"My daughter received an email from TfL stating the following...
I am writing to let you there are changes to bus route S3 until Saturday 23 August, in the Worcester Park area. This is due to work on Central Road between Green Lane and Station Approach on behalf of UK Power Networks, Thames Water, Network Rail and Kingston upon Thames Council.
During this time, services will be as follows:
• An hourly service will run between Malden Manor and Worcester Park
• One in three buses towards Malden Manor will be diverted and will not serve Langley Avenue, Browning Avenue and Green Lane
All other buses towards Malden Manor will be curtailed at Green Lane; the last stop will be on Longfellow Road."
