Description of the Chaudière Crossing
The Chaudière Crossing consists of the following structures:
1. The Bronson Channel Span consists of two 15.24 m (50 ft.) spans of precast pre-tensioned hollow core concrete slabs constructed in 1968 with the abutments utilizing the original masonry piers constructed in 1900. The bridge deck was widened in 1978 with the addition of three precast deck units on the west side. A new reinforced concrete deck overlay slab was added in 1993-94.
2. The Ottawa Hydro Electric Power Commission (OHEPC) Channel Span is a single span precast pre-tensioned hollow core concrete deck structure located directly north of the Bronson Channel and is similar in construction. The OHEPC Channnel Span was constructed and widened at the same time as the Bronson Channel Span and also received a new reinforced concrete deck overlay in 1993-94. The roadway width is 12.19 m (40 ft.) with a sidewalk on each side.
3. The Buchanan Channel Span is located directly north of the OHEPC span and consists of a large diameter structural steel plate culvert. The existing culvert structure was installed in 1978 and replaced the original steel trestle structure constructed around 1900. The OHEPC and Buchanan bridges have a total length of approximately 79.25 m. (260 ft.) The roadway width is 12.19 m (40 ft.) with a sidewalk on each side.
4. The Union Bridge is a 73.0 m (239.50 ft.) single span steel through truss spanning the main channel of the Ottawa River. The bridge was constructed in 1919 and received a new reinforced concrete deck slab in 1991. The roadway width is 11.58 m
(38 ft.) with a 1.02 m (3.35 ft.) sidewalk carried outside the truss on the downstream side.
5. Arch No. 1 is a 12 m (39.37 ft.) span stone masonry arch structure spanning a shallow channel of the Ottawa River directly north of the Union Bridge. The arch was constructed circa 1830 as part of the original Chaudière Crossing.
6. Arch No. 3 is a 16 m (52.49 ft.) span stone masonry arch spanning the tailrace from the E.B. Eddy Company's generating plant and is located north of Arch No. 1 and the filled-in Arch No. 2. Arch No. 3 was constructed circa 1830 as part of the original Chaudière Crossing and carries only southbound traffic since the construction of the Hull Causeway structure downstream.
7. The Hull Trestle consists of a steel girder supported on latticed steel columns and concrete foundations. The latticed columns have been encased in concrete. The plate girder is the eastern support for a series of transverse steel beams. These beams protrude from an adjacent concrete retaining wall and concrete spandrel wall of Arch No. 3 which in turn support a reinforced concrete slab widening of the southbound roadway over Arch No. 3 and the fill-in Arch No. 2.
8. The Hull Causeway bridge carries the northbound traffic over the tailrace channel and is located downstream of Arch No. 3. The structure is a four span steel plate girder bridge with a reinforced concrete deck slab and is supported on reinforced concrete abutments, a reinforced concrete pier and two transverse support trusses all founded on bedrock or on caissons drilled into bedrock. The structure was constructed in 1956 and rehabilitated in 1982. The deck was repaired in 1984 and the structure was re-coated in 1995.
9. The Hull Slide Bridge is located north of the E.B. Eddy Company Limited entrance and falls under the jurisdiction of the National Capital Commission (NCC).
