Local roads in and around Bolton will be busier than normal as drivers use alternate routes.

The road closures will mean all traffic will need to use alternative routes and there could be congestion on the surrounding roads. The avice is to avoid Crown roundabout, Horwich as well as Tonge Moor Road/Thicketford Road and Crompton Way/Thicketford Road.

Check your quickest route before every journey.

If you are able to, consider travelling by a different mode of transport on the day of the event. Cycling and walking for local and shorter trips may be quicker.


Bolton is well served by rail, with frequent services running to and from the main station in the town centre.
