A pedestrian underpass is a passage that allows pedestrians to cross beneath a road, railway or other obstacle without entering the traffic route above.

They separate pedestrians from motor vehicles, trains or other traffic, reducing direct conflicts at busy or high-speed crossings.

Not exactly. A pedestrian underpass is specifically intended to allow pedestrians to pass beneath an obstacle, while a tunnel can carry roads, railways, pedestrians or other forms of transport.

No. An underpass passes beneath the obstacle, while an overpass or footbridge carries pedestrians above it. Both provide grade-separated crossings.

This depends on the signs and design of the facility. Some underpasses are shared with cyclists, while pedestrian-only underpasses may require cyclists to dismount.

Yes. Some underpasses contain separate or shared pedestrian and cycle facilities so both categories can cross safely away from motor traffic.

No when the passage is specifically reserved for pedestrians. Maintenance or emergency access may be permitted in exceptional circumstances.

Yes, when suitably designed. Ramps or lifts can provide step-free access, although accessibility depends on the individual facility.

Yes. Users must follow any signs indicating permitted users, direction of travel, separated sections or temporary closures.

Yes. Maintenance, flooding, construction, safety concerns or other circumstances may require temporary closure or diversion.

The underpass physically separates the movements, so pedestrians do not directly cross the traffic route above. Priority rules still apply wherever the pedestrian route later crosses another roadway or cycle facility.

Where cycling is not permitted, cyclists should dismount and continue on foot if pedestrian access with a bicycle is allowed.
