The improvement and maintenance of regional and local roads is the statutory responsibility of each local authority, in accordance with the provisions of Section 13 of the Roads Act 1993. Works on those roads are funded from local authorities' own resources supplemented by State road grants.
Clare County Council is the road authority responsible for the Shannon Bridge Crossing at Killaloe which is one element of the overall Shannon Crossing/Killaloe Bypass/R494 upgrade scheme. The Council is, therefore, best placed to advise the Deputy in relation to the overall history of the project. However, I can advise the deputy that the Government first committed to assist the funding of the project in its capital investment plan for 2016-2021, "Building on Recovery", subject to planning permission.
As regards State grant expenditure on the scheme, this information is included in the Regional and Local Roads Payment and Allocations Booklets which are available in the Oireachtas library.
