jacked underpass below railway
Explanation:
The following text describes your technique. This link includes a nice diagram and a full explanation, but here’s an excerpt:

It will be the first of its kind in the UK. Never before has a tunnel under a motorway been constructed using the box-Jacking technique that Edmund Nuttall is using at Junction 15A of the M1 in Northamptonshire.

The £6m scheme will see a gigantic concrete box constructed next to the motorway and pushed through the embankment to form the tunnel. With several other improvements to the junction, the tunnel will provide a second carriageway for the A43, which is being dualled between Towcester and Northampton.

Although the box-jacking system has been employed before under railway lines, using it beneath a fully-operational motorway represents a different kind of challenge.
So what persuaded the client, the Highways Agency, that this approach made more sense than a conventional cut-and-cover?

Another reference:

Underground structures, such as underpasses, subways or metro stations, can be "jacked" under roads, railways, airfields or buildings. Traditionally underground structures have been installed by open-cut excavation at great cost and disruption. Conventional tunneling is not possible where there is a small amount of cover and the attendant dangers from settlement. Jacked methods avoid such risks and are designed to allow road or rail services to continue uninterrupted during construction.
Tunnel (or Box) Jacking involves the advancement of a site-cast rectangular or other shaped box using high capacity hydraulic jacks. The structure to be installed is constructed, normally in reinforced concrete, on a launch pad at a site adjacent to the installation site. It is then thrust forward horizontally using advance support, open shield and jacking technology with excavation taking place from inside the box. This technique is frequently used where an existing road or rail track is on an embankment and space exists for the structure to be cast at the side. There are variations on this concept using short pre-cast units to form the box.
