Tunnel design
The tunnel is {{cvt|260|m|yd}} long and consists of a single bore of diameter {{cvt|2.96|m}}. It was built in pipe-jacking using a Herrenknecht tunnel-boring machine and {{cvt|2.5|m}}-long precast reinforced-concrete pipes. The tunnel leads from the southern edge of the East Link Bridge, underneath the River Liffey towards the North Quay Wall, approximately {{cvt|150|m|yd}} west of 3Arena. The drive and reception shafts are respectively {{cvt|19|m}} and {{cvt|22|m}} deep, leaving the tunnel passing approximately {{cvt|8|m}} below the shipping channel of the river.{{citation needed|date=November 2017}}
