Structural Soundness and Repairs
Hammersmith Bridge has long suffered structural problems and has been closed for lengthy periods on several occasions, due to the weight and volume of road traffic now common in inner London, which the bridge was not originally designed to support.
The bridge was refurbished in 1973 with replacement steel trusses, improvements to the mid-span hangers and new deck expansion joints. New deck timbers were installed and surfacing was changed from wooden blocks to coated plywood panels. These panels were subsequently replaced in 1987.
In 1984 the Barnes-side tower bearings failed under a heavy load and had to be replaced.
In February 1997 the bridge was closed to all traffic except buses, bicycles, motorcycles, emergency vehicles and pedestrians to allow further essential repair works. Structural elements of the bridge had been found to be corroded or worn, in particular cross girders and deck surfacing, as well as some areas of masonry.
The bridge re-opened in July 1998 to all road users, subject to a 7.5-tonne weight restriction and with a priority measure in place for buses. Local bus flow was controlled by traffic lights, and routes (such as the number 72) were required to convert from double-decker buses to smaller single-deckers to reduce the load on the bridge.
As part of the renovations following a bomb attack in 2000, the bridge received a complete new paint job restoring it to the original colour scheme of 1887, and new lighting was installed.
The bridge was declared a Grade II* listed structure in 2008, providing protection to preserve its special character from unsympathetic development.

Famous quotes containing the words structural and/or soundness:
“The reader uses his eyes as well as or instead of his ears and is in every way encouraged to take a more abstract view of the language he sees. The written or printed sentence lends itself to structural analysis as the spoken does not because the readers eye can play back and forth over the words, giving him time to divide the sentence into visually appreciated parts and to reflect on the grammatical function.”
—J. David Bolter (b. 1951)
“Not only our future economic soundness but the very soundness of our democratic institutions depends on the determination of our government to give employment to idle men.”
—Franklin D. Roosevelt (18821945)
