Route No. 27, Connection with Mott Avenue and 149th Street. -An agreement was entered into on March 12, 1917, between The City of New York, acting by the Public Service Commission, and the Interborough Rapid Transit Company, whereby the Interborough Rapid Transit Company was to perform such construction as was necessary to complete the connection between the Lexington Avenue branch of the Seventh Avenue-Lexington Avenue subway and the Manhattan-Broadway Rapid Transit Railroad at 149th street, between Gerard and Mott avenues.

All working drawings are made and shop drawings checked for this work.

Extension of Mott Avenue Station Platforms and Connection to New York Central Railroad Station. On November 6, 1916, an agreement was made between The City of New York, acting by the Public Service Commission, the Interborough Rapid Transit Company and the New York Central Railroad Company, whereby the Interborough Rapid Transit Company was to extend the Mott Avenue platforms to the east on account of the construction of connections between the First Subway and the new Lexington Avenue subway, and to provide a means of passage between the Mott Avenue station of the First Subway and the proposed New York Central station at 149 th street.

All construction drawings for this work are complete. Construction: Route No. 43, Section No. 1.- Excavation in both earth and rock has been practically completed. Work of this character was carried on within the limits of the site of the former Grand Union Hotel and under both Park avenue and 42d street; the latter excavation being beneath decking. The only excavation remaining is that required for the ventilation chamber to be built on 42d street between Park and Lexington avenues.

The difficult task of reconstructing the portions of the existing Manhattan-Bronx Rapid Transit Railroad at the points where the new railroad connects with the old, was successfully accomplished during the year. The Diagonal Station structure, with

its mezzanines and connections to the Grand Central stations of the Manhattan-Bronx subway and the Queensboro subway, has been practically completed. The connections include a passageway which joins the platforms of the Diagonal Station with those of the Grand Central station of the Queensboro subway. As the construction of this passageway was not contemplated by the original contract, a special agreement for its construction was entered into.

About 85 per cent of the work of constructing the new shuttle tracks for the trains which are to be operated between the Grand Central station and the Times Square station is complete.

Subsurface restoration has been in progress, but considerable work of this kind remains to be done. Some backfill has been placed and temporary pavements laid over same.
