Two roads will be closed to all southbound traffic for up to three weeks, starting on Saturday (10 October).
No vehicle will be allowed to use the entire southbound length of Holme Road, Shiptonthorpe and the entire southbound length of Shipton Lane, Holme-on-Spalding Moor, which introduces a northbound one-way system.
The emergency closures are necessary to enable repairs to Yorkshire Water apparatus due to a water leak.
The roads will be closed to all southbound traffic without exception but open to properties directly affected by the closure and emergency services by using the northbound carriageway.
The alternative route for traffic affected by the road closure will be via York Road, Shiptonthorpe, Giant Bradley Way and Holme Road, Market Weighton and Holme Road, Holme-on-Spalding Moor.
