Directors on August 15, 2013 for a five-year term. During fiscal year 2011, both the Illinois Zephyr and Carl Sandburg carried a combined 225,000 passengers, a 6.9% increase over FY2010. The two trains had a total revenue of $5,580,227 in FY2011, a 10.6% increase over FY2010. Central Illinois Expressway / Interstate 72 (1978−2010) The Central Illinois Expressway, the Interstate 72 (I-72) Purple Heart Memorial Highway began in the late 1970s and was completed in 1991. The Interstate 172 spur for Quincy access to the Expressway was completed in 1995. This provided some relief for the southern counties and enabled Interstate access to the cities of Quincy, Pittsfield and Jacksonville from Springfield, Central Illinois and Indiana. Two decades later, the Missouri Department of Transportation, as part of NAFTA High Priority Corridor 61 - Missouri corridors, completed their Interstate 72 and U.S. Route 36 Northern Missouri segment from Hannibal, MO through Cameron to St. Joseph, MO in August 2010. In coordination with Illinois DOT, the route from Cameron, MO to Hannibal, MO is marked as Chicago-Kansas City - Missouri Route 110. Chicago-Kansas City Tollway (1989 studies) In 1989, the idea of a Chicago to Kansas City expressway was revisited. A tri-state economic and highway study was performed and found that a full, limited-access tollway running from the Kansas Turnpike at Kansas City to the Indiana Toll Road at Gary or Tri-State Tollway near the Joliet area would cost $2 to $2.5 billion, if funded entirely by private investors. The study was useful in providing an expenditure number (1989 dollars) to Illinois and Missouri legislatures and public officials for building the highway. Missouri DOT's higher priority from 1989 to 2000 was completing their section of the Avenue of the Saints and 2000 to 2010 for completing the Missouri portion of Interstate 72. Illinois DOT was struggling in 1990s with funding to finish existing highway upgrade projects (Interstate 39, Interstate 172) from the 1980s. Illinois Route 336 (2001−present) In 2009, the construction of Illinois Route 336 from Quincy was extended from Carthage to Macomb partially built along with former U. S. Route 136 alignment, on which it runs concurrently, and a new alignment bypassing Tennessee and Colchester to end temporarily west of Macomb. This provides these communities (Quincy, Carthage, Macomb) with a southwestern connection (Kansas City and St. Joseph, MO) to Interstate 72. A bypass around Macomb was under construction, with funding secured in
