"The Quebec, Monteal, Ottawa and Occidental Railway
commissioned the Chaudiere Bridge at Ottawa. It was a through
bridge with a single track and thirteen spans, seven of which were on
the other side of an island from the six shown. The railroad
became part of the Canadian Pacific system. From the 1888

caption was not correct. By the time the bridge contract was
awarded,
the Quebec Government had already taken over the QMO&O and it was
that government that issued the tender and contracted for the bridge.
The cost was met by Quebec, with $5000 extra from the City of
Montreal, which wanted to ensure that the eastern terminal of the
Canadian Pacific Railway would be in Montreal, rather than in Toronto.
It was the Quebec government which sold the QMO&O and the bridge,
at a loss, to the CPR on 1 May 1882.
The Prince of Wales Bridge was the first railway bridge across the Ottawa River. It was built to the design of C. Schaler Smith, the consulting engineer, for the Québec, Montréal, Ottawa and Occidental Railway when it extended across the Ottawa River from Hull to Chaudiere. The piers, embankments and masonry work were built by H.J. Beemer who bid $112,875.10. Work commencing in May 1879 and this phase was completed on 12 October 1880. The Phoenix Bridge Company completed the erection very quickly as it was ready for testing on 13 December 1880. In effect, this is two bridges located either side of Lemieux Island, just above the Chaudiere Falls. The original bridge consisted of 11 spans of 165 ft., one span of 145 ft. and one span of 265 ft. The substructure consisted of stone piers founded on rock, which is located at no great distance below the water level except the longest span where there is about 30 ft. of water. The original Phoenix pin and eye-bar spans carried the traffic into the CPR period but the decision was taken in 1926 to replace the original superstructure with spans of stiff rivetted construction capable of carrying heavier loads. The substructure was found to be in excellent condition and with minor repairs and changes to accommodate the new pier members, it was continued in service to carry the heavier locomotive loadings. The contractor for the fabrication and erection of the steel work for the new bridge was the Dominion Bridge Company, Montreal. The erection work, extending over 8 months, was completed February 28, 1927 and was carried out without mishap or delay to trains. |
2.3 St. L&O Rideau River Bridge (the White Bridge).
The original bridge was inspected by Thomas Ridout of the Department of Railways and Canals on 15 July 1882, it being the intention of the St. Lawrence and Ottawa to open this line, which had been build eleven years earlier, to passenger traffic. The Inspector found:
"All the bridges are of timber - the principal one being a Howe truss deck bridge over the Rideau River composed of three spans of 100 ft each resting on masonry abutments and piers. This having been erected in 1871, is now eleven years old and has lasted the general life of unpainted and unprotected timber bridges. Upon a careful examination by boring I found that many members of the chords and floor beams were in a bad state of decay and from other indications as well I have no hesitation in stating that I consider this structure in an unsafe condition. Carpenters are now engaged in putting in new oak prism blocks and screwing the trusses up, but the time has passed for mere repairs as the strength of every portion of the bridge is much reduced from age and therefore cannot be relied upon. In my opinion an entirely new structure is required."
This bridge was rebuilt with four through truss girder spans with a total length of 303' 4". Photographs are to be found in the Ballantyne collection which is in the National Archives. At this time it was known as the "White Bridge".
On 19 November 1912 BRC order 18075 authorized the CPR to reconstruct the bridge. Details are shown in Order in Council PC 1912-2645 of 28 September 1912. The work consisted of replacement of the three 100' through spans by one 100' deck lattice span, two 60' deck plate girder spans and two 30' deck plate girder spans. As the bridge was in the immediate vicinity of the locks at Hogs Back on the Rideau Canal, the CPR was required to keep clear of ice the two short openings which will be left at the north and south ends of the bridge which might become jammed by ice during the spring freshets each year.This work was completed and authority to operate over the reconstructed structure was obtained through order 21531 of 21 March 1914. The existing 100' central span of the bridge was originally located at mile 88.2 on the Sherbrooke Subdivision and was presumably installed during the 1912-14 reconstruction.
On 3 May 1913, the Ottawa Journal reported as follows:
The new C.P.R. bridge over the Rideau river a mile below Hog's Back has been practically completed. It is a low black bridge and the piers used for the former structure have been used.
On 26 January 1967 CPR were authorized to reconstruct the north end of the bridge (BTC order 123335). On 15 January 1968 CTC order R-1480 authorized the CPR to "operate over the northerly span of the Rideau River bridge which crosses over the Campus Road of Carleton University."
The original mileage of the bridge is shown as m. 2.64 of the Prescott sub, this became m. 2.51, presumably with the change in measurement from Broad Street to Ottawa West and finally it became m. 2.38 of the Ellwood sub.

