Members of the Public and Commercial Services union (PCS) at National Highways in operational roles on roads and in control centres will take part in a series of staggered strikes from Friday to January 7.
National Highways, which is responsible for managing England’s motorways and major A-roads, does not expect he action to have a significant impact on traffic as only around 8% of its frontline workforce are PCS members.
But many of its routes already suffer from severe congestion during the Christmas getaway.

Border Force workers are set to strike on December 23.
PCS members at Heathrow, Gatwick, Manchester, Birmingham, Cardiff and Glasgow airports will walk out.
Extensive passport checks are only carried out on arrival but long queues could see passengers held on planes after they land, causing delays to departures.
Airlines have been urged by Border Force to cancel up to 30% of flights on strike days to prevent chaos at airports.
But easyJet said it intends to run its full schedule as “we want to take our customers on their planned trips at this important time of year”.
The only sea port affected by the Border Force strikes is Newhaven, East Sussex, from where ferry services operate to and from Dieppe, France.
A walkout in Kent affecting the Port of Dover and Eurotunnel would likely cause severe disruption.
Eurostar will run a revised timetable between Tuesday and Saturday due to the reduction in running hours on rail lines caused by the RMT strikes at Network Rail.
The operator is not affected by the Border Force walkout, and does not anticipate its services will be affected when RMT members employed as security staff by private contractor Mitie at London St Pancras International go on strike over the next fortnight.
