The Red and Purple Modernization (RPM) Phase One Project is the largest capital project in CTA history, consisting of a new bypass structure just north of the Belmont station, a complete rebuild of the Lawrence, Argyle, Berwyn and Bryn Mawr stations and the installation of a new signal system between Howard and Belmont.
