Climate change is one of the most challenging problems for the world, which leads researchers to study on the decrease of its impact to the environment at several disciplines. One of the most adverse effects on environment can be observed in transportation area. Hence, in this paper, the impact of bridge maintenance on the environment is inquired in the bridge maintenance prioritization perspective. The aim of this paper is to rank the bridge maintenance projects using type-2 neutrosophic number (T2NN) based fuzzy WASPAS (Weighted Aggregated Sum Product Assessment) and TOPSIS (Technique For Order Preference By Similarity To An Ideal Solution) to test five alternative bridges, where a critical environmental criterion is introduced in this model, which addresses to additional $C{O}_2$ emission because of truck detours in the event of a bridge closures. The applicability of the proposed model is demonstrated in a case study in Turkey. The evaluation findings show that the ranking results are robust and the $C{O}_2$ emission criterion is found to be the dominant criterion in the multi-criteria decision-making model proposed in this paper.

气候变化是世界上最具挑战性的问题之一，这导致研究人员在多个学科研究减少其对环境的影响。在运输区域可以观察到对环境最不利的影响之一。因此，在本文中，桥梁维护对环境的影响从桥梁维护优先级的角度进行了探讨。本文的目的是使用基于 2 型中智数 (T2NN) 的模糊 WASPAS（加权聚合和乘积评估）和 TOPSIS（通过与理想解决方案相似的顺序偏好技术）对桥梁维护项目进行排名，以测试五个替代桥梁，在该模型中引入了一个关键的环境标准，该标准针对额外的$C{○}_2$在桥梁关闭的情况下，由于卡车绕道而排放。土耳其的一个案例研究证明了该模型的适用性。评估结果表明，排名结果稳健，$C{○}_2$在本文提出的多准则决策模型中，发现排放准则是主导准则。
