The N31 road is a national primary road in Ireland. It connects the port at Dún Laoghaire southeast of Dublin to the national route network. Both the N11 (Dublin – Wexford) and Dublin's M50 C-ring motorway connect to the N31.

Route

N31 Blackrock By-Pass

With the completion of the Southeastern Motorway section of the M50 in 2005, the N31 was extended to connect to it. As of 2006^[update], the N31 begins at J14 on the M50. Leopardstown Road and Brewery Road bring the N31 northeast to join the N11 Stillorgan Road southeast of Stillorgan.

The route diverges from the N11 again further north as Mount Merrion Avenue, bringing the N31 east to the sea front. From here, the N31 passes through Blackrock via Frescati Road/Blackrock By Pass; (see thumbnail) alongside Monkstown via Temple Road, Newtown Avenue and Seapoint Avenue; and to Dun Laoghaire via Dunleary Road and Crofton Road.

Upgrades

The route was revised in 2005/2006 to include a new section between the M50 and N11. No further planned amendments to the route have been publicised as of 2006, but the N31 would be affected in the event of an Eastern Bypass of Dublin. The current M50 would connect at the southern end of this via a link on a similar alignment to the first half of the current N31.
