New 21/21A/X21 leaflet is now available in Middlesbrough Bus Station.
The X22 will connect with the 21 in Peterlee Bus Station. The X22 route from Sunderland will run via Ryhope Green, Dawdon, then head via Seaham Interchange (that's what the timetable says!) then along the A182 then along the A19 coming off at the same slip road as the X10 and head along Burnhope Way (past East Durham College) then into Peterlee Bus Station then onto the 21.
The X22 will only run on school days, out of term time it will operate as the X21.
