CHICAGO — The CTA board simply permitted contracts for the most important and costliest undertaking in its historical past.
The Pink and Purple Line modernization is predicted to value $2.1 billion.
That modernization undertaking will embrace a Brown Line flyover north of the Belmont station, so Pink and Purple trains do not have to take a seat and wait there.
In the long run, the CTA says this can convey better rush hour service with much less congestion.
The work between Lawrence and Bryn Mawr is being paid for with federal funds and tax increment financing.
Ten buildings in the Lakeview neighborhood have already been demolished with this challenge in mind.
The reconstruction begins within the Fall of 2019.
The Purple, Brown, and Purple Strains will keep up and operating, with some interruptions, until every part is completed in 2025.
An even more costly venture can also be within the works.
The CTA board is approving preliminary work on extending the Purple Line from ninety fifth Road to one hundred and thirtieth Road.
That venture proposal provides as much as $2.three billion.
That preliminary work is for contracts on environmental influence research, which may lead to more federal funding.
The CTA can also be in search of more state capital improvement funds.
The Pink Line is the busiest line within the system, giving seventy four million rides a yr.
