Over 900 submissions were made after the public consultations on the N2 realignment scheme held last year.
Just over half were submitted by people living close to one or more of the route corridor options.
Public consultations were held in October and November of last year with six Route Corridor Options for consideration.
934 submissions were received by Jacobs Consulting who are working on behalf of Monaghan and Louth County Councils and TII.
763 of the respondents live or have land close to the proposed routes.
A large number of respondents advocated upgrading the existing N2 and making the route safer, rather than building a new road. Measures including restricting the number of junctions or access points onto the road were suggested.
Concerns over noise, air quality, biodiversity and climate change were also raised among the submissions.
Preferred route options for the two sections of the N2 being examined, from Ardee to Castleblayney and Clontibret to the border, are expected to be published later this year.
