The car park at Poulton station is set to re-open on Friday.
The facility was closed to allow Network Rail to carry out drainage work around the station ahead of the electrification of the route between Blackpool and Preston.
Works on the line continue this weekend with rail replacement buses in operation.
The weekend closures are to allow major works to take place at a number of locations.

At Poulton, the track is being lowered to allow the installation of overhead electrical cables. At Salwick, the track is being replaced and foundations for the gantries which will support the power lines are being installed.
Network Rail has already put more than 40 foundations in place along the route.
The line will close completely for four and a half months on November 11 to allow the multi-million pound upgrade to be completed.
The work includes extensive remodelling of the railway at Kirkham, where an extra platform will be built and Blackpool North where platforms are being lengthened and straightened.
The upgrade will allow electric trains to operate into Blackpool North for the first time from the end of May next year.
