Sections of the White Hart roundabout will be closed to motorists as overnight work takes place tonight.
Swindon Borough Council said Osborne Infrastructure Ltd, the contractor for the junction improvement project, will be installing traffic light loops which will lead to the closure of various parts of the roundabout.
The A419 southbound off-slip will be closing 8pm to 6am tonight and tomorrow night and the northbound main carriageway, from White Hart junction to the Rat Trap will shut from 8pm until 6am tomorrow.
Anyone driving in that direction is encouraged to use the signposted diversion route.
The roundabout reopened in November after months of closure but more work is needed on the junction as a whole and this work it part of it.
