Railbridge RB287 N7 HQDC

Railbridge RB287 N7 HQDC (High Quality Dual Carriageway)

The RB287 Bridge project involved work over a live Irish Rail, railway line. Works carried out included the following:

  • Part demolition of the existing bridge which was carried out by hydro-demolition
  • Widening of the structure
  • Beam placement
  • Deck widening
  • Waterproofing
  • Surfacing
  • Bearing replacement;
  • Resurfacing
  • Whiteling (Painting)
  • Construction of a high speed vehicle barrier;
  • Traffic Management.

Throughout the project traffic management was extremely pertinent, the main challenge was keeping the route live for both vehicles and trains and ensure maximum health and safety at all times. This involved constant liaising and additional training with Irish Rail.
