Six [[Roads in the United Kingdom#Classification|primary routes]] serve Snowdonia, the busiest of which is the [[A55 road|A55]], a dual carriageway which runs along the north coast and provides strategic road access to the northern part of the national park. The most important north–south route within the park is the [[A470 road|A470]] running from the A55 south past {{lang|cy|italic=no|Betws-y-Coed}} to {{lang|cy|italic=no|Blaenau Ffestiniog}} to {{lang|cy|italic=no|Dolgellau}}. It exits the park a few miles to the southeast near {{lang|cy|italic=no|[[Mallwyd]]}}. From {{lang|cy|italic=no|Dolgellau}}, the [[A494 road|A494]] runs to {{lang|cy|italic=no|Bala}} whilst the [[A487 road|A487]] connects with {{lang|cy|italic=no|Machynlleth}}. The A487 loops around the northwest of the park from {{lang|cy|italic=no|Bangor}} via {{lang|cy|italic=no|Caernarfon}} to {{lang|cy|italic=no|Porthmadog}} before turning in land to meet the A470 east of {{lang|cy|italic=no|[[Maentwrog]]}}. The [[A5 road (Great Britain)|A5]] was built as a mail coach road by [[Thomas Telford]] between London and [[Holyhead]]; it enters the park near {{lang|cy|italic=no|[[Pentrefoelas]]}} and leaves it near Bethesda. Other A class roads provide more local links; the [[A493 road|A493]] down the Dovey valley from {{lang|cy|italic=no|Machynlleth}} and up the coast to {{lang|cy|italic=no|Tywyn}} then back up the {{lang|cy|italic=no|Mawddach}} valley to {{lang|cy|italic=no|Dolgellau}}, the [[A496 road|A496]] from {{lang|cy|italic=no|Dolgellau}} down the north side of the {{lang|cy|italic=no|Mawddach}} to Barmouth then north up the coast via {{lang|cy|italic=no|Harlech}} to {{lang|cy|italic=no|Maentwrog}}. The [[A4212 road|A4212]] connecting {{lang|cy|italic=no|Bala}} with {{lang|cy|italic=no|Trawsfynydd}} is relatively modern having been laid out in the 1960s in connection with the construction of {{lang|cy|italic=no|[[Llyn Celyn]]}}. Three further roads thread their often twisting and narrow way through the northern mountains; [[A4085 road|A4085]] links {{lang|cy|italic=no|Penrhyndeudraeth}} with {{lang|cy|italic=no|[[Caernarfon]]}}, the [[A4086 road|A4086]] links {{lang|cy|italic=no|Capel Curig}} with {{lang|cy|italic=no|Caernarfon}} via {{lang|cy|italic=no|Llanberis}} and the [[A498 road|A498]] links {{lang|cy|italic=no|Tremadog}} with the A4086 at {{lang|cy|italic=no|[[Pen-y-Gwryd]]}}. Other roads of note include that from {{lang|cy|italic=no|Llanuwchllyn}} up {{lang|cy|italic=no|Cwm Cynllwyd}} to {{lang|cy|italic=no|[[Dinas Mawddwy]]}} via the {{convert|545|m|ft|abbr=off}} high pass of {{lang|cy|italic=no|[[Bwlch y Groes]]}}, the second highest tarmacked public road in Wales and the minor road running northwest and west from {{lang|cy|italic=no|Llanuwchllyn}} towards {{lang|cy|italic=no|[[Bronaber]]}} via the {{convert|531|m|ft|abbr=off}} high pass of {{lang|cy|italic=no|Bwlch Pen-feidiog}}.
