Upper Forth Crossing Banner

Construction Progress December 2006

Work is progressing on the Upper Forth Crossing with five marine monopile casings installed and concreted. The bridge deck is to be constructed on the north shore, within the former Kincardine Power Station site, and pushed out over the Forth using an incremental launching technique. The first launch is scheduled to take place before Christmas 2006.

The construction of a temporary jetty on the southern shore of the Firth of Forth is almost complete.  The temporary jetty will allow the southern part of section crossing to be constructed without damaging the environmentally sensitive land in the area.

The scheme also includes five other structures, two of which are currently under construction.   These include a bridge over the new Kincardine – Alloa Railway spur at Kilbagie and a farm access underpass for Broadcarse Farm.  These structures are progressing on schedule and foundation work is being carried out.

Phase 1 of the construction of the northern roundabout of the proposed grade-separated junction at Bowtrees is now complete.  This work was carried out in order to change the shape of the existing Bowtrees roundabout from an oval to a circle, in accordance with the final junction design.

A significant amount of the pre-earthworks drainage has now been completed, and it is likely that ground works activity will increase with the next extended period of dry weather.

Old coal mineworkings have been located beneath some parts of the proposed road.  Due to poor and incomplete records, investigative drilling has been required to determine the extent of these workings, as they must be filled with grout to prevent subsidence.  This drilling has been ongoing since mid-September, with the majority of the key areas now completed.  Some drilling and grouting activities are still ongoing on both the northern and southern sides of the estuary.
