Communities in Rathowen and Ballinalack are pressuring the government to intervene.
Communities in Westmeath are joining forces to lobby Transport Infrastructure Ireland in a bid to stop speeding in their towns.
Rathowen and Ballinalack have seen a number of accidents in recent years on the N4.
A severe crash in Rathowen which hospitalised two men, prompted locals to hold a meeting about possible speed reduction measures last Wednesday evening.
Engineers from the local authority will meet with campaigners before a proposal for TII is drafted.
The campaign group also wants to meet the Minister for Transport to secure funding.
Fianna Fail Longford-Westmeath TD Robert Troy attended the meeting and says they're determined to do what they can:
