Work is now well underway to rebuild several bridges as part of a project to electrify the railway.
This photograph, taken by reader Mick Ogden, shows where Skew Bridge railway bridge, on Chorley Road, Heath Charnock, previously stood.
It was taken at around 3pm on Saturday and shows the work taking place.
Residents in Adlington took to social media to find out what was happening after hearing the work being carried out on Saturday.
It is one of five bridges in the Chorley area being rebuilt as part of the railway electrification programme.
The clearance under the bridges is being increased to accommodate overhead lines which will power the trains.
Stump Lane, Chorley, is closed until May 12; Rawlinson Lane, Adlington until May 22; and Chorley Road, Heath Charnock until June 19.
Station Road, Blackrod, is shut until May 15 and Grimeford Lane, Blackrod, will be shut from March 2 to June 12. The bridges are closed to traffic, which led to long queues and complaints from drivers in the Adlington area when Chorley Road and Rawlinson Lane were first closed.
