YELLOW Buses have been forced to change two of their services as a result of the A338 delays.

The bus company has made the temporary changes to the 737 Jet Bus airport service and the 111 school service.

They will both have to leave up to 20 minutes earlier so they can arrive at the advertised time.

Simon Newport, head of commercial, said: “Due to the heavy congestion caused by the roadworks we have brought departure times forward so we can still deliver passengers on time.

“We expect to return to the previous times when the works are completed. All the details are on our website.”

The changes take effect from Monday.

It comes as work on Hunger Hill in Poole is due to start on Monday, with warnings already issued to motorists over expected delays.

MoreBus have also suffered heavy delays as a result of the works.
