|Junctions on the A3015|
The Sowton Interchange, mostly known as junction 29 of the M5, is the first of two junctions between the M5 and A30 (the other being Pearce's Hill). Between the two junctions, the A30 multiplexes with the M5. It also connects to the old A30, now A3015, which leads into Exeter city centre. It is of a unique design, consisting of four slip roads of various types. The junction was once smaller, with only south facing slip roads onto the M5, forming a modified fork. The junction was altered into its current layout when the A30 was dualled.
The original design for the junction called for two loops on the western side of the junction, allowing traffic on the northbound carriageway to get on and off. Collector/Distributor lanes were planned to link the loops together, to prevent weaving. The only part of this that was built was the northbound offslip.
Further work is currently planned at this junction.
