Pending strengthening, public safety is maintained on those bridges assessed as weak by using temporary weight restrictions or other measures and restrictions.
Work carried out under the strengthening programme gives priority to principal road bridges. For substandard bridges on the non-principal road network, decisions are made whether to permanently weight restrict rather than strengthen. Each bridge is considered on its merits taking into account safety, economic and environmental factors.
How often are they inspected?
- All highway structures have:
- general inspection every two years
