Celtic's home match against Arsenal clashes with U2's concert at Hampden
Free shuttle buses are being laid on to help fans attending the U2 concert in Glasgow on Tuesday in a bid to ease traffic congestion.
Strathclyde Partnership for Transport (SPT) said 20 buses would run from Buchanan Bus Station to Queens Drive, near Hampden, in the city's south side.
The concert is taking place on the same night as Celtic's Champion's League home match against Arsenal.
Both events will see up to 110,000 at Glasgow two largest stadiums.
SPT said the buses would run from 1700 BST onwards from four dedicated stances at Buchanan Bus Station.
They will return to the city centre from Queen's Drive after the concert.
SPT chair, Alistair Watson, said: "We're in for a very busy night on Tuesday and it's vital that Glasgow's transport runs as efficiently as possible.
"We wanted to ease the strain on the roads and were advised by Strathclyde Police traffic management to focus on the Hampden event for our free bus offer.
"We're glad we can play a small part in keeping Glasgow moving and hope it's a beautiful day."
Strathclyde Police has asked people attending both events to leave early, use public transport where possible and allow plenty of time to reach their destination.
