I see this old chestnut has raised its head again. A tip I worked out years back was that if you're approaching from the Trefriw side, and you can get past the second set of lights before the amber light comes on, then you will be able to get to the top of the bridge (and thus establish your right to continue) before a vehicle coming from the Llanrwst side.
Historic Llanrwst bridge stand-off between motorists unwilling to back down prompts traffic lights callRegular queues build up as motorists both trying to pass single track bridge from opposite directions refuse to back up

A stand-off between motorists on a historic town’s narrow bridge has sparked calls for a solution to the problem.
Tourist Greg Mape, from Manchester, was visiting North Wales on Tuesday when he spotted an impasse between drivers on the historic Pont Fawr bridge in Llanrwst.
The bridge has stood in the town since the 17th century but is too narrow for two vehicles to pass, causing traffic problems.
Mr Mape said the use of traffic lights could prevent such issues occuring.
He said: “I am not from Llanwrst but often visit the Conwy Valley and often see hold ups around the bridge. Traffic lights at both ends of the bridge might help.”
He said the problem of the narrow road was clear yesterday when motorists had to leave their vehicles in an attempt to clear the route.
Mr Mape added: “Yesterday we were walking by the river and saw traffic stuck on the bridge.
“Several motorists got out of their cars trying to organise a clear route.
“Eventually common sense won, several cars backed down and normality was restored.”
Conwy Council have been approached for comment on whether any measures could be brought in to avoid a repeat of the situation.
