Illinois Route 59 Expansion Project and Open House
The City of Naperville and Illinois Department of Transportation (IDOT) are holding an open house regarding the Route 59 Expansion Project. Attendees will learn about diverging diamond interchanges (DDI), an innovative design which is being considered for the I-88/Route 59 interchange. Compared to the conventional interchange design, the DDI offers many benefits, including fewer conflict points, reduced vehicular delay, and reduced environmental impact. No formal presentations will be given, but representatives from the City of Naperville, IDOT, and Teng and Associates, Inc. will be available to answer questions.
For more information regarding DDI, also referred to as double crossover diamond interchange (DCD), the U.S. Federal Highway Administration just released a tech brief [PDF]. The draft GO TO 2040 regional comprehensive plan endorses the development of innovative designs that reduce delay and improve safety.
This open house will take place Wednesday, July 14, 2010, from 5:00 to 7:oo p.m. at the Naperville Municipal Center, Council Chambers, 400 S. Eagle St., Naperville, IL.
