When the Hudson and Manhattan Railroad was laying out where its tracks and stations would go, the plans included a connection to the East Side via Astor Place and then on to Grand Central Station. This segment of the lines was never built, although a short stub of maybe 50 feet was built just east of the 9th Street Station.
Now comes the Second Avenue Subway with construction contracts about to be
awarded. How about completing Mr. McAdoo's plans and building the extension out to Astor Place with transfers to the number 6 line and then Second Avenue?
That's a pretty short line from 6th Avenue to 4th Avenue and 2nd Avenue. Even the Port Authority should be able to manage a project like that.
