The A487 is a major road in the area, running up the west coast. It is a Trunk Road and is therefore administered by the Welsh Assembly Government rather than the unitary authorities through which it passes. It is commonly referred to by WAG as the Bangor-Fishguard Trunk Road.

It starts in Haverfordwest, from where it travels north west, crossing trainlines and rivers emerge just north of Trawsfynydd then passing through Penrhyndeudraeth and Porthmadog.

Between Penrhyn and Porthmadog, the road passes over a mile-long Cob. Until 2003, drivers had to pay a charge to cross The Cob.

The section between Porthmadog and Llanwnda, Gwynedd has, and is still being improved. The new section bypasses Llanllyfni, Penygroes and Y Groeslon, in parts utilizing the old trackbed of the Caernarfon to Afon Wen railway line. In April 2007, the 10 mile new section had to be resurfaced in its entirety after it became apparent that the wrong type of stone had been used for the surface tarmac.

The A487 crosses above the WHR in Dinas village.

A bypass was opened in 1994 avoiding Y Felinheli on the section between Caernarfon and Bangor.

The road terminates at its junction with the A5 close to the mainland end of the Menai Suspension Bridge near Bangor.

It is propsed to bypass Porthmadog in 2009 and at some future point, Caernarfon, from the northern end of the Penygroes bypass to the western end of the Y Felinheli bypass thereafter.
