BRIDGE CROSSING ‘D’ – AERIAL VIEW
Forth Road Bridge
• Corrosion found in main
suspension cables
• approx. 10% loss of strength
(monitoring on-going)
• Bridge may close to:
– heavy vehicles from 2017
– all traffic from 2021.
• Increasing Maintenance
• Dehumidification & Acoustic
Monitoring
• Not practical to repair cables
2005/6
BRIDGE CROSSING ‘D’ – AERIAL VIEW
Replacement
Crossing
• 5 corridors
• 65 options
Cable-stayed bridge
immediately west of
existing FRB
Initial estimate £3.2 to
£4.2 Bn
Ready by end of 2016
2006/7
Feasibility
Study
Transport Planning Objectives
• Maintain cross-Forth transport links for all modes to at least
2006 levels
• Connect to the strategic transport network
• Improve reliability of journey times for all modes of transport
• Increase travel choices and encourage use of alternative types
of transport
• Improve accessibility and social inclusion
• Minimise impacts of maintenance
• Support sustainable development and economic growth
• Minimise the impact on people, the natural environment and the
cultural heritage of the Forth
Programme

Managed Crossing Strategy
• Makes best use of existing
bridge
• Ability to manage future
demand on both bridges
• Provides flexibility and
enhanced operation/
maintenance
BRIDGE CROSSING ‘D’ – AERIAL VIEW
Intelligent Transport
Systems (ITS)
• Extends over full 22km
project corridor
• Variable mandatory speed
limits – manages traffic to
reduce congestion, thus
improves safety &
reduces emissions
• Variable Message Signs –
incident detection and
management provides
high quality driver
information

Forth Replacement
Crossing –
Route Corridor
• Dual 2 & 3 lane m/way
standard road – the M90
• Public transport links
incorporating FRB
• New and improved junctions
Reliable journey times
Improved connections
Increased Safety
Minimise Environmental

Bridge - Specific Features
• Wind shielding
• Wide hardshoulders –
Maintenance, emergencies
& future flexibility
• Use of the main crossing
hard shoulder as a bus
lane when FRB is closed
for high winds

Costs, Funding & Legislation
Costs (December 2008)
• £1.72 - £2.34 billion
• Rescoping of the project
has saved £1.7 bn
• Savings achieved through
less new road construction,
use of existing infrastructure
and narrower bridge (circa
10m)
Funding
• Design & Build contract
• Priority project for
Scottish Government
Legislation
• Parliamentary Bill
• Other forms not viable

Construction Approach to
Project Delivery Governed by the
Code of Construction Practice:
• Overarching aim – least
practicable adverse impact on
communities and environment
• Includes mechanisms to control
construction & impacts, imposes
restrictions on the contractor e.g.
• Working groups
• Traffic routing
• Noise/air quality
• Working hours etc etc
