Thursley Interchange is a modified diamond interchange on the A3 in Surrey. The junction was upgraded from an at-grade crossroads as a separate project coinciding with the construction of the Hindhead Tunnel, allowing it to form a suitable diversion route for prohibited traffic in addition to making it a safer route for existing traffic.
The junction is not named on signposts, however signage elsewhere on the A3 refers to it as "Thursley junction".
