Optimal design of modification of bridges into roadbeds is a technical problem that is often encountered in construction of expressways in mountainous area, and reasonable optimal change according to actual conditions of site will produce good effect. This paper analyzes the scheme of modifying one bridge into roadbed on Chognqing Qianjiang - Hubei Enshi Expressway Project, and demonstrates practicality, economy, environmental protection and reliability of the scheme of modifying the bridge into roadbed in accordance with topographic and geological conditions of site and requirements for discarded earthwork. The results of demonstration show that the scheme of optimal change of modifying bridges into roadbeds has better economic benefits and environmental protection values.
