The Church of the Brethren General Offices are located at the junction of I-90 and Illinois State Route 25 (Dundee Ave.), at 1451/1505 Dundee Ave. in Elgin.

To reach the offices from O'Hare International Airport, take I-190 east out of the terminal area, soon exiting onto Route 294 (Tri-State Expressway) north, toward Wisconsin. Just after getting on 294, take the exit for I-90 west toward Rockford and follow until you reach the Route 25 exit. The offices are about 25 miles from the airport. Exact change of 30 cents is required to exit at Route 25. (There is also a 40-cent toll en route).

To reach the offices from the west, follow the I-90 tollway to the Route 25 exit. The offices are about 45 miles east of Rockford.

From either direction, turn left at the traffic light at the end of the off-ramp onto Route 25 (Dundee Ave.). The offices are just ahead on the left, with a sign at the driveway entrance (near #67 on the map below).
