Bridge Documentation

This is an unusually configured bridge. The longest span on this bridge is estimated at 185 feet in length, but it is not the main span. The 2nd span from the west is in fact designed as a swing span, although it appears it has not operated for boats in a very long time, and no surviving mechanical elements appear to remain at all. The swing span is estimated at 155 foot span. The design of the swing span very closely resembles the design of all the other fixed truss spans, however the diagonals assume a Warren truss configuration, and there is a unique, heavy vertical member over the swing pier. Otherwise the design details are quite similar. The fixed truss spans are not all the same length either. Some of the fixed spans are closer to 155 feet in span length.


MacKinnon Steel Company was originally founded by George MacKinnon, shown below.

The following was part of an advertisement for share offerings in the MacKinnon Steel Company, published in the Montrael Gazette, December 14, 1928:

The Company, which has been incorporated under the laws of the Dominion of Canada in 1928, has acquired as a going concern, the assets and undertakings of the MacKinnon Steel Company, Limited. The MacKinnon Steel Company, Limited, and its predecessor, MacKinnon, Holmes & Company, Limited, have been in suc cessful operation for the past nineteen years. Throughout most of this time during which it has been operated and controlled as a Family concern, a large proportion of the earnings have been used on improving and enlarging the plant. The plant consists of a modern structural steel plant situated in Sherbrooke, Quebec. The buildings are all steel frame with brick walls and the site which has connections with both the Canadian Pacific and Canadian National Railways, has an area of about six acres. The business of the Company has been chiefly the fabrication and erection of steel frames for buildings, steel bridges and plate work. The MacKinnon Steel Company has successfully carried out contracts for bridge and structural steel work for the Quebec Government, Canadian National Railways, Canadian Pacific Railway, Fraser Companies Limited, Brompton Pulp and Paper Company, Limited, Asbestos Corporation, Limited, Shawinigan Chemicals, Limited, and many others. The plant is capable of double its current output and provision has been made in the present financing to handle the increased production. The fabrication of tanks and various other plate products for which there is such a large demand at the present time will be added to the Company's production. ASSETS: The Company has purchased the real estate, buildings, machinery, and contracts of the predecessor Company for a sum of $450,000. An appraisal made by the Canadian Appraisal Company, Limited, as of October 29th, 1928 values the real estate and replacement cost of the buildings, machinery and equipment at $469,044 and the depreciated value at $389,142. The Balance Sheet, certified by Messrs. Price, Waterhouse and Company, Chartered Accountants', as of October 20th, 1928, after giving effect to the present financing shows net current assets of $227,247, making total net assets of $677,247. The current assets are over four times the current liabilities. EARNINGS: The net earnings of the MacKinnon Steel Company, Limited, as certified by Messrs. Price, Waterhouse and Company, Chartered Accountants, after giving effect to the present financing for the year ending July 31st, 1928, after provision for depreciation and income tax amounted to $90,798. As applied to MacKinnon Steel Corporation, Limited, this is over twice the Preferred dividend requirements; and after payment of Preferred dividends, $4.00 a share on the Common stock. For the period from August lst 1928 to October 20th 1928, the net earnings after depreciation and income tax have been at approximately the same rate as the last fiscal year. CONVERSION PRIVILEGE Holders of the, Preferred shares have the right, at their option, to convert each share of Preferred into two shares of no par value Common stock of the Company and the calling of such Preferred shares for redemption shall not extinguish their right of conversion until the expiration of the thirty days redemption notice. MANAGIMENT The management of MacKinnon Steel Corporation, Limited, will continue in the hands of those who have been associated with the successful operation of the predecessor company for many years. It is confidently expected that the new interests which have come into the business rn a substantial way will materially supplement operating conditions, and not only assure the Company a continuance of the current rate of production, but also the increased capacity which the plant is capable of handling.
