National Highways has confirmed that the A12 will close tonight.
The trunk road will be closed at Martlesham from 9pm on Wednesday and is scheduled to reopen by 5am on Thursday.
The closure is required to allow crews to carry out road marking renewal work, although officials said the road will only need to be shut for part of the advertised hours.
Access for residents and businesses will be maintained throughout the works.
Drivers are being advised to follow a signed diversion route via the A12, A1156, A1189 and A1214 while the closure is in place.
Motorists planning to travel through the area overnight are encouraged to allow extra time for their journeys and check for any updates before setting off.
