Bridge strengthening

Assessing and strengthening bridges to comply with European Union requirements.


All road bridges in Suffolk have been assessed to check if they have the capacity to carry 40 tonne lorries as required by the European Union (EU).

Suffolk County Council is responsible for the maintenance of road bridges, except for  trunk roads which are managed by W S Atkins on behalf of the Highways Agency.  Any questions regarding bridges on trunk roads should be directed to W S Atkins rather than Suffolk County Council.

Where road bridges are not up to strength Suffolk County Council may:

  • impose a weight restriction;
  • monitor the bridge for signs of damage;
  • replace the bridge; or
  • strengthen the bridge.


There is a formal mechanism for determining priorities; bridges on busier roads or with unsuitable alternative routes will normally take priority.  A programme of work is planned several years ahead, but can be changed year by year if priorities change.
