A second plaque with the name of engineer Isambard Kingdom Brunel is being unveiled on the bridge between Devon and Cornwall.
Brunel died four months after the Royal Albert Bridge was opened
The ceremony on the Royal Albert Bridge in Saltash will be attended by the town's mayor and members of the region's institute of civil engineers.
A plaque with "I K Brunel - Engineer - 1859" was unveiled at a ceremony on the Devon side in Plymouth last month.
An identical plaque in Cornwall was previously hidden by access gantries.
Network Rail has now moved the tribute to Brunel to celebrate the 200th anniversary of his birth.
Brunel is regarded as one of Britain's finest engineers and the Royal Albert Bridge over the Tamar is recognised as one of his greatest designs.
He died just four months after the bridge was opened.
