The Florenceville bridge

Ralph M. Francis

The paper gives brief details of the design and construction of the Florenceville
bridge which forms a new link in the New Brunswick section of the Trans-Canada
Highway System. The bridge consists of a six-span continuous river crossing 1,296
ft (395 m) long, flanked by eight continuous spans having a total length of 388 ft
(118.26 m) on the north side, and a two-span structure 137 ft (41 .76 m) long on the
south. The six-span river crossing is a continuous prestressed concrete box girder
with end spans of 190 ft (57.91 m) and four interior spans of 219 ft (66.75 m) each.
The roadway consists of two 13-ft (3 .96-m) wide traffic lanes with 5-ft (1 .52-m)
A
wide sidewalks.

new link in the New Brunswick section of the Trans-Canada Highway System was
added with the opening of the Florenceville bridge across the Saint John River in August 1969.

The bridge is built on a 2° 45’ horizontal curve. It consists of a six-span continuous river crossing
1296 ft (395 m) long, flanked by eight continuous spans having a total length of 388 ft (118.26 m)
on the north side and a two-span structure 137 ft (41.76 m) long on the south, Fig 1. To rise above
an existing highway and a high river bank on the south side of the river the bridge has a grade
of 1.32 per cent, Fig 2.
