The M50 motorway ( Ireland ) | M50 motorway surrounding Dublin.

It now acts as a shopping and service centre, and as a focus of educational and cultural activities, for its surrounding rural area, and is linked by the A40 road to the M4 motorway at Newport and the M50 at Ross-on-Wye.

Monmouth is located beside the A40 dual carriageway road that links the M4 motorway at Newport in South Wales with the M50 motorway at Ross-on-Wye ; this connects in turn with the M5 motorway south of Worcester in the West Midlands.

The northern frontier of the Pale was marked by the De Verdon fortress of Castle Roche, while the southern border roughly corresponds to the present day M50 motorway in Dublin, which crosses the site of what was Carrickmines Castle.

Notable are the West-Link Bridge on the M50 motorway, the Seán Heuston Bridge and O ' Connell Bridge.

A new bridge was built in the early 1970s to carry this line over the M5 motorway, just north of junction 23, when the M5 was extended southwards from its terminal junction with the M50 motorway.

It then connects with the M50 motorway, and then forms part of the high quality dual carriageway between South Wales and the West Midlands.

The M50 motorway () is a motorway in Ireland running in a C-shaped ring around the north-eastern, northern, western and southern sides of the capital city, Dublin.

The completed M50 motorway was formally opened on 30 June 2005, and later the Dublin Port Tunnel, which was opened on 20 December 2006, was included as part of the route.

At the Dublin Port Tunnel portals, the road follows the M50 motorway for 2 km, before the M1 motorway begins at M50 Junction 3.

A couple of kilometres from Dublin Airport, it is situated at Junction 5 of the M50 and the N2 national primary road leading to Ashbourne and beyond.

) It runs from the northernmost part of the M50 ring road in Dublin, north of Dundalk, bypassing the intermediate towns through which the original route travelled.

* M50, 45km C-shaped ring road that forms a bypass of Dublin.

However in 1994, following the construction of the Chapelizod bypass which brought the N4 road in to Dublin city centre as dual carriageway, the N7 inside the M50 was downgraded to regional road status ( as the R110 road ), with N7 traffic being signposted to use the N4 and M50 rather than the original route through Inchicore.

Along the Shankill Bypass, the M11 is joined by the Dublin's M50 motorway ring road, which terminates at a major junction along the M11, opened in June 2005 after many years of planning.

The M50 runs in a southwesterly / northeasterly direction between the M5 motorway just north of Tewkesbury and the A40 road and A449 road at Ross-on-Wye.

Blanchardstown is just outside the city's M50 motorway ring road, slightly to the north of the tolled crossing of the River Liffey.

The road has three lanes and a bus lane in each direction between the M50 and start of the M4 at Leixlip.

The Dublin Port Tunnel ( Irish: Tollán Chalafort Bhaile Átha Cliath ) is a road traffic tunnel in Dublin, Ireland, that forms part of the M50 motorway.

The M50 ring road around Dublin has since been widened to 4 lanes ( 3 running lanes and 1 interconnecting lane between exits ) in each direction and all of the interchanges are free-flow or partially free-flow since the end of 2010.

The village is located just inside the city's M50 motorway ring road, bordered to the west by the large suburb of Blanchardstown, to the east by the Phoenix Park, to the north by Dunsink and to the south by the village of Chapelizod above the Liffey valley.

The last major use was the M50 Ontos, which mounted six of the US 106 mm on a light ( 9 ton ) tracked chassis first developed for use by the US Army airborne troops in 1950.

The original speed limit on the M50 was 70 mph ( 112 km / h ) which was increased to 120 km / h when all speed limits in the Republic of Ireland became metric in 2005.

The section of the route which was previously the M1 from Junction 1 to Junction 3 ( which is now the M50 up to the port tunnel ) retains a speed limit of 80 km / h due to the closely packed junctions, and because of the high number and frequency of lane changes that are required among all manner of vehicles depending on their intended route.

* M4, part of the DublinSligo route: from Lucan ( on N4 from M50 J7 ) to Kinnegad at which point it reverts to dual carriageway to ( bypass ) Mullingar.

The N7 is the only one of the inter-urban routes out of Dublin which does not commence in Dublin city centre, but rather at the M50.

Traffic proceeding north on the M11 is given a choice to stay on the main carriageway ( which becomes the M50 ), or take the exit at what is junction 17 on the M50, in order to stay on the M11, following the N11 into the city centre.

Just to the east of town is the end of the M50 " Ross Motorway " spur from the M5 motorway which links the area to the UK motorway network.

The ' area ' is administered both by Dublin City Council ( formerly Dublin Corporation ) and Fingal County Council, responsible for 84 % and 16 % of the land area which lies inside the M50 motorway and north of the river Liffey respectively ( excluding the Howth peninsula ).

In 1994, the possibility was raised of upgrading the whole of the A465 to 2-lane dual carriageway standard with grade-separated junctions ( and extra climbing lanes on certain hills ) between Abergavenny and Hirwaun, a stretch connecting the existing A465 dual-carriageway link to Swansea and the M4 motorway to the A40 which is an important part of the link to the M50 motorway and much of England.

One of the upgrades was the M50 Dublin Port Tunnel project which was a major scheme involving tunnelling from the M1 north of the city centre, through to the Docklands to the east of the city centre.

The BMW M50 is a straight-6 DOHC piston engine which replaced the BMW M20 and was produced from 1990 to 1996.

The E36 M3 was powered by the S50 engine series, which is based on the M50.

The BMW M52 is a straight-6 DOHC piston engine which replaced the M50 and was produced from 1994-2001.

Compared with its M50 predecessor, the M52 uses an aluminium block ( except for North American models, which retained the iron block ).

* The Irish Mint, a division of the Central Bank of Ireland, which has been in operation since 1976 is located in Sandyford, west of the M50 and north of the village.

The " Next Exit " signs listing destinations, which were originally used only on the M50, are now extended to other motorways.
