One of best suggested method to design highway bridges is by using LFRD approach. Load and Resistance Factor Design (LRFD) methodology or method is implemented based on strength analysis of concrete building, particularly for design of highway building.
AISC Steel Construction Manual (SCM) states that the use of LFRD approach can lead us to determine resistance and safety factor of such structures more accurately, consistently, efficiently and efficiently. Though, we can use Allowable Stress Design (ASD) methodologies, but it only combines two safety factors into a single factor of safety.
If you are new to LFRD approach for designing highway bridges, it is highly recommended to learn step by step design by reading Design of Highway Bridges: LRFD Approach book, written by Richard M. Barker and Jay A. Puckett. The authors include al theories and applications to get better design of highway bridges. Numerical analysis methods and techniques are also provided to cover structural analysis and approaches for all highway bridge designs in real world applications.
Design of Highway Bridges: LRFD Approach book includes solving worked problems that are used to design, select bridges type based on technical and aesthetic issues and also to analyze axle and lane loads on steel highway bridges and other concrete building. Design of Highway Bridges: LRFD Approach book can be considered as best reference for senior engineering students and practical engineers to learn fundamental concepts and theories of LFRD methods and knowledge of bridge design.

First of all helow
how doing well
So I am very happy that I connected with your site,
and this ahuge help for me and this will be helpfull for my knowledge,because I am acivil engineer and this information will improve my civil part so I really appriciate your help.
So I am hopeful to send me more this kind of worthy information.
best wishes
