The bridge was designed using prestressed precast
concrete box beams, four per side, each spanning ninety
feet, bearing on cast-in-place abutments.
Huron Line serves
as the main artery of business travel between Canada and
the United States, therefore, the bridge had to be
aesthetically pleasing. To help accomplish this
there is a large area on the bridge set aside for the
inclusion of landscaping, trees and a shrubbery.
The Prestressed Group helped incorporate a precast
planter into the design that would accommodate two or
three full-grown trees, as well as other small bushes
and flowers. The manufacturing of this piece was
accomplished with a custom built form and two separate
casts of concrete totalling over eleven cubic metres.
Since the highway
is the only approach to an international border and is
extremely busy, the planter and box beams were installed
at night in order to cause minimal disruption of traffic
flow. |
