Menai Strait (mĕnˈĪ) [key], channel of the Irish Sea, 14 mi (23 km) long and from 200 yd (183 m) to 2 mi (3.2 km) wide, between the island of Anglesey and mainland Gwynedd, NW Wales. Thomas Telford's suspension bridge (1826; rebuilt 1938–41) carries the road from Bangor on the mainland to Anglesey, over the strait, and Robert Stephenson's tubular bridge (1850) carries a railroad. Caernarvon is on the strait; Llanfair-Pwllgwyngyll is nearby.
