Why did they not allow direct access to Airside from the M1 northbound?

I was thinking about this today as I joined the M1 SB from Airside. I accept it's probably a dumb question.

If I was to guess I would say motorway design does not favour having lots of exits in close proximity?

Cheers.

Either that or maybe to stop it being used as a shortcut to the pavilion shopping centre

Unless I have read the title incorrectly, you can enter Airside directly (well as direct as is possible) from the M1 north bound, at the same junction that you entered the M1 south bound

No, there is no exit for Airside on the M1 NB but there is access to M1 SB from Airside. To get there from the city, you would probably need to exit at the airport and drive up....not really an issue to be honest. I just found myself wondering that's all!

I think you're causing a bit of confusion here. You can get to Airside from city via the M1. You don't need to exit at the airport.

Sorry I'm not used to this part of the city. I merely observed while heading into the city from there yesterday, that there is an exit onto the M1 SB a couple of minutes away..,,but no NB access at the same location.

This is Airside Business Park in Swords yes?

If so it does have Northbound access from the M1, you take the swords exit.

There are very few motorways across the country that you can't access an exit from both sides of the motorway.

What is it you're trying to say, you can't go North bound from Airside?

The title should have 'Southbound' instead of 'Northbound'

Or

Why did they not allow direct access from Airside to the M1 Northbound.

Which one you do mean OP?

OP is asking why you cant exit the M1 coming from the North Direction to gain access to Airside.

I've always wondered why the Drinan partial interchange was built. It's very close to the Airport junction and I've always thought it was rather unnecessary. It reeks of a developer-led rather than planning-led motorway access IMO.

How does it reek of a developer-led plan? The interchange serves the huge population of Holywell and even Waterside trying to access the M1 in the morning (or coming home in the evening) who would otherwise clog up the R132.

OP the reason it only serves the city is because that's where the majority of traffic using the junction are going to or coming from.

Ideally, non-urban motorway junctions should not be located too close together - this compromises the capacity and the functionality of the motorway.

I would have thought that an interchange at the Swords-Malahide road would have made more sense than one at Drinan.

I doubt the population of Holywell would in itself merit access to a major motorway.

TRAFFIC movements on the new M1 Motorway do not require more than a half interchange at Drinan, the council has said.

The proposed half interchange at Drinan will mainly facilitate city traffic trying to access Swords. Drivers coming from the north and travelling into Swords will still exit the motorway at the Lissenhall Interchange.

‘When the scheme was initially examined it was discovered that traffic travelling from the north would easily access Swords via the Lissenhall Interchange,’ said Peter Caulfield, Senior Executive Officer in the Transportation Department.

Cllrs Anne Devitt and Cathal Boland both questioned Mr Caulfield why a full interchange was not deemed necessary at Drinan.

Mr Caulfield continued: ‘Existing traffic movements and predicted future movements on the M1 did not necessitate more than a half diamond interchange at Drinan.

‘It wasn’t considered and it still isn’t considered that more than a half interchange is needed at Drinan because of the easy access for northern traffic to Swords from the Lissenhall Interchange.

’Traffic travelling south to Swords from the north would be going back on themselves if they were to use the Drinan Interchange.’

The Drinan Interchange involves a half interchange on the M1 with two south facing ramps, merge/diverge lanes and a motorway overbridge. One kilometre of four lane single carriageway link road will be constructed.

Geometric improvements will also be carried out to the existing roundabout at Pinnock Hill where the connecting route from Crowcastle links to the existing N1 at the southern end of the Swords By-pass.

An Bord Pleanála has approved the scheme without modification. Consultant engineers Roughan and O’Donovan have been retained by the local authority to bring the Drinan scheme through the design and construction phase. Documentation is being prepared to enable the scheme to be put to tender.

The expected time for commencement of construction is September 2004.

The Drinan interchange will east traffic congestion problems in the centre of Swords village. The interchange will provide a direct link from the M1 Motorway onto the N1 road at Crowcastle, beside the Little Chef Restaurant.

The already-built Boroimhe Distributor Road will then allow vehicles to bypass Swords village straight onto the Forrest Road.

Serves me coming from Malahide too - something like 35 sets of traffic lights in my way if I head to college via the Malahide Road, which i point blank refuse to fight my way past. I generally use it off-peak and it means I'm in town in 20 minutes or even less at night via this junction.

Developer-led it may have been, but it's a hugely useful junction and should be bi-directional. It's not too close to the Airport junction as to be unsafe - what causes collisions is the lack of a lane drop arrangement and blithering idiots hogging the middle lane of the M1NB after the airport, causing people to cut across two lanes, amid the approach to a high-speed lane drop no less.

No offense to anyone, but I think this thread has well run its course!

I think that kind of went without saying considering there hadn't been a post for three days.
