Project Background &

Scope

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


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

• Delivery of new crossing by 2016:

• Cabinet Decision to proceed end 2007

• Complete feasibility studies 2009

• Complete Design development 2009

• Submit for authorisation 2009

• Authorisation process 2009 - 2010

Managed Crossing Strategy

• Makes best use of existing

bridge

• Ability to manage future

demand on both bridges

• Provides flexibility and

enhanced operation/

maintenance


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

impact

3 Mono Towers, Crossing Stay Cables

BRIDGE CROSSING ‘D’ – AERIAL VIEW BRIDGE CROSSING ‘D’ – AERIAL VIEW

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
