SEI Summer Field Trip – CTA RPM & Lawrence-Bryn Mawr Modernization

Please mark your calendars for an exciting summer site visit to the Chicago Transit Authority’s (CTA) Red-Purple Modernization (RPM) Program. The tour, led by the Walsh-Fluor Design-Build Team and arranged by Stantec, will focus on station and track improvements at the Lawrence-Bryn Mawr Modernization (LBMM) portion of the RPM. It is expected that the gantry erection of the post-tensioned box girders will be taking place on site the day of the tour. The tour will take place in the adjacent alley.
