The first permanent structure has now been installed on the Heysham to M6 Link Road.
Road builder Costain said the frame structure of the new Shefferlands Bridge over Halton Road is now in place, meaning Halton Road will be open to traffic again from September 10, three months ahead of schedule.
The frame was transported to the site from Northern Ireland via Heysham Port.
Shefferlands Bridge will carry traffic over Halton Road onto the new Shefferlands roundabout, whilst joining the new Lune West Bridge which connects to Caton Road.
Costain project manager Andrew Langley said that work on the Lune West Bridge is also progressing well, and by mid-October four reinforced concrete pier bases and columns will be completed within newly created shafts.
He said: “We’ll continue constructing the reinforced concrete abutment walls for the remainder of 2014.”
Mr Langley said work is also progressing at ‘Milestone Canal’, the new bridge over Lancaster canal, with the 30m arch beams that will span the canal due on site in November.
The Folly Railway Bridge over the West Coast Mainline now has 6m high abutment walls in place.
Mr Langley said: “The bridge deck will sit on bearings shelves situated at the top of each abutment
“We anticipate completion of the west bearing shelf by late September with the east shelf complete two weeks afterwards.
“Following completion of the abutments there will be a four week fill operation behind each wall that will raise the ground 5m above its current level to provide the fabrication area and suitable crane platform for the erection of the eight 42metre long, 2m deep steel beams using a 1000t crane.
“The beams will be lifted in to position in late November.”
Mr Langley added tat the management teams from both Costain and Network Rail are working hard to resolve scheduling conflicts between the bridge construction operations and track renewals planned for September.
