its route for the Avenue of the Saints: The Expressway would follow Interstate 35 from St. Paul to a point south of Clear Lake, Iowa; U.S. Route 18 to Charles City, Iowa; U.S. Route 218 to Cedar Falls, Iowa; Iowa Highway 58 and U.S. Route 20 around Cedar Falls and Waterloo, Iowa; Interstate 380 from Waterloo through Cedar Rapids to Interstate 80 near Coralville, Iowa and Iowa City, Iowa; U.S. 218 to Donnellson, Iowa; Iowa Highway 394 and Route B to Wayland, Missouri; and following U.S. 61 and Interstate 64 from Wayland through Missouri, west of the Mississippi River, to St. Louis. The route exclusively serves Iowa and Missouri, using existing interstates in Minnesota and St. Louis area for routing to terminus "Saint" cities. This routing provides Quincy, IL with access to the Avenue of the Saints via a 10-mile segment of U.S. Route 24 from Taylor, Missouri. Amtrak service and expansion (1971−present) Denied access to the US Interstate highway network, the "Illinois Service" initiative for Amtrak rail service was approved in 1971. It is partially funded by the Illinois Department of Transportation. The Illinois Zephyr began daily round-trip service from Chicago to Quincy in 1971, through the heart of the region. Amtrak's Southwest Chief and California Zephyr share trackage with the Illinois Zephyr as far as Galesburg. The state of Missouri's "Missouri Service" only funded the extension of the Ann Rutledge to provide daily service between Kansas City and St. Louis with continuing services to Chicago via Springfield. The Illinois Zephyr has become one of Amtrak's most successful routes, and is the longest continuously-operated state-supported route in the Amtrak network. As part of the Midwest Regional Rail Initiative and Illinois's partnership with Amtrak an additional daily train service on this Chicago-Quincy line was added on October 30, 2006. This service expansion is part of the state sponsorship for increasing round-trip train service between Chicago and downstate cities from three daily to seven daily schedules. The new Carl Sandburg train joined the existing Illinois Zephyr to provide both a morning and evening train in each direction. Proposals have been considered to extend the two routes across the Mississippi River to Hannibal and/or St. Louis. In February 2009, Thomas C. Carper, mayor of Macomb from 1991 to 2003, was elected as Chairman of Amtrak's Board of Directors for a 4-year term, until February 2013. Mr. Carper rejoined the Amtrak Board of
