The A545 is the only 3-digit road on Anglesey, running along the south coast to the county town of Beaumaris.
Menai Bridge – Beaumaris
The New Cadnant Bridge
The road starts from the Anglesey Arms Roundabout on the A5 just to the north of Telford's Menai Suspension Bridge. It then passes through the town of Menai Bridge along its main street (Telford Road), which is somewhat congested due to parked cars. On leaving the town the speed limit rises from 30 to 40 mph and the road continues on a slightly winding route running along the shore of the Menai Strait. Numerous trees on both sides and a continuous stone wall alongside on the right restrict views.
However, when the road passes Gallows Point on the approach to Beaumaris the view to the right suddenly opens up and the Strait and the mountains of Snowdonia on the far side of it become visible. On reaching Beaumaris the speed limit becomes 30 again. There's a junction on the right with the B5109 which continues along the waterfront whilst the A545 turns slightly inland through the town centre along Castle Street where parked cars again hinder progress somewhat. The B5109 briefly multiplexes with the A545 along the first part of Castle Street before that road turns off to the left. The A545 then passes Beaumaris Castle itself before terminating where it meets the B5109 yet again after that road has run along the town's waterfront.
