Introduction to bridges and connected networks
New or upgraded bridges can improve accessibility and connectivity for people walking, wheeling and cycling.
The use of bridges should generally be avoided, as level changes and increased distances can make an active travel route less comfortable and convenient. However, new bridges can be essential in a connected network of good, safe routes. They may be needed to overcome major barriers on a desire line that cannot be crossed safely in another way.
When to use a bridge
Bridges should have an attractive design and can become a new landmark. Bridges for walking, wheeling and cycling only can help to create active places. They significantly improve the accessibility and connectivity of new development, if other ways to connect are not possible. For instance, active travel bridges over rivers connect to wider countryside and natural habitats, or to existing towns and other destinations.
Inclusive bridges
Bridges can be difficult for disabled people to use. Good practice standards on stairs, ramps, lifts and handrails can be found in Inclusive Mobility and need to be followed. Gradients should not exceed 1 in 20. Level landings should be provided every 500mm that the route rises to give people an opportunity to rest. Where possible accessible seating should be provided on landings.
Bridges should be as wide, short, as direct as possible, and have good lighting to improve the perception of security and makes routes more legible.
Minimum widths and parapet heights for bridges are set out in Cycle Infrastructure Design (LTN 1/20).
