List of crossings of the River Thames

The River Thames is the second-longest river in the United Kingdom, passes through the capital city, and has many crossings.

Counting every channel – such as by its islands linked to only one bank – it is crossed by over 300 bridges. If taking cuts – excavated channels – to be measurements of river, its 185-mile (298 km) course west of Tilbury has 27 tunnels, six public ferries, one cable car link, and one ford. From end to end a channel of the Thames can be seen, mostly its main flow, which is passed over by 138 bridges. These are listed here with 2 former bridges and a seasonal festival bridge. Over 162 other bridges link to such places as typical or man-made islands or across an array of corollary and lesser side channels (backwaters), particularly in and around Oxford and the non-village channel of Ashton Keynes — these are not listed.

The river's lower estuary is shallow – but wide – and has no crossing east of Tilbury, the easternmost half as most broadly defined which even extends to the end of the rivers Medway and Crouch.
