What will the project deliver?

The project will deliver a new, wider road crossing the railway with room for a new footpath and includes re-working and stabilizing the approach banks on either side of the railway. The new structure is 33m long and is constructed of a curved weathering steel composite with a 125-year design life. The increased deck height allows for future rail electrification, with room for overhead line equipment and the use of weathering steel which reduces maintenance by removing the need for painting.

The project also saw the innovative use of Self Propelled Modular Transporters (SMPTs) rather than lifting by cranes. This had three benefits:

  • Wind susceptibility was significantly reduced
  • Precious time was saved reducing the disruption to the rail network
  • A nearby pond was spared from being infilled to accommodate a crane, thereby reducing the environmental impact of the project

Local impact

Local businesses and residents will have better aligned road access and a wider carriageway – meaning increased visibility for drivers and safety benefits due to room available for a pedestrian footpath.

Ilkeston Juniors Football Club will benefit further from the works – the money given to them in exchange for land access is to be used to build new changing facilities.

Interesting facts

  • The old structure was constructed in 1901 and cost £1,216
  • The bridge was lifted in 1951 by three feet due to mining subsidence
  • The existing bridge weighed 425 tonnes (without the parapets) measured when removed
  • The new structure installed was recorded at 525 tonnes
  • The time for the actual possession for replacement took just 20 hours!
  • A time-lapse video of the main works has so far received over 70,000 hits on YouTube and Facebook combined
