Wenzhou, Zhejiang: Ouhai Avenue Tunnel Lighting Revitalization Completed

Recently, the comprehensive revitalization project for the lighting systems within the main tunnels of Ouhai Avenue in Wenzhou, Zhejiang Province, was successfully completed. As a major transportation artery connecting the eastern and western sectors of the city, the lighting infrastructure within the Ouhai Avenue main tunnels-originally refurbished and commissioned in 2016-had gradually begun to suffer from issues such as aging components, light decay, and uneven illumination. These deficiencies not only diminished visual comfort for drivers but also posed adverse risks to traffic safety.

Wenzhou, Zhejiang: Ouhai Avenue Tunnel Lighting Revitalization Completed

To minimize the impact of this revitalization project on main-road traffic, the municipal streetlamp maintenance team in Wenzhou adopted a “short-duration, streamlined, and rapid” night-time construction model starting April 23. Working in close coordination with traffic management and expressway maintenance departments, the team flexibly scheduled lane closures to facilitate construction. Following 10 nights of intensive work-involving a total deployment of 190 personnel-the team efficiently completed the full replacement of over 2,000 light fixtures.

This lighting revitalization project represents several significant breakthroughs in terms of both technical innovation and operational detail compared to previous efforts. Regarding construction methodology, scissor lifts were introduced for the first time; their enhanced maneuverability significantly boosted operational efficiency within the tunnels confined and elongated spaces. In terms of lighting quality, the newly installed fixtures feature a standardized color temperature of 4000K, producing a more neutral and softer light that effectively mitigates visual disparities experienced when transitioning between the bright outdoor environment and the tunnel interior. From a technical infrastructure standpoint, the project involved replacing older-generation LED streetlamps (rated at 120 lm/W) with high-efficiency LED models (rated at 160 lm/W). This upgrade not only ensured a 25% increase in illumination levels but also achieved a 21.5% reduction in energy consumption. Furthermore, the configuration of both “enhanced lighting” and “basic lighting” systems was optimized and tailored to the specific functional requirements of different tunnel sections. This strategic adjustment effectively alleviates the “black hole effect”-the sudden sensation of darkness experienced by vehicles entering a tunnel-thereby ensuring a smoother and safer transition for passing traffic.

As a mountainous and hilly village, Youling Village previously lacked lighting facilities on its main roads and in the residential areas. Every night, the roads were pitch black, causing significant inconvenience for villagers traveling at night, picking up and dropping off children, and returning from working in the fields, posing significant safety hazards. Improving lighting facilities was a pressing need for the villagers. During routine door-to-door visits, the Shaoyang Municipal Party Committee Policy Research Office and the Shaoyang Telecom Company’s village-based work team accurately identified this urgent need of the villagers and, adhering to the working principle of “doing practical things for the people,” quickly prioritized the Youling Village main road lighting project as a key livelihood project.

To ensure the streetlight project was tailored to the village’s specific circumstances and benefited more villagers, the village-based work team, in conjunction with the village’s Party committee and village committee, conducted multiple on-site surveys. Taking into account the main roads and the distribution of villagers’ residences, they scientifically planned the streetlight placement, balancing practicality and coverage. Simultaneously, the two organizations invested 200,000 yuan in assistance funds, connected with a professional construction team, and strictly controlled construction quality and progress. After more than ten days of intensive construction, dozens of solar streetlights were installed, tested, and officially put into use. From the main road at the village entrance to the core residential area, bright streetlights lined the street, completely transforming the old appearance of nighttime travel in Youling Village.

As night fell, the newly installed streetlights lit up one by one, their soft light illuminating the village streets and alleys. Villagers came out of their homes to stroll, chat, and relax, their laughter echoing along the village roads. “Before, we had to use flashlights when going out at night, afraid of falling. Now that the streetlights are on, it’s much more convenient to go out, and we feel safer letting the children go home from school at night!” The villagers of Youling Village couldn’t hide their joy when talking about the new streetlights, praising them repeatedly. Streetlights are not only lighting facilities in the countryside, but also “heart-connecting lights” that link the relationship between officials and the masses, continuously enhancing the villagers’ sense of happiness and fulfillment right at their doorsteps.
