Work to give one of Wales' most historic landmarks its biggest facelift in 65 years has started.
Repair work has started on the Menai Suspension Bridge
Repainting the Menai Bridge, between Bangor and Anglesey, will take eight months and is likely to cause major disruption for motorists.
Thomas Telford's bridge was last painted in the 1990s but because of the many layers of paint it now needs to be completely stripped back to bare metal.
The structure has not had such major work since 1939.
Once it is clear of the old paint, four new layers will be applied to the bridge, which was built in 1826.
At hundreds of feet above the waters of the Menai strait, the job is far from straightforward for the painters.
Drivers wanting to cross the bridge will find a one-way system in place, which will run in different directions at different times of the day.
From 0600 GMT to 1400 GMT, traffic will flow from Anglesey to the mainland.
It will then switch to the opposite direction from 1400 GMT to 0600 GMT the following morning.
The Britannia Bridge will be open in both directions, but it can be subject to closures to lorries especially in high wind.
In the event of an emergency, ambulance and fire services will be able to use the bridge against the direction of traffic flow, which could add to delays.
Full overnight closures will also take place from time to time.
