Cardinham Downs Junction, also known as Trewardale Junction in local news reports, is a junction currently being rebuilt on the A30, north of the village of Cardinham, Cornwall.

The new incarnation of the junction is being constructed as part of the Temple - Higher Carblake Dualling scheme, removing the single carriageway bottleneck from the A30. It marks the most westerly point of the scheme and is a Compact Grade Separated Junction, meaning simple give way entries onto the A30.

The junction started out as a simple T-Junction at Classification, only having its layout changed when the A30 was dualled up to here from the Bodmin Bypass in the 1970's when it became a simple at grade junction with a gap in the central reservation. To improve access to the local services and to keep local and long distance traffic separated, as well as closing one of only a few central reservation gaps on the A30, the decision was taken to grade separate the junction.
