Around 4km of connecting roads will be built to tie the new crossing into the main trunk road network.
To the south of the bridge, a new motorway standard road will link the crossing to the A90 and M9 making use of the recently completed M9 Spur.
To the north, a new motorway will connect the bridge to the A90/M90, incorporating junction enhancements at Admiralty and Ferrytoll and road widening between those junctions.
State-of-the-art Intelligent Transport System technology will be used along the full length of the scheme from the M90 Halbeath Junction over the bridge to the M9. This will improve traffic flow, reduce congestion and improve road safety.
By maximising the use of the existing road network, the connecting roads will result in less impact on the environment, properties and communities.
The connecting roads strategy has been one of the major pieces of work undertaken by the Forth Replacement Crossing team and the selected design is the result of a lengthy development process that included extensive consultation with the public and stakeholders.
More than 2,200 people attended exhibitions at a range of venues in Fife, Edinburgh and West Lothian in January 2009 and we received just over 200 responses to the consultation. Comments relating to the key road junctions were factored into the design process to finalise the location and geometry of the junctions for South Queensferry and at Ferrytoll. These have also been discussed with representatives of the relevant community councils and local authorities.
