What is BS EN 1995-2 - Timber bridge design about?  
Timber is a natural insulator and can help reduce energy needs when it is used in windows, doors, and floors. BS EN 1995-2 discusses the design of timber structures bridges.
BS EN 1995-2 is the second part of the multi-series that applies to the design of buildings and civil engineering works in timber (solid timber, sawn, planed or in pole form, glued laminated timber, or wood-based structural products e.g. LVL) or wood-based panels jointed together with adhesives or mechanical fasteners. It complies with the principles and requirements for the safety and serviceability of structures, and the basis of design and verification that are given in EN 1990:2002.
BS EN 1995-2 is only concerned with requirements for mechanical resistance, serviceability, durability, and fire resistance of timber structures.
Note: Other requirements, e.g., concerning thermal or sound insulation, are not considered.
BS EN 1995-2 covers the following subjects:
- Basis of design
- Material properties
- Durability
- Basis of structural analysis
- Ultimate limit states
- Serviceability limit states connections
- Structural detailing and control
Who is BS EN 1995-2 - Timber bridge design for? 
BS EN 1995-2 on timber bridge design is useful for: 
- Relevant government / municipal / roadway authorities
- Designers of timber structures
- Designers of bridges
- Project managers
- Civil engineers/ Contractors/ Architects 
- Manufacturers and suppliers of wood-based products
- Real estate developers
- The construction industry
Why should you use BS EN 1995-2 - Timber bridge design?  
A timber frame allows more space for insulation than a brick structure, and the wood itself also has naturally thermally insulating properties.
BS EN 1995-2 provides common structural design rules for everyday use for the design of whole structures and component products of both a traditional and innovative nature.
BS EN 1995-2 describes the principles and requirements for safety, serviceability, and durability of timber bridges. It is based on the limit state concept used in conjunction with a partial factor method.
For the design of new structures, BS EN 1995-2 is intended to be used, for direct application, together with EN 1995-1-1 and EN1990:2002 and relevant Parts of EN 1991.
BS EN 1995-2 gives alternative procedures, values, and recommendations with notes indicating where national choices may have to be made.
BS EN 1995-2 gives general design rules for the structural parts of bridges, i.e. structural members of importance for the reliability of the whole bridge or major parts of it, made of timber or other wood-based materials, either singly or compositely with concrete, steel or other materials. 
BS EN 1995-2 guidelines help you with the efficient structural design and ensure the safety, serviceability, and durability of timber bridges.
Second Generation of EN Eurocode Standards
The second generation of EN Eurocode standards is expected to be published between 2023 and 2026. These documents are being published as soon as they are available, to enable users to prepare for the transition from the first generation to second generation of Eurocodes. As set out in the National foreword of the BS EN second generation Eurocodes, UK adoptions of the first generation of Eurocodes will be withdrawn by BSI on 30 March 2028. That means there is a period of coexistence between 2023 and 2028 during which both first and second generation Eurocodes are available.
Until 30 March 2028, the first generation documents should be considered as the applicable standards for buildings and civil engineering works constructed in the UK unless otherwise specified by the relevant authority or in the specification for a particular project. While the use of provisions in second generation Eurocodes in conjunction with first generation Eurocodes is not precluded, it should be undertaken with care and should only be done when users are satisfied that it will not result in a lower level of reliability than the minimum level set in the first generation Eurocodes and associated UK National Annexes.
