In 2010, BS 5400 was superseded by the Structural
Eurocodes

for the design of new bridges. However, BS 5400 still serves as the foundation for assessment standards concerning existing highway and railway structures. Some of the prescriptive clauses from the old code have been reformulated to align with the principles of the Eurocodes and are presented as advisory material within British Standard Published Documents. These documents serve as non-contradictory complementary information (NCCI) to the Eurocodes, providing means of compliance with Eurocode requirements, often utilizing closed-form solutions familiar to engineers experienced in the application of BS5400.
