In 1992, Albert Bridge was rewired and painted in an unusual colour scheme designed to make it more conspicuous in poor visibility, and avoid being damaged by ships.

The width of the river downstream meant that tunnels were the only options for crossings before improvements in technology allowed the construction of high bridges
