The Madison Avenuk Bridgk. -- Next in order is the bridge crossing the Harlem from the terminus of Madison Avenue to One Hundred and Thirty-eighth Street on the Westchester side. As early as October, 1874, the citizens on the Westchester shore petitioned to have a wooden pile-bridge built at that site. After several changes of plans an appropriation of one hundred thousand dollars was made. In June, 1877, a resolution was pa.ssed authorizing the acquisition of the right of way for the approaches to the bridge, and in 1878 the Board of Estimate authorized the issuing of bonds for building the bridge. Soundings were again made so as to determine tlie sites for the piers, but not until February, 1879, did General Greene, the engineer, submit plans and specifications as to soundings and cost. On October 15, 1879, John Beattie was awarded the contract for fifty-nine thousand four hundred and forty-four dollars. A. P. Boiler was called in as consulting engineer and made some suggestions as to change of plan. Beattie complained of the changes. On October 3, 1880, Eugene E. ^IcLean, engineer of construction, was relieved from duty, and E. B. Van Winkle, topographical engineer of the Department of Parks, was placed in temporary charge. A change in the masonwork was again recommended in 1880 and the work was again delayed. Wm. J. McAlpine was then appointed engineer of construction and A. P. Boiler was invited to consult with the board as to the iron superstructure. June 6, 1881, the contract for construction of approaches was awarded to John Mc- Quade for ninety-four thousand six hundred and twenty dollars. The whole cost of the bridge was four hundred and ninety-two thousand two hundred and ninety-five dollars.
