The Tivoli flyover changes were among several put forward by residents and their legal representatives during the final day of a public inquiry into the massive Cork to Midleton rail link project.
It followed negotiations between residents, their solicitors and Iarnród Éireann during breaks in the four-day hearing at the Midleton Park Hotel.
Inquiry inspector Pat Butler SC heard the company has agreed to meet the concerns of several residents living along the 10km route.
The company will double-glaze the windows of three homes at Killahora which are closest to the rail line and has redesigned the road leading into the railway station at Midleton.
Solicitor Dominic Creedon, representing residents at Myrtlehill in Tivoli, suggested the construction of an automated barrier-controlled level crossing in place of the flyover.
Charles Daly, representing Glounthane residents, raised serious concerns about the impact a bridge over the rail line at Harper’s Island would have on the property value of one of his clients.
Carrigtwohill resident Stephen Smith asked Mr Butler to recommend to the minister the installation of an automated four-barrier level crossing over the rail line instead of a link road at Ballyorchard Mór.
The link road would mean a five-kilometre journey to visit family on the other side of the rail line — a journey that today takes about a minute over an existing level crossing, he said.
