MOTORISTS were hit with a comical surprise ahead of the visit of a musical superstar this week.

Rod Stewart is set to to visit the University of Bolton Stadium on Friday and traffic bosses found a clever way of warning drivers about the upcoming delays.

Traffic signals across town were seen bearing the phrase, "Wake up Bolton, think I've got something to say to you", in reference to the hit song Maggie May.

General admission gates for the Sailing crooner's gig will open at 5pm, with roads around the Horwich venue set to be busy.

Rod Stewart will take to the stage at approximately 8:30pm with the concert finishing around 10:30pm.

Places with the most congestion are expected to be the surrounding areas of Horwich and the stadium. These include:

• A673 – Bolton Road and Chorley New Road

• B6226 – Chorley Old Road

• A58 – Moss Bank Way and Beaumont Road

• A6 – Blackrod By-pass and Chorley Road

• B5238 – Wigan Road

• A5239 – Dicconson Lane

• B5236 - Church Street

• De Havilland Way

Roads will be busiest between 4pm until 6:30pm before to the concert and from 11pm until midnight afterwards.

Drivers are being advised to allow extra times for journeys.
