The foundations of the new bridge across the Hackensack riveris under way. and it is expected that the steel work will be placedthis summer. This bridge will consist ot six plate girder deck the existing tunnel 67 ft. to the south. The gradeof the existing tunnel is slightly descending fromwest to east but the grade of the new line will beon an ascent of .73 per cent, from west to east, witha vertical curve of 700 ft. Interposed at the eastapproach and a downgrade thence to the terminalstation. The grade was determined with a view toreduce rock excavation to a minimum without toogreat interference with the track rearrangement westof the hill.
