Project Overview

Project Title
N2 Blackwater Bridge Replacement Scheme, Monaghan

Project Description
Blackwater Bridge is located on the N2 just North of Monaghan Town, Co. Monaghan. The structure carries the N2 over the Black-water River. Blackwater Bridge comprises an original three span (4.26m, 4.21m and 4.23m) masonry arch structure extended on the downstream side with a three span (4.49m, 4.24m and 4.28m) reinforced concrete slab structure. The entire bridge will be replaced with a new three span reinforced concrete slab, fully integral at the new abutments and semi-integral over the new piers. To accommodate future hydraulic capacity requirements, the new bridge will be set high-er than the existing structure, requiring a rea-lignment of the vertical geometry of the N2, for approximately 150m on either side of the bridge.
