The A5 road upgrade between Aughnacloy and Derry has been given the go-ahead despite more than 2,000 objections.
The findings of a public inquiry were leaked to the media ahead of publication.
Stormont would neither confirm nor deny the recommendations of the inquiry. Campaigners are now considering a challenge to the findings.
John Dunbarr, chairman of the A5 Alternative Alliance said residents living along the proposed route were vehemently opposed to the new road.
“We see no benefit in the proposed road and the people living along the 55 miles will see no benefit at all.
“They will only see farms severed, seven homes demolished and communities split.”
However Foyle MP Mark Durkan said the road upgrade was essential if business between Dublin and Derry was to grow and flourish
Mark Durkan thinks the road is vital for future prosperity.
He said: “It is an important commercial route, an important public service route, not least in terms of hospital services and connections.
“It the towns in the west are to grow and do well, they need good infrastructure connecting them so that investment is hugely important.
“Whatever difficulties in relation to particular businesses and in relation to farms, the fact of the matter is, the progress of the west needs that route to be upgraded.”
