^ No, there hasn't been a big CTA project completed during her tenure, but the timeline for all CTA projects is much longer than a mayoral term. It takes years to plan a project, do the environmental work, do the engineering, get funding lined up etc before a shovel even hits the ground. Rahm took credit for the Morgan station but that was launched
while Daley was still mayor.
Even now, most of the CTA projects in planning stages were around before MLL took office. Her problem is that she has not introduced any transit priorities of her own - she just doesn't care. Even her signature urban development project - Invest South/West - is just a rebranded version of a program that Rahm started. Now she came out this week calling Chicago a "car city" and promising gas tax relief to drivers, literally starving CTA of revenue for drivers' benefit.
I do give her some credit for hiring Maurice Cox, who has brought very high standards of design into the DPD review process. The archirecture on large proposals now is significantly better than 10 years ago - just look at how the Bally's casino got reshaped from the initial renderings to the latest ones.
