The Ace of Spades junction is in Hook in the Royal Borough of Kingston upon Thames.

It enables the A243 Hook Road to cross and link to the A3 Portsmouth Road, and two sliproads interface with, just west, the London end of the A309 Kingston Bypass which serves Esher and Hampton Court Bridge.

It takes its name from a once well-known 1930s roadhouse,[1] a pioneer establishment, serving meals 24 hours a day in a restaurant with seating for up to 800, dancing until 3am, large outdoor swimming pool, a miniature golf course, polo ground, riding school and an airstrip.

[5] In the months after opening it attracted motorcyclists keen to ride the underpass at high speed.

Today there is a traffic "black spot", during peaks, going northeast before the "underpass".
