Approximately forty residences will be most affected by the preferred route corridor for the Ballymurray-Knockcroghery and Lecarrow bypass.
The route revealed by engineers last night is C3 which diverts from the current N61 before the railway gates at Ballymurray.
It crosses the rail line and then the existing N61 between Finneran's pub and the Kilteevan turn off just outside Knockcroghery village.
It will then go south through Corbooley and then down to Nolan's Cross beyond Lecarrow village.
Presenting the route to Councillors from the Roscommon and Athlone areas yesterday, NRA officials said it was the best option in terms of the environment and heritage constraints, as well as maximising the potential of an overall upgrade of the route from Sligo to Athlone.
Cathaoirleach Laurence Fallon who lives in the area says it's worth remembering that the route corridor is still quite wide and so people affected need to speak to the project team.
