The A59 will be closed over summer

The A59 at Brockholes Brow will be closed during the summer as work to stabilise an embankment takes place.

Access to and from the east of Preston will be impacted as the route is a key link to East Lancashire and beyond, as well as travel north or south via the M6 motorway.

Since Mark 2021, one lane has been closed after a small landslip occurred on a steep wooded embankment next to the road, resulting in part of the slope encroaching onto the road.

Monitoring over the past six months has found that the embankment is continuing to move at a rate of around 10 cm a month, with intervention being urgently needed to stabilise it and restore the full width of the road and pavement.

Work is scheduled to begin on Monday 25 July to stop the embankment from moving and mitigate the risk of a bigger landslip occurring if left in its current state.

It is expected to take up to seven weeks, with the A59 at Brockholes Brow needing to be fully closed in both directions for all vehicles for safety and to allow access for the heavy machinery needed.

The scheme has been scheduled during the school holidays when traffic levels are lower to minimise disruption as much as possible, and work will take place 24 hours a day, seven days a week, to minimise the duration of the closure.

Preston City Council owns the embankment where the landslip occurred and has engaged Lancashire County Council as the highways authority for the area to design a solution and carry out the work.

Pedestrian access will be available as normal via the footpath.

What the project involves

  • Installing large sheet metal piles as a retaining structure along a 40-metre length of the embankment
  • Building a 1.2m high retaining wall along the same length.
  • Installing drainage to help protect the embankment from wet weather in the future.
  • Removing excess material from the bottom of the slope to restore the full width of the road and pavement.
  • Landscaping work and planting species native to the existing woodland.
  • Removing the current lane closure and restoring the 40mph speed limit.

While the road is closed the County Council is also planning a range of other routine highway maintenance in the vicinity to avoid the need for further lane closures in future and minimise the overall level of disruption.

Early consultation on the proposed closure has already taken place with emergency services and National Highways, who are responsible for the M6 motorway, and a notice has recently been posted on Lancashire County Council’s website.

Residents in the vicinity are due to receive a letter very shortly, and Preston City Council is currently in the process of visiting local businesses to inform them of the situation.

Additional Routine Highway Maintenance

The list below is additional work currently planned to take place during the Brockholes closure.

  • Cleaning drains and resetting their covers
  • Fixing potholes
  • Renewing high reflectivity road markings
  • Fully replacing six streetlights with new columns and lanterns
  • Renewing the lanterns on other streetlights
  • Replacing the lid on a broken manhole at the bottom of the hill
  • Cleaning road signs
  • Surveying roadside trees and carrying out any maintenance needed

Why the project needs to take place

It’s vital that we carry out this work to safeguard the A59 by stabilising the embankment on Brockholes Brow, and unfortunately, the only way to do this is to fully close the road due to the scale of the work which is needed.

The embankment is still moving towards the road following the landslip which occurred in 2021 and, without this scheme to stabilise it and retain the banking, the situation would keep getting worse until there would be no option but to close the road for safety anyway.

This will clearly be very disruptive, particularly for people who use this route regularly, local businesses, and those who live nearby, and we’re very sorry for the impact this will have on them, however we’ll be making all efforts to minimise this by working around the clock to get the road reopened as soon as we can.

We are in the process of visiting local businesses, and residents in the immediate area should receive a letter in the next day or so. While we can’t do anything about the need to close the road, we will do our best to answer any queries people may have, and respond to any issues people may want to raise.

Signs will be put up on the approaches to Brockholes Brow from early June to inform passing motorists of the closure.

Will diversions be in place?

Signed diversions suitable for all vehicles will be put in place when the work starts:

  • For M6 Eastbound traffic –  via Blackpool Road and Garstang Road
  • For Blackburn Eastbound traffic – via New Hall Lane, London Road, Victoria Road, Church Brow and Cuerdale Lane
  • For Preston Westbound traffic – via Cuerdale Lane, Church Brow, Victoria Road, London Road and New Hall Lane
