construction of work items: Intersection; Bridge and sewer constructions; Sidewalks, trees, electric lighting and fine art lighting; Traffic Safety.
