DESIGN MANUALBRIEF DUTCH

FOR BICYCLE AND PEDESTRIANBRIDGES

BRIEF DUTCH DESIGN MANUAL FOR BICYCLE AND PEDESTRIAN BRIDGES

As one of the Netherland’s main bridge design offices, ipv Delft has focused on designing bicycle and pedestrian bridges for two decades. The company has used their extensive experience in bridge design to write this publication. This design manual focuses on the fundamentals of bridge design, answering practical questions regardign issues such as bridge width and slopes. It also lists the things that should be taken into account before starting on the actual design and it offers insight in the Dutch regulations regarding loads and collision forces. General advice on cost re-duction is also included and several of the company’s projects are shown to illustrate the theoretical contents. The Brief Dutch Design Manual for Bicycle and Pedestrian Bridges therefore is a vital source of both practical information and bridge design inspiration.

This publication is an English summary of the Dutch Design Manual for Bicycle and Pedestrian Bridges, which was published by CROW in 2014 and written by ipv Delft.

ConclusionsTo develop bridges that satify all involved and their requirements:

• Analyse requirements thouroughly• Involve all from the start• Create understanding & openess• Start with the crossings• Seek - Modularity -ContextualBenefits - Filters - Integration & Optimization

- Be open to practical custom new solutions. - Bridges are almost never standard solutions.- A custom solution can be best and cheapest.
