The Chief Executive of the National Transport Authority has said there will be changes made to the proposed Bus Connects plan for the greater Dublin area when a revised plan is published next year.
The National Transport Authority said it received 20,000 submissions from the public ahead of today's deadline.
NTA Chief Executive Anne Graham said the original plan to implement Bus Connects has been delayed until 2020 as a result.
A number of councillors and local activists have handed in submissions about the BusConnect proposals in person at the headquarters of the National Transport Authority.
The group said they were passing on the objections of residents in their local communities to the proposals and that they hoped their objections would be listened to.
Ms Graham has said the volume of proposals meant that it would be several months before they could all be considered and therefore it would be next year before revised plans could be published.
Ms Graham said the fundamentals of the plan would not change, but that interchanges with already congested rail services and the abolition of some local routes would be reversed.
She said she was not surprised by the amount of "engagement" the NTA had received about the proposals.
Ms Graham said 92% of people will keep their direct service to the city centre but that the redesign would impact on some local services and require more interchange.
She said the NTA has met 15,000 people to discuss the plans in what she believes is one of the biggest consultations regarding a public service ever undertaken.
The National Bus and Rail Union said it was convinced the redesign of the network was aimed at keeping services out of the city.
Speaking on RTÉ's Morning Ireland, NBRU General Secretary Dermot O'Leary said Bus Connects had not been thought through properly.
He said: "We are convinced that this plan is designed to keep services out of the city and from crossing the city.
"This plan is going to discommode hundreds of thousands of people, schoolchildren with their direct services, people with disabilities, people with accessibility problems, and again I think this hasn't been thought out properly.
"But we are hopeful that today being the last day of the public submissions ... that people will go back to the drawing board."
Mr O'Leary said he hoped that the NTA would now engage with the NBRU, commuter groups and residents' associations to develop a plan.
