Workers at the Cross Keys swing bridge at Sutton Bridge, a major route in and out of Lincolnshire, will begin strike action from midnight tonight. The bridge keepers will walk out at one minute past twelve and will not return until a week later.
The action follows a unanimous vote by members of the public service union Unison in favour of industrial action after Lincolnshire County Council proposed pay cuts for the workers.
The bridge carries the A17 over the River Nene and swings open to allow river traffic to pass under it to the port of Wisbech a few times a week.
Road and rail travellers endured another bleak mid-winter morning rush-hour on Friday, with disruption reported in Yorkshire.
Flooded highways and rail lines, over-running engineering work and train staff unavailability all added to the gloom of a dark, wet, late-December journey to work.
In East Yorkshire, Front Street in Burton Fleming was closed due to flooding, while high water levels also meant the closure of part of Mill Lane in Stutton, North Yorkshire.
