September 20，It took three years to buildGLine 215 Mazongshan-Qiaowan First-Class Highway Officially Opened to Traffic。After opening to traffic, the regional road network structure will be further improved.，Improve local transport capacity，Effectively improve the travel conditions of the masses。

Maqiao Highway is an important national highway from Mazong Mountain in Subei County of Jiuquan City to Qiaowan Old Town in Guazhou County of Jiuquan City.，In 2018, the secondary road was completed and opened to traffic.。Monitoring data show，More than 15000 large vehicles pass through every day.，The traffic pressure is high，Accidents occur frequently。After the completion of the first-class road of Maqiao Highway,，The road is open to double traffic，Help ease traffic pressure，Greatly reduce the accident rate。

At“The Belt and Road”Initiatives and“A transportation power”Under the background of the construction era，In recent years，Gansu Provincial Highway Traffic Construction Group has created one.“Highway+Lu Yan”The road to innovation.。First adopted in Gansu ProvinceEBOPattern（Entrust—Construction—Operate）The implementation of the integration of transportation and tourism projects.——Maqiao Highway Project came into being.。

GLine 215 Mazongshan to Qiaowan Highway is the only one in Gansu Province.G7 Beijing-Xinjiang Expressway andG30 connecting line from Lianyungang to Huoerguosi Expressway，The highway uses the existing secondary road as one.，Build a new one，It is constructed according to the technical standard of two-way four-lane first-class road.，Yes“Two to one”A highway engineering project。The alignment starts atG7 North Exit of Mazongshan Interchange, Subei County, Jiuquan City, Beijing-Xinjiang Expressway，It passes through Mazong Mountain、Sound Concave Gorge、Cave Ditch，The terminal point is located on the north side of Qiaowan Old Town, Guazhou County, Jiuquan City.，And GLine 312 is connected in sequence，Total route length 157.24 kilometers，Design speed 80 km/Hour。

Maqiao undertaken by the Fifth Company of CCCC First Highway Engineering Co., Ltd.MQTotal length of project route of Bid 2:56.29 kilometers，Including roadbed、Road surface、Traffic safety facilities、Greening and other construction tasks。The project is located in the hinterland of the Gobi Desert in the western section of the Hexi Corridor in Gansu Province.，Saline soil is widely distributed.，Water resources are seriously scarce，High alkali content in groundwater，Curing of cement stabilized materials is very difficult。The project adopts reverse osmosis water purification desalination purification equipment.，A new type of vibration stirring、Millimeter scaleGPSPavement of wide width and large thickness of water stabilized base、One-step forming technology for excavation of shallow dish-shaped side ditch foundation pit，For the project“Quality Engineering”The establishment of demonstration has laid a solid foundation.。

GThe completion of the highway from Mazongshan to Qiaowan on Line 215 initiated the history of highway construction in Gansu Province.“Two firsts”：The first innovative adoption“Entrust—Construction—Operate”YesEBOPattern，It is the first time to implement the integration of communication and tourism in a real sense.。The Gobi landscape along the Maqiao Highway、Site style and features、Wetland landscape、Organic series connection of oasis style and feature，Deep integration into the Great Dunhuang Cultural Tourism Economic Circle，Create and highlight regional culture、History and culture、Tourist Silk Road Corridor with Gobi Style，Provide convenient traffic guarantee for regional economic development。
