Footway build-outs

A build-out is a section of kerb/footway extended out into the carriageway on one side only to narrow the road. They can reduce crossing distances and improve visibility for pedestrians. If the space is available, a gap can be left between the pavement and the build out to form a cycle bypass.

It is particularly beneficial near parked cars (see sheltered parking) but can also be used as part of a chicane system (see priority chicanes and priority narrowing).

Build-outs can be difficult to achieve where there are many private driveways restricting their positioning.

Indicative costs

A build-out is normally furnished with bollards and dropped kerbs/tactile facility and usually costs approximately £12,000.
