on the Illinois and Michigan Canal. The Chicago & Rock Island Railroad and Michigan Central came through in the 1850s, and the Atchison, Topeka and Santa Fe Railway and Chicago & Alton Railroad soon followed, with the Elgin, Joliet and Eastern Railway and Milwaukee Road lines built around the turn of the century. U.S. Highways 6 (the Grand Army of the Republic Highway), 30 (the Lincoln Highway), 45, 52, and 66 (Route 66) all ran through the city. In the 1960s, Interstate 55 and Interstate 80 made their way through Joliet, linking up near Channahon just west of the city limits. The phrase "Crossroads of Mid-America", found on the Joliet seal, is an allusion to the intersection of I-80 and I-55. Joliet Transportation Center is the final stop on the Metra rail lines from Chicago for the Heritage Corridor route from Chicago Union Station and the Rock Island District route from LaSalle Street Station. A third line, the STAR Line, would have also terminated at the station, but the project was shelved as of 2012. PACE provides local bus service six days a week (no service on Sundays) with buses leaving from a terminal in downtown Joliet once an hour. Amtrak serves Joliet Union Station daily via its Lincoln Service and Texas Eagle routes. Service consists of four Lincoln Service round-trips between Chicago and St. Louis, and one Texas Eagle round-trip between San Antonio and Chicago. Three days a week, the Eagle continues on to Los Angeles. Airports The Joliet Regional Airport is located off Jefferson Street near Interstate 55. Lewis University Airport is located to the north in the nearby village of Romeoville and is owned by the Joliet Regional Port District.
