ast of the East River. (Plate XV.) The
yard and approaches are designed to avoid grade crossings by opposing
trains. The various general features of the yard and tunnel approaches,
bridge crossings, and street closings, have been described in sufficient
detail by General Raymond in the introductory paper.

Sunnyside Yards]

For convenience in placing the work under contract, a line was drawn 10
ft. west of Thomson Avenue, dividing the work east of that embraced in
the Pearson contract into two parts. The work west of the line was
placed under the immediate direction of George C. Clarke, M. Am. Soc.
C. E., as Resident Engineer, with Naughton Company and Arthur McMullen,
Contractors; Mr. Louis H. Barker was Resident Engineer of the part east
of the dividing line, with the Degnon Realty and Terminal Improvement
Company as the principal contractors. The substructures of the several
bridges in or across the yard were included in these contracts, but the
superstructures were carried out by various bridge companies, and other
minor features were executed by other contractors. More complete
descriptions of the plans and of the execution of the work will be given
by the Resident Engineers.
