THE PROPOSED NORTH RIVER BRIDGE.
A notice of the proposed bridge across the Hudson River, connecting New York city and New Jersey, was given in a recent issue of FIRE AND WATER. On Tuesday week a meeting was held in the Army Building in this city to consider what would be the effect upon navigation of such a structure. The board of engineers of the United States army, consisting of Col. Thomas Lincoln Casey, president; Col. Henry L. Abbott, Col. C. B. Comstock, Lieut. Col. D. C. Houston and Mayor W. R. King, were present. Colonel Casey stated that the bill in Congress for the bridge had been referred to the Secretary of War for an opinion as to the advisability of its passage.
The conditions imposed are that the bridge shall be constructed with a single span over the entire river between the established pier lines, and at an elevation of at least 140 feet in the clear above high water, exclusive of deflections caused by changes of temperature. All railroad companies desiring to use the bridge shall have equal rights and privileges, and shall pay a reasonable compensation to the owners of the bridge. The bridge shall be aq established post-route, for the transmission of mails, troops and munitions of war of the United Slates, and all telegraph companies shall be granted equal privileges.
A letter was read from Gustav Lindenthal, civil engineer, of Pittsburg, Pa., one of the incorporators, who stated that, although the exact location was not yet known, both piers would be within the present pier lines of this State and that of New Jersey. The height of the bridge at the towers would be 140 feet above high water, ami the centre of the span will be 150 feet above high water. As the Brooklyn bridge is only 130 feet at the towers and 135 feet in the centre, the new structure could receive no opposition from navi, gators.
The only dissenting voice at the meeting was that of F. W. Voshing of the Schuyler Steam Towboat line, who stated that he would oppose any bridge that interfered with navigation. It is expected that the great project will be put into practicable shape at no distant date. Mr. Lindenthal has no doubt as to the success of the scheme, and gives it as his opinion that the sum required for construction will be forthcoming. The estimated total cost is $37,000,000, of which $12,000,000 is expected to be spent in buying property rights at approaches.
The proposed stretch of the bridge is from Castle Point, Hoboken, to a point well up from the North River in Fourteenth street, New York Should the work be taken in hand it will prove a tremendous engineering feat, as the bridge will have the longest span and in fact be the biggest suspension bridge in the world. The proposed middle span is 2850 feet in length, and the end spans 1500 feet. The report of the Board of Engineers since made to the Secretary of War makes but trifling changes in the original bill_ It provides that the height above mean high water at the towers shall be 145 feet, and at the centre of the span 155 feet. It also provides that the location, as well as the plan, shall be approved by the Secrerary of War.
