Large new name signs have been erected over the M4 Prince of Wales Bridge as part of work to remove toll booths.
The decision to rename the Second Severn Crossing caused controversy last year.
Dozens of people weighed in on the new signs on social media, with one user branding the new notices “absurdly large”.
Tolls to cross the Severn bridges into Wales were scrapped in December after 52 years.
Highways England, which runs the bridges, confirmed the work had been completed earlier this week.
The new name marked Prince Charles’ 70th birthday and 50 years since his investiture as Prince of Wales.
