Directions to Robert Allerton Park and Conference Center

September 2012 – Bridge Now Open!

In September 2012, the bridge across the Sangamon River in Allerton Park reopened to vehicle traffic. Unfortunately, the new map provided by the University of Illinois is smaller and less detailed than the old one and the directions are now gone from the Allerton Website.

Map to Allerton


  1. Turn off Interstate 72 at Monticello exit 164 onto Bridge Street and drive south towards Monticello. Turn right (west) at the first crossroads which will be old Route 47.
  2. Travel approximately 2 miles west and turn left (south) onto County Road 6.25E.
  3. At the stop sign, turn right (west) onto County Farm Road.
  4. Turn left (south) onto the first road you come to, which will be Old Timber Road, and go through the brick columns. Follow the signs to the Visitors' Center and the main parking lot.

This map is more detailed and a little larger, but the bridge is open.
