PLAN OF ORE YARD IN WEST BREAKWATER 'he modern lake freighter has made this location undesirable owing to. the difficulty of approaching it, there being scarcely clearance enough to enable the larger steamers to make the turn from the main channel into the old riverbed. There was also to be dealt with the problem of swinging the bridge carrying the main traffic of the Lake Shore railway with the result that during busy periods there was always either rail or vessel con- gestion at this point. To obviate these difficulties the Penn- sylvania railway started two years ago to develop its property on the lake front in the west breakwater. The work necessitated a considerable fill and more than a year was spent in reclaiining the land. Approximate- ly 40 acres were reclaimed by filling with slag: and refuse collected on the Cleveland & Pittsburgh division of the Pennsylvania system. In order to facilitate the filling operations a temporary wooden pile trestle filled with rip-rap 'was constructed. The trestle paralleling the shore line for filling, as shown on the general plan herewith, was located a considerable distance from the established harbor line, so as not to interfere with the construction of the dock and ma- chinery foundations. After the cars had been unloaded the material was distributed by the track spreader. Ap- proximately 1,000,000 cu. yds. of filling material was deposited, making the crete piles 30 ft. long unite the dock face with the foundation walls for the rear leg of the wunloaders. Ex- pansion joints are placed at every fifth strut running longitudinally in and the space between the rear wall and the dock face was filled with rip rap stcne varying from shovel to derrick size, a temporary wooden trestle be- ing used from which to handle the stone with a locomotive crane. After the rip rap was brought up to the lake level, the whcle mass' was pumped full of sand by. means of a hydraulic dredge. The dock face protected by wooden piles tied to- gether with a 12 x 12-in. oak waling is 'strip. Back of the rear wall supporting the unloader leg there is a U-shaped ore trough which is carried on rip rap placed immediately back of the wall and filled with sand. The bottom of this trough is protected by steel rails laid so the top of the head is flush with the bottom of the trough. a SS : WO Aa : Oe \ eral em ee ih ta a Re Pie ee) EU AL coetoLes Penna.co.
