In

The existing R498 at Latteragh is a single carriageway section which follows the contours around the Latteragh hills, adjacent to the meanders in the Nenagh River. This has led to the road having a sub-standard cross-section and has resulted in numerous collisions.

TOBIN Consulting Engineers has developed the scheme in accordance with Transport Infrastructure Ireland (TII) publication Project Management Guidelines (PMG) through Phases:

  • Phase 2 Route Selection
  • Phase 3 Design
  • Phase 4 Environmental Assessment Reports and Statutory Process.

TOBIN established the constraints for the area, developed assessed route options for improvement, assessed the preferred route, prepared the Part 8 Planning and Environmental documents and post Part 8 approvals and prepared the CPO drawings and schedules.

The R498 Road Realignment at Latteragh is approximately 4.5km in length to improve the narrow substandard road with a Type 3 Single Carriageway cross-section.
