Project Description

Eirspan Task Order 187 involved inspecting and carrying out stage 1 assessments of 84 structures on National Primary and Secondary roads. The bridges included masonry arches, reinforced and prestressed concrete and composite steel and concrete structures. The bridges date from the 18th century to modern bridges constructed in the 1960's and 1970's.

The assessments were carried out in accordance with the NRA methodology for Stage 1 assessments for a 40 tonne line loading to BD21/01. Where a bridge was found to be substandard for this loading, reccommendations were made for the management of substandard structures in accordance with BD79/06.
