A303 shut between Sparkford and Ilchester this weekend
The stretch of road is to become dual carriageway
National Highways are shutting the A303 in both directions between Sparkford and Ilchester this weekend as part of major upgrades.
They'll be changing the road layout around the Steart Hill Junction and Gason Lane as they work to make it a dual carriageway.
A signed diversion will be in place during the closure, which'll be in place from 9pm tonight until 6am on Monday.
According to the Highways Agency, eastbound traffic will be moved onto a single lane of the new westbound carriageway at Steart Hill through to Gason Lane and then back onto the existing A303.
Westbound traffic will switch from the existing A303 westbound carriageway at Gason Lane and run temporarily on a single lane of the new westbound carriageway. It will then switch to running temporarily on the eastbound carriageway of the new A303 after Steart Hill.
During the closure, access will remain for local residents.
