Not sure which project you're referring to, but both Gateway and Cross-Harbor are tunnels.

Triborox --- that is one that wanted to know how to cross Hudson. is it the GW bridge?.

The 1929 Regional Plan had something like this crossing the Hudson on the lower level of the then-under-construction GW Bridge.

The current line being advocated by the Regional Plan Association doesn't cross the river. It would instead use the right-of-way of the Hell Gate line from Co-Op City over the bridge as far as Sunnyside Jct., then the freight-only ex-LIRR/NH Bay Ridge Branch across Queens and Brooklyn to Bay Ridge.

The core TriBoroRX project doesn't cross the river. There is one extension proposal to Staten Island that doesn't make a whole lot of sense, but that's a separate project from the Gateway and Cross-Harbor tunnels. The GW bridge is nowhere near where TriBoro is, it's basically on the opposite side of the city. You seem to have some NYC geography mixed up here.

I looked at the interlocking location again that would be required for TriBoro trains to join the HGL, and it could actually be done just south/west of Oak Point yard. Based on the other transit available and the majority of the TriBoroRX stations being in Queens and Brooklyn, I'd estimate that 1/4 to 1/3 of TriBoroRX trains could extend past Northern Blvd in Queens to join the HGL and serve Hunts Point Ave and north. I don't think that the Astoria-Ditmars station is practical given the physical arrangement of the approach to the Hell Gate Bridge.