2.4 St. L&O Rideau Canal Bridge at Dows Lake.
The St. Lawrence and Ottawa Railway was authorized to construct a swing bridge across the Rideau Canal by order in council
PC 1871-523 of 12 January 1871. This was in connection with the proposed extension to the Ottawa River. It was approved on the following conditions:
(1) The Company shall construct and maintain abutments and piers and all works connected with the bridge and form a channel of sufficient width and depth on both sides of the centre pier and grade a towing path on both sides of the Canal across the space occupied by the bridge at its sole cost and expense;
(2) The Company shall constantly keep men at the bridge to open it for the passage of vessels during the season of navigation and that such arrangements shall be made to ensure no delay or detention to vessels in consequence of the bridge or any of the works connected with it;
(3) The Company shall be held strictly responsible for any damage that may arise to vessels through obstruction of the Canal whether through inattention or neglect on the part of the company or its servants - improper maintenance of the works, accident or otherwise.On July 15 1881 the bridge was inspected by Thomas Ridout for the Department of Railways and Canals in connection with the application by the railway to commence carrying passengers. The government inspector wrote:
"The next bridge of importance is that over the Rideau canal, a swing bridge of two openings 40 feet each, resting on timber crib abutments and centre pier. The timber of this was also tested with an auger which shewed that considerable decay existed, particularly in the centre member of the chords, which were completely rotten. The floor beams are becoming soft and many of the oak timbers of the turntable are decaying. The cribs are also in a bad condition and have settled to a great extent - a few pieces have been added to bring them up to level. This bridge should also be replaced."
The Ottawa Free Press of 27 March 1886 noted:
"A new wooden swing bridge is being erected on the line of the St. L. & O. railway over the Rideau canal. Quite a large number of builders are engaged in the work."
Following a further rebuilding, the CPR was authorized to use the bridge by BRC order 12053 of 21 November1910 and further work was carried out in 1914. Orders 21062 of 22 December1913 and 22920 of 26 November1914.
Order in Council PC 1916-743 of 4 April 1916 describes a more detailed reconstruction:
"Under date of 3 March 1871 a license was granted to the St. Lawrence and Ottawa Railway, their successors, heirs and assigns, to build, maintain and occupy for the purposes of the Company, a swing bridge over the Rideau Canal at the entrance to the cut on the southerly side of Dow's Swamp.
The Canadian Pacific Railway, successors to the St. Lawrence and Ottawa, now desire to construct a new substructure replacing the present old timber and cribs with a permanent structure. Approves a plan showing the proposed work."
The detailed work was authorized by BRC order 24969 of 10 May 1916.An interlocking plant was installed under authority of BRC order 30633 of 9 February 1921."CPR authorized to construct an interlocking plant at bridge No. 1.9 over the Rideau Canal on condition that when a distant signal is at "stop", all trains must come to a full stop at that signal and then proceed to the home signal and there be governed by the rules covering the operation of interlocked signals."
Changes were made to the interlocking under BTC order 72440 of 19 May 1949 and 72725 of 11 July 1949. Trains were limited to10 mph.but 30633 was amended to remove the requirement to come to a stop when the distant signal was at stop.
The Rideau Canal swing bridge was taken out of service with the opening to traffic of the Dows Lake tunnel on 3 May 1967.
This bridge was built by the M&O and opened on 17 July 1898. The M&O had already been leased by the CPR in perpetuity on 15 November 1892, so this was really a CPR bridge. It is an 8-span through steel girder bridge,each side plate girders being 65 feet x 74" x 15",on a slight curve. There are masonry abutments. The curved ends of the bridge at the east end have faintly visible raised lettering in the steel, reading "Carnegie." meaning that the bridge was produced by Andrew Carnegie's Carnegie Steel Company, formed on 1 July 1892. The steel in this bridge is original.
The bridge has been converted into a bicycle path. A new utilitarian deck will (1999) sit above the steel cross beams. A second handrail will be added to raise the present one (also not original), for bicyle safety which will change the external appearance of the bridge somewhat.
This bridge was the first bridge across the Rideau River and was opened when the B&P extended into Sussex Street in January 1855. It consisted of four 96' 11" through truss spans with masonry piers and crib abutments. The crib abutments were changed to concrete by authority of BRC order 33470 of 23 March 1923. There was a second 53' 10 1/2" Pl girder span bridge with crib abutments. The bridges were taken out after the abandonment of the Sussex Street subdivision in April 1964. The three piers in the main river can be seen today, although one can only be seen at low water.
