As part of the HS2 project, Euston will be remodelled to integrate with the current classic rail station, and improved connections to Euston Square tube station, which serves the Circle, Hammersmith & City, and Metropolitan lines will be provided. Euston will also be better connected with HS1's terminus at St Pancras, including a proposed station on Crossrail 2 under the British Library. St Pancras's own links with King's Cross station will effectively create a "mega-station" along the Euston Road from Euston Square in the west to King's Cross St Pancras in the east.
