•Tower Bridge was built between 1886 and 1894.

•It spans the River Thames, connecting the London boroughs of Tower Hamlets (north side) and Southwark (south side).

•The bridge combines elements of a suspension bridge design with elements of a bascule bridge design. It has two towers linked by two walkways and suspended sections to either side of the towers, stretching towards the banks of the Thames.

•Tower Bridge was designed by Sir Horace Jones, the City Architect.

The central span of the bridge can be raised to allow ships to pass.
