Disadvantages

Pedestrian overpasses over highways or railroads are expensive, especially when elevators or long ramps for wheelchair users are required. Without elevators or ramps, people with mobility handicaps will not be able to use the structure. People may prefer to walk across a busy road rather than climb a bridge, and this may be attributed to being in a hurry, perceiving the safety and security of the footbridge to be low, or simply because of feeling tiredness when climbing the stairs. It is recommended that overpasses should only be used where the number of users justify the costs. The operational concept of the footbridge is based on the notion that pedestrians need to walk a longer distance and exert more physical effort so that the traffic flow is not interrupted. This is not in line with the sustainability goals of the transport system promoting active travel such as walking and cycling. A change of policy to increase safety and

could involve transferring that effort of crossing the road to drivers who will need to wait longer so pedestrians can cross the road safely at street level. Narrow, enclosed structures can result in perceptions of low personal security among users. Wider structures and good lighting can help reduce this.
