Roundabouts on Birmingham’s busy ring road are to be demolished to make way for the new HS2 rail line.

The Curzon Circle and Garrison Circus roundabouts on the Lawley Middleway ring road will be flattened and turned into signalled-controlled junctions under new plans lodged with the city council.

According to the planning application, the changes are required to accommodate the additional traffic generated by the construction of HS2 and the new station in Curzon Street as well as expected traffic movements once it is operational in 2026.

The new HS2 line will be situated between the two roundabouts, running alongside existing railway lines via a higher viaduct in order to cross over a rail line further east.

Curzon Circle links Lawley Middleway with Curzon Street and Vauxhall Road while Garrison Circus connects Garrison Lane, Great Barr Street and Water Lane Middleway.

A statement prepared in support of the application said: "The works involve the re-modelling of the existing Garrison Circus and Curzon Circle roundabouts as four armed, signal-controlled junctions incorporating controlled pedestrian crossing facilities on all approaches.

"The Curzon Circus junction will be a key access into the proposed Curzon Street Station for taxis, service vehicles and for drop-offs to the station."

The main changes will see the carriageway and pavements raised while humps within the roundabouts will be levelled off.
