8. Bridge

A bridge is a structure that carries a road, path or railway over an obstacle such as a river, valley, railway line or another road. A road bridge may carry one or more roadways together with pedestrian or cycling facilities.

Drivers should follow any speed, weight, height, width or vehicle-access restrictions applying to the bridge. Particular care may be necessary on narrow, exposed or movable bridges and when weather conditions such as wind, rain or ice affect the road surface.

What should I check before crossing a bridge in Ireland?

Check the applicable weight, axle-load, width and height restrictions before committing to the crossing. Include the load, trailer and roof equipment when relevant. A bridge warning and a vehicle restriction serve different purposes; comply with both.

Who goes first on a narrow bridge in Ireland?

Follow any traffic lights, give-way controls or signs allocating priority over oncoming traffic. Do not force your way onto a bridge that cannot accommodate both directions safely. A bridge warning alone does not give your direction priority.

May I stop or park on a bridge in Ireland?

Follow the bridge’s signs and the national rules against dangerous or obstructive parking. Do not stop where another driver would have to take a risk to pass, or where you block a pedestrian facility.
