A1 in North Yorkshire closed for bridge demolition
The A1 in North Yorkshire will be closed in both directions for 34 hours from 20:00 GMT on Saturday to enable a road bridge to be demolished.
The Highways Agency said the closure was from junction 51 (Leeming Bar) to Scotch Corner until 06:00 on Monday.
The demolition of Fort Bridge, Catterick, is part of the £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.
The Highways Agency said the closure was "essential". It said there would be diversions, but warned drivers of delays at peak times.
