A557 Watkinson Way has been closed to traffic by Halton Council, causing disruption on M62 Junction 7.
Elsewhere, an electrical fault has resulted in a loss of power to traffic lights at Parr Street and Ashcroft Street, opposite Parr Swimming and Fitness Centre. The Electricity Board is working quickly to restore power.
Motorists are advised to avoid both areas and use alternative routes.
Further updates will follow.
UPDATE: Both issues have now been resolved.
