The typical section on single track grading is 14 ft. in width atsub-grade on fills and 25 ft. in cuts. For double track, with span construction, the fills are 25 ft.,and the cuts 31 ft. wide at sub-grade, the tracks being laid on li-ft, centers. For double track with center pole construction, the fills are30 ft. and the cuts 36 ft. wide at sub-grade, with tracks on 16-ft. centers.

Where required bymunicipal authorities along built up portions of villages, the trackshave been laid in the center of the street but elsewhere everyeffort ha» been made to separate the paths of cars and othervehicles. Wherever possible, the idea has been to lay tracks oneach side of the road leaving a drive-way of 20 to 30 ft. betweeninside rails. Where the highway lies adjacent to the Alton rail-road, and the residences are consequently on one side only, bothtracks have been laid on the opposite side of the road. For the purpose of avoiding heavy grades and curves, private rights of way have been acquired to the extent of four mil tween Lockport and I-emont and of 8,000 ft. near Sag Bridge.
