In the sweltering July heat of Tianjin, construction crews are working diligently to advance the project schedule. At the site of the Beichen District Northern New Area Grand Bridge, a key segment of the third section of the Beijing-Tianjin-Tanggu Expressway (Tianjin section) expansion and upgrade project, workers are persisting through high temperatures to methodically progress the superstructure construction of the bridge.
As a pioneering project in China's expressway network and one of the earliest highways opened in the Beijing-Tianjin-Hebei region, the Beijing-Tianjin-Tanggu Expressway is often called the "Golden Corridor." It has long been instrumental in driving industrial agglomeration along its route and empowering urban development. With the deepening integration of the Beijing-Tianjin-Hebei region, regional traffic volume has surged, and the original road conditions can no longer adequately meet the demands for convenient public travel and the efficient flow of regional resources.
This expansion and upgrade project aims to comprehensively improve road conditions, address transportation bottlenecks, and enhance the travel experience for the public. The project has now entered a critical construction phase.
Current Construction Progress
"The subgrade construction for the current third section is now fully complete, shifting the project's focus entirely to superstructure construction," explained project manager Li Siming. To minimize the impact on public travel, the project is employing a construction plan that keeps one side of the road closed while the other remains open to traffic. Standardized traffic management measures, including the installation of steel trestle bridges, safety barriers, and comprehensive traffic signage, are being implemented to balance construction safety with maintaining normal road operations.
Navigating Seasonal Challenges
Midsummer brings frequent extreme weather, including intense heat and heavy rainfall, presenting a dual challenge for outdoor bridge construction. In response, the project team has prioritized flood prevention safety, focusing on the specific demands of construction during the flood season and building a comprehensive safety defense line.
Li Siming noted that before the flood season began, the project department organized emergency flood response drills involving all participating construction units. These practical training sessions ensured all construction personnel were proficient in necessary emergency skills.
"Since entering the flood season, we have conducted regular, unscheduled safety inspections on large equipment like cranes and bridge erection machines to eliminate potential accidents at the source," Li Siming said. "Simultaneously, we strictly enforce a 24-hour duty system, conducting continuous patrols of all risk points at the construction site to ensure any potential dangers or hidden risks are identified and addressed early." Following the lifting of meteorological warnings, the project department conducts thorough, systematic safety inspections to verify all flood prevention measures are properly implemented.
Ensuring Worker Safety and Well-being
Alongside flood prevention efforts, comprehensive heatstroke prevention measures are in place. At the construction site, specially erected rest shelters provide shade, and a regular supply of heat-relief items such as Huoxiang Zhengqi water, mung bean soup, and drinking water is maintained, offering ample convenience for workers during breaks.
"Considering the summer characteristics of high temperatures and frequent rain, we have implemented a staggered work schedule," explained site safety officer Li Shuaiwei. "We actively avoid the hottest periods of the day. Through this refined management approach, we are fully committed to safeguarding the physical health and safety of all construction personnel."
Project Scope and Impact
The Beijing-Tianjin-Tanggu Expressway (Tianjin section) expansion project starts at the border between Tianjin and Hebei Province and extends to the Tanggu Toll Station, covering a total length of approximately 96.8 kilometers. The project involves widening the existing road on both sides, upgrading it from a dual four-lane to a dual eight-lane configuration, with a design speed of 120 kilometers per hour along the entire route.
The third section, located within Beichen District, spans nearly 14 kilometers and is a crucial segment of this expansion project. Officials from the Municipal Transportation Commission stated that this upgrade will significantly enhance the traffic capacity for towns along the route. It will better serve the Beijing-Tianjin-Hebei region, promoting more accessible transportation, efficient resource flow, and coordinated industrial development among the three areas.
