Bridges are critical links within the highway infrastructure system; hence, they must continuously operate with minimal interruption to allow for the flow of people and freight. The objectives of the special issue are to increase the body of knowledge on engineering and management issues related to bridge structures. Specifically, it aims at bringing up to date the latest bridge research results, technical information, and practice on planning, design, construction, maintenance, replacement, management, security, and safety of highway and railroad bridges. Potential topics include, but are not limited to:

• Field monitoring and testing methods
• Innovative methods for infrastructure construction
• High-performance and high-strength materials
• Bridge design and construction
• Rating, rehabilitation, repair, and replacement of existing structures
• Load and resistance factor design
• Bridge serviceability issues
• Bridge management systems
• Aesthetics considerations
• Design codes, specifications, and standards
