400 Park Blvd, Itasca, IL 60143
The accompanying map shows the Westin Chicago Northwest as a circled asterisk on Park Boulevard, just north of Thorndale Avenue. Thorndale, however, remains badly ripped up, being turned into the access road to the eastward extension of the Elgin-O'Hare Expressway [I-390]. Thorndale is also shown as a major exit off of I-290, just west of the hotel - but that doesn't easily get you to the hotel [whose instructions and map on their website are inaccurate].
Currently, there is no exit from the remains of Thorndale to northbound Park Boulevard - the route we have previously used to get to the hotel. You must reach the hotel coming south on Park Boulevard from Devon Avenue.
If you are coming from O'Hare Airport, or from downtown Chicago, or from I-294 [the Tri-State Expressway, whether coming south from Wisconsin or north from Indiana], take I-90 [the Jane Adams Tollway] westbound. Two exits off I-90 are marked with red arrows: Elmhurst Road [Route 83] and Arlington Heights Road [a more winding route]. If you take the southbound Elmhurst Road exit, Devon Avenue is about six stoplights south, the first road after you cross the railroad tracks; turn right on Devon, head west to Park Boulevard, then make a left turn onto Park Boulevard [you will see the hotel]. This route is marked with a red-and-yellow line.
If you approach the hotel using I-290 [which joins I-355 to the south], do not take the Thorndale Exit. Instead, exit eastward at Biesterfield Road [about a mile north], head east to Arlington Heights Road and turn right [south]. This connects you to Devon Avenue; turn right on Devon, head west to Park Boulevard, then make a left turn onto Park Boulevard. This route is marked with a green line. [You could also exit westbound at Biesterfield; just west of the expressway, make a left onto Rohlwing Road, then a quick left onto Devon - and, just over the expressway, the first light is Park Ave, where you make a right turn to the hotel].
The new extension of I-390 eastward from the junction with I-290 is an all-electronic tollway - with VERY HIGH toll rates, but no toll booths or cash boxes. If you do not have a transponder for use with the Illinois I-PASS system, you will be flagged for an unpaid toll, to be dealt with as follows: "Drivers with an unpaid toll should make note of the toll collection location by identifying the toll plaza name, route or nearest milepost - then go online to make payment at www.illinoistollway.com, or pay by mail within the "7-day grace period". While an exit from I-390 to Park Ave is planned, it is not now constructed - so you will have to exit further east, then wind your way back west to the hotel on poorly-marked roadways under construction.
From downtown Chicago, a Milwaukee District West Metra train will take you to the transit stop near Irving Park Road, shown by the notation "Downtown Itasca." If you call the hotel [630-773-4000], they will send a shuttle for you. If you want to take a taxi from the station to the hotel, the taxi should head north on Arlington Heights Road, then left onto Devon and left onto Park.
