Prior to the construction of the M6 motorway the R446 formed the main N6 road connecting Dublin and Galway (via the N4 at Kinnegad).  Following the opening of the M6; the old N6 road was downgraded to regional road status and was designated as the R446.  The road is an alternative route between Galway and Dublin and runs in parallel to the M6.

Thelwall Viaduct: The Thelwall Viaduct (grid reference [ SJ664883] ) is a steel composite girder viaduct in Lymm, Warrington, England.

Brockholes (nature reserve): Brockholes is a nature reserve near Preston, Lancashire, England, just off Junction 31 of the M6 motorway.  It is owned by the Wildlife Trust for Lancashire, Manchester and North Merseyside.  Situated in the flood-plain of the river Ribble, it has the UK's first floating visitor village.

N6 road (Ireland): The N6 road is a national primary road in Ireland from junction 11 on the M4 motorway at Kinnegad to Galway city.  The N6 and N4 form a continuous motorway or dual carriageway from Dublin city centre to Galway City passing in an east–west direction through the midlands of Ireland.  Most of the road is motorway standard (designated as M6 motorway) with the exception of the Athlone bypass and stretches of urban road in Galway City, which are the only sections of the road that remain designated as N6 dual carriageway.  There is one toll on the road outside Galway city.  Major upgrades to the road were completed in December 2009 completing the first intercity motorway/dual carriageway in Ireland.

It is located about 4 miles (6 km) north of Carnforth, and approximately 0.5 miles west of the Village of Burton in Kendal of which it takes its name.  It is accessible to northbound traffic only, with southbound traffic having to use Killington Lake services (southbound only) about ten miles north (or the facilities in the town of Carnforth just off the motorway).  It opened on 23 October 1970, operated by Mobil Motorway Services.  It is currently operated by Moto.

Clawthorpe: Clawthorpe is a hamlet in the South Lakeland District, in the county of Cumbria.  It is near the village of Burton-in-Kendal and the town of Kendal.  Clawthorpe is on the A6070 road and nearly on the M6 motorway, but there is no access to Clawthorpe from the M6 motorway.

Here, just short of the Scottish border it becomes the A74(M) which continues to Glasgow as the M74.

Todhills Rest Area: Todhills Rest Area is a rest area in between Junctions 44-45 of the M6 motorway in England.  It is the last Services northbound on the M6 and the first southbound.  It was first opened in the 1980s on the A74.  When the M6 was extended in 2008, it was initially believed that Todhills would need to close so the road could be widened, but this did not prove to be the case, and the widening scheme was completed without having to close the rest area.

M6 motorway (Ireland): The M6 motorway (Irish: "Mótarbhealach M6" ) is a motorway in Ireland, which runs (together with the M4) from Dublin to Galway.  The M6 extends from its junction with the M4 at Kinnegad all the way west to the outskirts of Galway City, but the Athlone bypass and the approach to Galway city - while of dual carriageway standard - have not been designated motorway and are still signed as N6.  The motorway was officially completed and opened to traffic on 18 December 2009, and was the first city-to-city direct major inter-urban route to be completed in Ireland.  The M6 and M4, which form the Galway-Dublin route, consist of a grade-separated 2+2 dual carriageway road with a top speed limit of 120 km/h.  At approximately 144 km (90 mi), the M6 is the third longest motorway in the state.

Preston By-pass: The Preston By-pass was Britain's first motorway.  It was designed and engineered by Lancashire County Council surveyor James Drake as part of a larger initiative to create a north-south motorway network that would later form part of the M6 motorway.  The by-pass was opened on 5 December 1958 by the Prime Minister, Harold Macmillan.  Nearly £3 million was spent in its construction.  The original 8 ⁄ -mile (8.26 mi ) motorway ran around the east side of Preston between Bamber Bridge (now the M6, Junction 29) and Broughton (now the M55, Junction 1) and crosses over the River Ribble at Salmesbury at the M6 Junction 31.
