The Tile Hill Gyratory is a complex gyratory system to the south of Coventry where the B4101 crosses the A45. Through traffic on the A45 may navigate the junction without using the gyratory, however most over movements must circumnavigate the junction. It is controlled by several sets of traffic signals and has up to 6 lanes in places. For many years the junction was simply a crossroads between the A45 and B4101 (and for a period, the A4023), however it was later upgraded to the gyratory set-up in use today. In 2008 access from the gyratory to Tile Hill Lane was restricted to buses only to discourage rat-running and several bus lanes were added to the junction.
Several fast food restaurants are located within the centre of the junction, while a large supermarket is located to the south, adding much traffic to the junction. Despite all this, the junction usually flows very well.
