ASH undertook route selection, scheme design and environmental assessment for the award winning Upper Forth Crossing project

As part of Transport Scotland’s proposals to improve the road network at the Upper Forth Crossing and alleviate traffic congestion around the village of Kincardine in Fife, a new crossing was investigated and ultimately implemented.

ASH was commissioned by Babtie (now Jacobs) in 1994 to assist in the route selection process, alignment appraisals through selection of preferred route and scheme design, environmental assessment, public inquiry and specimen design for both parts of the scheme.

Key Tasks

Route options appraisal

Landscape and visual impact assessment

Landscape mitigation design

Environmental monitoring during construction and maintenance


What we did

As part of the solution to the high volumes of traffic experienced by the village of Kincardine, a new bridge crossing of the Upper Forth upstream of the existing bridge and a link road to bypass Kincardine for north and west bound traffic were proposed. The other part of the solution was the creation of a new eastern link to accommodate eastbound traffic.

An environmental impact assessment (EIA) was undertaken for the preferred route in accordance with guidance from the Scottish Executive as set out in the Design Manual for Roads and Bridges (DMRB) Volume 11.

Since then, ASH has overseen the successful implementation of the landscape elements of both the Eastern Link and the Clackmannanshire Bridge approaches between Bowtrees to the south and Kilbagie in the north.

This included overseeing the implementation of landscape works during construction as well as overseeing the five year maintenance period post-construction.

The Eastern Link five year maintenance period was successfully completed in 2009 and ASH oversaw the maintenance period on the Clackmannanshire Bridge up until 2013.

In 2009 the Clackmannanshire Bridge took the top award in the Project Category at the Saltire Society Engineering Award.
