　　The Dahuanjiang Bridge is a two-T rigid frame bridge, constructed by Guizhou Road & Bridge Group under the Heli T1 bid section, and is one of the control projects of the Heli Expressway. The left span of the bridge has a total length of 742.6 meters, and the right span has a total length of 662.6 meters, with the highest pier column at 63 meters. The main bridge is a continuous rigid frame bridge consisting of one main span of 135 meters and two side spans of 73 meters, with tunnels over 2,000 meters long connected at both ends of the approach bridge.

　　To ensure the orderly construction of the Dahuanjiang Bridge, in the face of difficulties such as a tight schedule, heavy tasks, and high risks, the builders braved hardships and rose to the challenges. They organized and established a Party member vanguard team and a youth commando team to carry out a "dual offensive" in technology and management for the bridge construction, jointly solving technical problems at the construction site, investigating and rectifying safety and quality hazards, and continuously advancing standardized construction, ensuring controllable safety and quality and orderly progress of the bridge construction, and safely and smoothly achieving double-width completion of the Dahuanjiang Bridge with guaranteed quality and quantity.

The Heli T1 bid section will continue to maintain the spirit of "working hard and fast, and truly doing solid work," completing the next node target task with guaranteed quality and quantity and going all out, helping the Heli Expressway write a new chapter.
