An extensive laboratory campaign was carried out to characterise brickwork and backfill material in masonry arch bridges. The framework presented in this research could be easily extended to analyze other large masonry arch bridges to better characterize their response to seismic hazards while providing useful information for transportation management authorities. This guidance provides guidelines on good practice for the appraisal, maintenance, repair and strengthening of masonry arch bridges, as well as advice on issues such as inspection, investigation and monitoring, bridge management, conservation, health and safety and environmental issues.

It was later replaced by a new steel truss bridge when the railroad was realigned due to construction of the conemaugh river dam.
To assure the stability of the masonry arch bridges, a model based on equilibrium equations and compatibility conditions is first developed
Next, the material properties are added to determine the formation of the hinges. Results from this experimental campaign can be used to develop and validate computational models for aging masonry arch bridges. In 2006, ciria c656 was published This new guide aims to update sections from the earlier publication
It presents good practice on the assessment of masonry arch bridges, taking on board findings from recent research.
