The Chelston Interchange is junction 26 of the M5. It is the main access for the town of Wellington, Somerset to the motorway. It is also signposted to Taunton for northbound traffic, as it is considerably easier to reach parts of the county town from here than to deal with the often congested Blackbrook Roundabout further north. The A38 present here is a spur, and links back to the mainline at this roundabout's older sibling, Chelston Roundabout. The spur was until recently an S3 road, but was altered to S2+1 in 2009.
Previous SABRE research found a line of bore holes from this junction, leading along the A38 spur, that were dug for part of the A361 North Devon Link Road project. No further evidence of this line for the NDLR has been found, suggesting the plans were dropped very early on.
