February 2026 Update - Castle Road, Ellon

Further works are scheduled on Castle Road in Ellon to facilitate the connection of the new trunk main to the existing water network. 

Starting Monday, 16 February, three-way traffic lights will be implemented at the junction of Castle Road and Meadows Way for approximately four weeks.

We will have advanced signage up on Castle Road to advise commuters of the lights.

We appreciate the patience and understanding of road users and residents. We recognise that Castle Road was closed a few months ago, and we thank you again for your cooperation as we move forward with this essential work.
