Travel Information

Getting to UIC: The workshop will be held in the UIC Math Department, which is located in the Science and Engineering offices building (SEO, 851 S Morgan St, Chicago, IL 60607).  Signs with instructions on where to go will be throughout in the building, but you can also come to Wenliang Zhang's office (SEO 413) looking for more information as well.


  • By car: UIC is easily accessible by car, and is located just off of either the 90/94 or 290 interstates.


  • Parking: If you are driving into UIC, it's best to park at the Halsted Parking Structure at the NE corner of the Taylor and Halsted intersection.  You will have take a ticket for the parking garage; if we know in advance you will be parking there, you can bring your ticket in to the workshop and we can validate it to cover the cost.  Note that in/out privileges are not included in the validation.  Also note that the parking at the Crown Plaza is far more expensive, and should be avoided if possible. It is recommended that you plan to park your car in the Halsted Parking Structure for the weekend instead.


  • By train/bus:  UIC is also close to Chicago's Union Station with convenient Amtrak trains / Megabus routes to many locations in the region.  The Greyhound station is also very close by, and an easy walk to UIC.


  • By air: Chicago has two major airports, O'Hare (ORD) and Midway (MDW), and it is easy to get to UIC from either one (many travel sites will let you look for both simultaneously using the airport code CHI).


If you are flying into O'Hare, you can take a Blue Line train into the city (towards the loop or Forest Park) which stops right next to the UIC campus (at the UIC/Halsted station) and in walking distance (half a mile) to the Crown Plaza hotel.


If you are flying into Midway, you can take an Orange Line train into the city (towards the loop), which will take you within walking distance of the Crown Plaza hotel (about a quarter of a mile from the Washington/Wells station) or allow you to transfer to the Blue Line (at the Harold Washington Library station) which stops right next to the UIC campus (at the UIC/Halsted station).  Another good option is to take the Orange Line into the loop (e.g. Harold Washington Library station) and then take a short cab ride to UIC or the Crown Plaza.
