A stretch of the A1 in North Yorkshire will be closed for 34 hours to allow demolition of a road bridge.
Highways England started tearing down Fort Bridge at Catterick a week ago but had to stop due to poor weather.
The road closure starts at junction 56 (Barton) from 20:00 GMT to Scotch Corner and reopens at 06:00 on Monday.
The demolition is part of a £380m upgrade of a 12-mile (19.3km) stretch of the A1 between Leeming Bar and Barton.
The existing dual carriageway is being replaced with a three-lane motorway.
Kneeton Hall Bridge in Richmond will be demolished next weekend with further road closures expected.
Diversions will be in place and drivers are warned there may be delays at peak times.
