About us

A small site about a large network

m50nline is an information project based in Clontarf, Dublin. We write about Ireland's roads, tunnels and bridges, and about the places you reach along them.

This site is not a road operator's site, a travel company's site or a state body's site. It is a small independent publication that tries to describe the infrastructure around us in a way that is clear, and that is of use to someone who is interested in it.

The work begins with a simple question: what can be said with confidence? We can describe the character of a road, the way a tunnel works, the kind of signage you will see. We cannot say that your journey will be clear, and we do not attempt to say so.

That approach is so central to what we do that we have given a separate page of its own to the editorial policy, which describes how material is chosen and how it is updated.

What we do

Describing infrastructure

How motorways, tunnels, bridges and tolling systems work.

Context for routes

How road numbers are read and what they mean.

Practical guidance

How to plan a journey and what you should check.

Places and context

What there is to see along the routes, without commercial recommendations.

What we do not do

We do not sell tickets, we do not make bookings, we do not accept payments and we do not provide travel services. We hold no toll account and we cannot help with appealing a fine or with resolving a question about a payment.

We do not give legal advice, safety advice or official traffic guidance. We are not affiliated with Transport Infrastructure Ireland, the National Transport Authority or any road body.
