Industrial action is set to bring disruption to bus and rail services over the next month starting from Saturday September 30.
Passengers are urged to plan their journeys in advance and check with transport operators for the latest travel advice and revised timetables.
Both Go North East buses and local train services will be affected by the strikes.
The strike at Go North East will run from Saturday 30 September until Friday October 6.
A second Go North East strike is then planned from Saturday October 14 - Friday October 20 inclusive.
Go North East anticipate that very few of its bus services across the North East will run at all. They are therefore advising customers to make alternative travel arrangements.
The main impact in Northumberland will be in the Tyne Valley, where Go North East is the biggest bus operator, but some parts of the south east of the county will also be affected.
Specifically, the following services are involved - the 74, 680, 681, 682, 683, 684, 686, 687, 688, 689, AD122 and X85 in the Tyne Valley as well as the 309, 352 and 353 in the south east.
Given the scale of disruption this would cause, Northumberland County Council has commissioned a number of replacement bus services within the county to make sure school transport is not affected and where possible to provide services for communities where alternative public transport would not be available.

On Saturday September 30 and Wednesday October 4 local train services will also be affected by strikes.
