The closure of Armley Gyratory is set to cause diversions of up to 13 miles and people across Leeds have been warned to plan ahead before travelling this weekend.
The roundabout will be fully closed in Armley from Friday, April 8, from 8pm until Monday, April 11 at 5.30am.
When the road reopens, there will be a 30mph speed limit in place, narrower lanes and other traffic management measures in place that will allow the main improvements to be carried out, says Leeds City Council.
