Transport Infrastructure Ireland (TII) says it has virtually no remaining options to ease severe congestion on the M50, acknowledging that the motorway has hit its limit.
“We’re actually beyond the Celtic Tiger numbers, we’re at capacity. We can’t make it any wider, and you can’t make it a double decker,” TII’s Director of Corporate Communications Sean O’Neill told *Prime Time* during a report assessing how the motorway functions and what measures could improve traffic movement around the Dublin commuter region, reports RTE.
A record 187,284 vehicles travelled along the section between Junction 6 Blanchardstown and Junction 5 Finglas on 26 June this year, the highest daily count ever.
Regular M50 users say the route has become increasingly unreliable, with trips that previously lasted under an hour now taking far longer, reports RTE.
The Irish Road Haulage Association (IRHA) has described the M50 as “no longer fit for purpose”, warning that delays on the motorway are adding to inflation for consumers.
Some drivers are spending more than three hours each day commuting on the M50 to and from their workplaces, reports RTE.
Traffic control specialists note that congestion patterns have shifted, with rush-hour periods starting earlier and lasting longer than they did in previous years.
Live camera feeds from 100 locations along the M50 are monitored at TII’s Motorway Operations Control Centre near the Dublin Tunnel entrance in East Wall, reports RTE.
Daniel Pentony, TII’s Motorway Operations Manager, said that morning and evening peak times have extended considerably. As an example, he noted that Friday rush hour now begins shortly after midday.
The heavier traffic on Ireland’s busiest motorway has also resulted in a rise in crashes, reports RTE.
“We’ve had the same number of collisions for the first ten months of this year, compared to all 12 months in 2024,” Mr Pentony said.
“A lot are to do with driver behaviour and motorists being distracted on their mobile phones. And there’s rubbernecking of incidents where drivers are seeing something in the opposite carriageway and not paying attention,” he added, reports RTE.
Incidents ranging from breakdowns to fatalities are managed by the M50 Incident Support Unit, which has teams positioned across the motorway to respond as quickly as possible.
Ryan Mulroy, who has spent 13 years working with the response team, said they “could have anything from ten to 20 call-outs per day”, reports RTE.
“We usually take between 13 to 18 minutes to get to any incident on the road. We have four trucks and four vans on the road at any given time, so we are able to get out to the incidents fairly quick,” Mr Mulroy added.
Even with swift response times, many believe that even a minor crash on the M50 during rush hour can paralyse traffic across Dublin, causing major disruptions for businesses that depend on the motorway, reports RTE.
“It is Russian Roulette. It’s a roll of the dice when you come onto it,” said Noel Whelan, who runs the DPD Ireland parcel depot in Balbriggan, north County Dublin.
That depot is one of seven the company operates across Dublin, and its 300 delivery vans move on and off the M50 constantly. Predicting delivery times is essential for the business, yet congestion makes that extremely difficult, reports RTE.
“If there is an incident on the M50, that cascades onto the ancillary routes coming on and off it. That just affects every part of the business and you cannot keep on time,” Mr Whelan said.
“There is no rhyme or reason to it. There is no two days the same on it. Anything can happen,” he added, reports RTE.
Mr Whelan also argues that poor driver behaviour plays a major role in the ongoing traffic problems.
“I commute 450km a week along the M50 and you see everything. You see every kind of bad behaviour from mobile phone use, eating, putting on makeup, tailgating and speed,” he said, reports RTE.
The traffic pressure on the M50 spills onto many other commuter routes feeding into Dublin.
Tara McManus, who lives in Mullagh, Co Cavan, drives daily to Phibsborough in Dublin, where she works with the Garda Representative Association, reports RTE.
She uses the M3 motorway, which—like routes such as the M4, M7 and N2—becomes backed up from around 6.30am for roughly three hours as traffic funnels towards or across the M50.
“It is getting progressively worse all the time. And it’s just really draining. It’s a lot to do before you go in and do a day’s work,” Ms McManus told *Prime Time*, reports RTE.
She drops her four children to the school bus at 7.45am before beginning the 70km trip to Dublin, passing two toll plazas in each direction, which costs her about €6 per day.
“It can be anywhere from an hour and 20 minutes to over two hours,” she said, reports RTE.
The pressures facing motorists and employers reflect broader changes in the Dublin region, according to Professor Aisling Reynolds-Feighan, a transport economist at UCD.
