Sowerby New Road/Quarry Hill area, Sowerby Bridge
Dates effective: commencing from Tuesday 5th May for the next few months until works completed.
Details: a set of works beginning on Quarry Hill then progressing in stages toward Sowerby Street then Sowerby New Road will begin from the 5th May 2026. When the works are taking place along Quarry Hill and Sowerby Street, traffic will be under the control of temporary lights. However, when the works move onto Sowerby New Road, this will result in its closure.
Implications for school services: diversions are not required during the various stages of the works as full traffic access will be maintained for any services coming off West Street toward Ryburn Valley High School and Sacred Heart Primary School via Sowerby Street, Quarry Hill, Fore Lane and St. Peter's Street.
For those who use the 579 service bus, again, the route along St Peter's Street will be maintained at all stages of the works.
School services that operate via Sowerby New Road may have to divert slightly via Fore Lane and Quarry Hill when Sowerby New Road itself is closed but it is expected that this stage will be during the summer school holidays starting after the 17th July.
For the stages where there are temporary traffic lights, delays should be anticipated however, during the AM and PM peak, these lights will additionally be manually controlled by workers to help with traffic flows.
