► N60 Castlebar Balla Road (Manulla) Improvement Scheme


Mayo National Roads Design Office (MNRDO), in conjunction with Mayo County Council and the National Roads Authority (NRA) are in the process of planning the N60 Castlebar Balla Road (Manulla) Improvement Scheme which commenced in January 2011 following an allocation of funding from the National Roads Authority.

The Project involves the construction and improvement of approximately 4.0 km of road infrastructure for the N60 National Secondary Road between the townlands of Manulla and Carrowntober Oughter, Balla in County Mayo.

Jacobs Engineering Ireland Limited (Jacobs Engineering) were appointed by Mayo County Council to undertake the planning and design of the new N60 Castlebar Balla Road (Manulla) Improvement Scheme.

Jacobs Engineering identified a Constraints Study Area and developed six route option corridors for the Project within the Constraints Study Area.

Mayo County Council displayed the six feasible route options at a public consultation for the Project which was held on 19th August 2014 in Manulla Community Centre. A brochure and questionnaire were also available at the public consultation.

Submissions and observations, in writing, were invited from all interested groups or individuals regarding the route corridor options.

Route option drawings, brochure and questionnaire relating to the public consultation can be viewed by clicking on the following links:




Following public consultation feedback, a further route option was introduced as a combination of Options 1 and 6. This additional Option, titled Option 7, was then included as part of the Route Selection Appraisal Stage where the seven route option corridors were subjected to further detailed studies in order to identify a single preferred route for the Project.

A draft Alternative Assessment Report (AAR) was prepared by Jacobs Engineering which assessed each of the seven route options under the four criteria of Environment, Engineering, Safety and Economic and identified a preferred route corridor.

Option 6 was identified as the Emerging Preferred Route Corridor.

As a continuation of Phase 2 (Route Selection) Mayo County Council displayed the Emerging Preferred Route Corridor to the general public at a public consultation which was held on the 26th May 2015 in Manulla Community Centre.

The Emerging Preferred Route Corridor drawings and the brochure relating to the public consultation can be viewed by clicking on the following links:


Following the public consultation the draft Alternatives Assessment Report (AAR) was updated and the final AAR was issued by Jacobs Engineering to Mayo NRDO on 2nd June 2015.
