Following the concept design further studies were
carried out for all the navigation span bridges and
marine viaducts. Several alternatives were considered
for Jizhou Bridge but finally the original concept was
retained, Figure 45 a, b, c.
As the concept designer for Jizhou Bridge it was
particularly pleasing that the committee thought it fit
to retain the original concept. It was also a lesson in
how to manage the expectations of people with
diverse cultural concepts of aesthetics.

H. Queensferry Crossing Scotland (2007-2017)
As the concept designer for Queensferry Crossing I
consider myself lucky to have been involved in the
longest bridge of its type in the world which
incorporates some major firsts in bridge design and
construction.
In 2008 Arup in joint venture with Jacobs were
appointed by Transport Scotland to undertake the
concept and illustrative design of the bridge which
was opened to traffic in September 2017.
The bridge carries a dual 2-lane with hard shoulder
motorway and is in a World Heritage site and adjacent
to the world famous Forth Railway Cantilever Bridge
and the 1960s Forth Road Suspension Bridge and the
alignment is upstream of both of them where it
crosses Beamer Rock which is a volcanic extrusion,
Figure 46.
