One of the largest infrastructure
projects in North America, due for
completion in 2019.
The Champlain Bridge Corridor Project highlights Arup’s
use of global expertise to bring an innovative approach
to the procurement of a multi-billion dollar infrastruc-
ture project in Canada.
Since 2012, Arup has been providing expert tech-
nical advice to the Government of Canada to facilitate
the replacement of the 3.4 km-long Champlain Bridge
over the St Lawrence River and Seaway and 4 km of
congested urban highway. It is one of the busiest corri-
dors in Canada and hence is vital to both the local and
When the condition of the existing bridge deterio-
rated in the fall 2013, Arup accepted the challenge of
developing the design and technical requirement for
this complex $4.239bn (CDN) PPP project so that the
RFQ and RFP could be released within nine months.
The challenge was compounded by the objective to
deliver a high quality architectural solution, whilst achiev-
ing a bridge with a 125-year design life.
The curved alignment and sculptural piers create an
instantly recognisable shore-to-shore design with the
elegant main tower and its harp of cables adding a
unique accent to the bridge.
The design accommodates future public transport
plans by retaining the flexibility to run buses or a light
rail train on a central transit corridor.
The total length of the bridge is 3.4 kilometres and
60,000 metric tons of steel, 1.3 million bolts and
over 250 m³ of concrete.
The design lifespan is 125 years and is due for delivery
in December 2018.
Building any bridge is a highly complex undertaking.
Given the very tight deadline, the contractor, Signature
on the Saint-Laurent , has opted to work on several
aspects at the same time.
The contractors, therefore, built three large tempo-
rary jetties to enable work on various sections simulta-
neously to meet the delivery on time.
This strategy enables the contractors to maximize
on-site prefabrication and pre-assembly of concrete and
steel parts as well as their subsequent assembly
