PLANS FOR a 'third Forth' crossing near the Forth road bridge are unaffected by last week's decision to go ahead with a £120M Forth crossing at Kincardine, the Scottish Executive said.
Environmentalists have demanded that the Kincardine scheme be the last across the Forth. But the Executive said that there was no connection between the two projects.
The existing Kincardine Bridge is the diversion route for HGVs when high winds bar them from the Forth Bridge, but the main purpose of the new crossing is to take 26,000 vehicles a day away from Kincardine at the north end of the old bridge, ' the spokesman said.
'Traffi analyses by FaberMaunsell show that it will have very little effect on traffic on the Forth road bridge.' The 1.2km multispan crossing will be built over sensitive wetlands, which are internationally important winter feeding grounds for numerous species of waterfowl.
Contractors will be allowed to work for only two winters on the project. Ground conditions are challenging, with soft alluviums overlying carboniferous bedrock.
This is riddled with ancient mine workings. The conceptual design, which was prepared by Jacobs Babtie, has 29 spans, with the span over the central shipping lane going up to 70m. There will be only three traffic lanes on the deck, plus a cycleway.
The project goes out to design and build tender shortly, with work due to start next April.
