Getting here from the airport

From O'Hare

Public transit is from O'Hare to the TTS Chicago office is cheap, fairly quick, and convenient. Blue Line trains run from the airport to downtown 24/7 and take about 50 minutes. The closest stop to the office is Jackson.

From Midway

The smaller of the two Chicago airports, this one is a little closer to downtown-- it's only a 25 minute ride down the CTA Orange Line. The Library/State & Van Buren stops are the closest to the TTS office on your way in, though we recommend getting on at Adams/Wabash on your way out (unless you want to get a tour of the entire Chicago loop). While the Orange Line doesn't run 24/7 like the Blue, it does have regular service between 4:30 a.m. and 1 a.m., covering most reasonable flight departure/arrival times.

Getting around

Public transit

Chicago is extremely accessible by public transportation. Taxis are available but aren't generally necessary for getting around.

To take full advantage of Chicago's CTA trains and buses, we recommend getting a , external,Ventra card, available at any CTA train station. Ventra cards require a $5 deposit, which is refundable after registering, and the card stays valid for 5 years.

Fares from (but not to) either airport cost $5. All other normal fares are $2.25, and include one transfer to another CTA bus or train for $0.25 plus one free additional transfer if made within two hours of boarding.


Garage parking downtown is very expensive. "Early bird" rates start at $18, and normal rates start at $30. Street parking is hard to come by. See above recommendations on public transit.


Chicago is a very walkable city; plenty of hotels, coffee shops, restaurants, and bars are within walking distance of the office. Grant Park and the lakefront (including the lakefront path) are all close by.


Short-term bikes can be rented via , external,Divvy. $15 buys a 24-hour pass with unlimited 3-hour rides.

How do people dress?

Feel free to dress how you like! If you wear a T-shirt and jeans, that's fine. Sometimes folks wear hoodies. If someone has a meeting with agency folks, they may dress up more. We care more that you are comfortable and confident as yourself rather than following someone’s particular rules of formality.

We share our Chicago office space with other GSA folks who trend to dress business casual.

Who can I contact if I have questions about the office space?

TTS no longer has formal operations support for the Chicago office. However, , external, should be able to answer most of your building-related questions. , external,Janie Burmeister may be able to help you with any questions specific to other FAS programs in Chicago and Region 5.
