The viaduct was opened in March 1968 and cost £6 million to build. It was designed to carry three lanes of traffic each way on the top (motorway) deck, but this has since been reduced to two lanes following an EU directive on load bearing. The bridge has since been strengthened, in 1983 and again recently, with work due to finish by Christmas 2005. Although originally designed to carry 6 lanes, during the strengthening work the M1 was reduced to 4 lanes. This arrangement has now been made permernant to allow the third lane in each direction to join from J34 to make the very busy junction safer.

The viaduct is balanced on rollers to counter the vibrations of the wind and traffic, and the route weaves slightly in order to make its way past other buildings. As things currently stand, the Meadowhall Shopping Centre lies in the valley to the west, while to the east is the Blackburn Meadows sewage works. Meadowhall is a large shopping centre located three miles northeast of central Sheffield, England. ...

The viaduct is one of Sheffield's most prominent landmarks, made all the more so by the adjacent pair of cooling towers that were left standing for safety reasons after the demolition of the Blackburn Meadows power station. Both the viaduct and the cooling towers continue to be the subject of local controversy: many criticise the viaduct as unsafe and constantly under repair, and others consider the cooling towers an eye-sore that should be pulled down. The cooling towers in particular have been a major arguing point over the years, and were once only saved from destruction after being chosen as a nesting site by a rare bird. More recently, their iconic status, and the possibly prohibitive costs of demolishing the towers safely, would seem to have rested the debate.
