OB702 Roscommon Bridge Widening & Road Alignment

The existing bridge OB702 was widened to take the skew out of the road. The overbridge comprised of Opti-Cadre units and reinforced earth abutments.

The bridge was widened to the Claremorris side by approximately 10.5m while leaving the existing structure intact and maintaining traffic flow. The reinforced earth walls were constructed with little interference to the existing passing traffic and the railway line. Other works included palindine fencing, high level safety barrier and road surfacing. The work was necessary to create a straight road across the railway line to enable all local traffic to traverse the bridge safely. This project was the first of its type to use Opti-Cadre units to extend an existing bridge.

The geogrid used here was Enkagrid Pro 90 which worked well with the poor ground conditions. The existing level crossing gates were replaced with blockwork wall & a double palisade access gate. A precast concrete culvert, supplied by Banagher Concrete, was installed to replace an existing culvert crossing the new access road.

Noone’s UB121, Rineen, Gort, Co. Galway

At this site Existing Level Crossing’s XE128 & XE129 were closed and replaced by a 4.50m x 4.50m internal dimension under-bridge, 20m long. The under-bridge was a contractor designed structure.

500m long new access roads were also constructed The installation of the under-bridge took place over 2 days, from 7.00 am Tuesday 16th of June 2009 to 6.00pm on Wednesday 17th of June 2009. The under-bridge is made up of 15no U shaped duct units each weighing approx 20t (i.e. 8no base units and 7no top units). A 350 ton crane was used during the installation both for lifting /replacing the track and also for installing the units.

On day 1, the track was removed, excavation completed, and preparation of base for unit’s. On day 2 the precast units were installed. All sealants and waterproof membranes installed and completion of stitches between units together one erection of temporary handrails.
