Public health officials have appealed to people not to let their guard down as the phased easing of Covid-19 restrictions begins.
The 5km travel limit is among the measures lifted from today, with residential construction work also restarting and all children returning to school.
After more than 100 days of Level 5 lockdown today marks the beginning of the cautious easing of restrictions.
People can now travel anywhere within their county or up to 20km from their home if they are crossing county boundaries.
People from two households can meet up outdoors for social and recreational purposes but this does not include meeting up in private gardens, in order to avoid situations arising where people would gather indoors.
Building work on residential projects can also recommence, as well as construction on childcare and early learning facilities.
An estimated 20,000 construction workers will be back on sites but the same number will remain on the PUP payments as some restrictions still remain, according to the Construction Industry Federation.
For the first time this year there will be a full resumption of in-school teaching as around 300,000 first to transition year students have returned to classrooms.
