Introduction of Luzhou Longtou Weir Bridge (under construction)?

Luzhou Longtouzhang Bridge and its connecting line project are located between Tuojiang Second Bridge and Tuojiang Third Bridge, starting from Danxia Road in Jiangyang District, passing through Jiangyang Central City, passing through Longtouzhang District in the form of a tunnel, then passing through Tuojiang River and ending at Nanguang Road in Longmatan District. The total length of the road is about 2.604km, and the road is planned as a first-class urban trunk road, with a design speed of 50km/h for the main line, 30km/h for the ramp, a standard road width of 28-32m and six lanes in both directions. The main line includes 645m bibcock bridge, tunnel 1 129m (double tunnel layout, single tunnel with two lanes), 780m interchange ramp tunnel (two lanes) and 280m interchange ramp bridge (two-way four lanes).

project plan

On June 30th, 20 12, the Housing and Construction Bureau of Luzhou City published six sets of design schemes for the leading barrier bridge on websites such as Luzhou Quansou for public voting. Among the six schemes, the "Longxiang Tuojiang" scheme is favored by the public for its simple and gorgeous appearance, and has won more than 50% of netizens' votes. According to the preliminary design scheme, the tunnel of this project will pass through Diaoyutai Community, Amethyst Xiyuan and other residential communities.

Bridge action

"To solve the internal traffic of the north-south group, we must first solve the bottleneck problem of the north-south trunk line traffic." The staff of the Municipal Housing and Construction Bureau said that with the completion and use of key projects such as Southwest Trade City and Luzhou Passenger Transport Center, key projects such as Luzhou Grand Theatre, Luzhou Olympic Sports Park, Luzhou high-speed railway station and Luzhou University City will be started one after another, and Chengbei New District will become a new downtown area of Luzhou integrating financial and trade, transportation and logistics, education and sports, office and residence.

However, because our city is surrounded by two rivers and limited by natural mountains, all the river-crossing groups must rely on the river-crossing bridge for traffic contact, and the river-crossing bridge plays an important role in the traffic system of our city. But up to now, there are only five river-crossing bridges (Yangtze River Bridge, Guojiao Bridge, Tuojiang No.1, No.2 and bridge three) in the main urban area of our city, and the number of cars in our city has exceeded 400,000. The traffic capacity provided by the river-crossing bridge cannot meet the demand of urban north-south traffic connection.
