Page Background

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

national economy.

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

will comprise

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
