A transformer weighing almost 130 tonnes is on the move through Porthmadog.

People are lining the streets to get a glimpse of the transformer as it makes its way to Trawsfynydd.

Rolling road closures are in place.

It is expected to arrive at about 12.30pm, having left Black Rock Sands beach earlier this morning.

It had been due to be delivered to Gwynedd by barge arrive earlier this month, but was postponed following severe weather.

A 330m temporary trackway has been laid on the beach ready for the transformer’s arrival by 80m barge.

A 10m wide corridor has been cordoned off for the trackway with two walkways for pedestrians to cross. Vehicle access to the beach will be via Beach Road.

The route, with rolling road closures, is as follows: depart Black Rock Sands; turn right onto High Street; continue onto Britannia Terrace; continue onto A487; continue onto A470; arrive at Trawsfynydd Substation.
