Stead Lane bridge replacement, UK
Overview: ALE has successfully performed the replacement of the Stead Lane railway bridge near Broadcarr Road, Hoyland, in Barnsley.
Services Required: ALE was contracted to supply trestling for both the existing bridge and new bridge, as well as to remove and install the respective bridges using 12 axle lines of SPMT in a 4 file 6 configuration. The existing bridge weighed 43t, whilst the new bridge weighed 153t.
The trestling for the new bridge allowed it to be erected at low level and then jacked-up to installation height. A separate set of high level trestles for the existing bridge was erected prior to the possession. Once the possession had been completed the existing bridge was jacked-down using ALE’s integrated jacking system, ready for demolition.
The existing bridge comprised of two steel decks and steel parapets on both sides, the parapets also needed to be supported due to the corrosion of the supporting steelwork.
The new deck comprised of two ‘U-decks’ complete with external walkways. As well as the successful removal and installation of the Stead Lane underbridge, ALE carried out the successful replacement of the Nether Lane underbridge over the same weekend.
