The cloverleaf interchange was not implemented in great numbers in the United Kingdom, because of these performance problems. There were originally three, one in Redditch and two in Livingston. One of the Livingston examples was remodeled in the mid-2000s as part of a public transport project. The major junction of the M11 and A14 at the Girton interchange near the outskirts of Cambridge consists of two cloverleaf loops, making essentially a "half"-cloverleaf interchange. This junction is prone to heavy traffic congestion at peak times, chiefly due to the requirement for westbound A14 traffic to exit the main dual carriageway, traverse one of the cloverleaf loops at slow speeds, and then engage in weaving with traffic exiting the M11, in order to continue eastward along the A14. In Ireland, a partial cloverleaf set-up exists at the interchange of the N4 and the M50 in Dublin, allowing free-flow movements in all directions. A similar design has been implemented at the N7/M50 interchange.
