(September 12, 2007) - Meridian Systems, a provider of enterprise project management software for optimizing capital projects, programs and facilities, today announced that Constructech magazine honored the Illinois Tollway at the 2007 Vision Awards on August 23 at the annual Constructech Technology Day event.

The Illinois Tollway has been honored for its use of Proliance® On Demand software to manage their Congestion-Relief Program (CRP)-Open Roads for a Faster Future-which is a multi-billion dollar capital program designed to rebuild and reduce congestion on the nearly 50-year-old Illinois Tollway System. The program rebuilds/restores nearly all of the 274-mile system, widens/adds lanes to many miles of existing roads, converts 20 mainline toll plazas to Open Road Tolling, and extends the North-South Tollway (I-355) south from I-55 to I-80 in Will County, one of the fastest growing areas in the State of Illinois.

The Illinois Tollway selected Proliance software because of its unique ability to manage complete capital project lifecycles in one enterprise solution. More information about the CRP and the Illinois Tollway is available at the Illinois Tollway's Web site at www.illinoistollway.com.

"We congratulate the Illinois Tollway, as well as HNTB and KFA, for this honorable recognition," said Sue Watkins, Director of Marketing at Meridian Systems. "We are pleased that Proliance can help capital project owners, like the Illinois Tollway, implement an ILM (Infrastructure Lifecycle Management) solution that can improve business practices and gain efficiencies in managing the plan, build, and operate process."

More than 750 Tollway project management personnel utilize Proliance software in Meridian's On Demand hosted environment, which provides several key benefits including: real-time Project Management with Ball-in-Court responsibility; critical path reporting; faster application deployment; lower initial investment; and application scalability as business demands increase.
