Lib Dem County Councillor Kareen Hastrick is leading a campaign to save the popular 346 bus route which serves the Meriden and Tudor estates as well as Watford University Technical College on Colonial Way.
Operator Mullanys are due to withdraw the service on April 1st - a move which would see college students lose their only bus service. The Meriden and Tudor estates are also home to many elderly residents, and those without a car.
"Bus services give elderly residents independence and access to shops, friends and family, and local services. I'm urging Herts County Council to consider supporting residents who live on this route by working to find an alternative operator, or supporting financially by considering the 346 a socially necessary route." said Kareen.
