It is an honor to serve as your Lake County Board Chairman.  We are working hard to ensure Lake County continues to be a great place to live, work and do business by investing in roads and infrastructure, preserving open space, and promoting economic development.  Our efforts to expand, improve and maintain our transportation network are critical to maintaining a high quality of life for Lake County families and workers.  To accomplish this, we are investing a half billion dollars over the next six years to improve our regional transportation system, and working hard to advance the IL Route 53/120 extension project.
