Holborn Viaduct is a road bridge in London and the name of the street which crosses it (which forms part of the A40 route). It links Holborn, via Holborn Circus, with Newgate Street, in the City of London, England financial district, passing over Farringdon Street and the subterranean River Fleet. The viaduct spans the steep-sided Holborn Hill and the River Fleet valley at a length of 1,400 feet (430 m) and 80 feet (24 m) wide. City surveyor William Haywood was the architect and the engineer was Rowland Mason Ordish.
