the I-55 interchanges between Lemont Road and County Line Road, but not impossible, and taking the north frontage road leads travelers past several sites of historic interest, including Cass Cemetery and the former Martin B. Madden mansion known as Castle Eden (now a Carmelite priory) in Darien as well as the International Harvester experimental fields in Burr Ridge (once known as Harvester, Illinois after the plant located there). Near the Cass Avenue instersection, Route 66 and I-55 pass by the northern edge of the Argonne National Laboratory campus. A mile or so further east near the IL 83 interchange, Dell Rhea's Chicken Basket in Willowbrook is still a popular stop for motorists on the route, although being cut off from the Interstate did cost it a significant amount of business after I-55 was built and during the 1960s through 1980s. At the Indian Head Park interchange with I-294 (Tri-State Tollway), I-55 separates from US 66 to follow a more southerly route as the Stevenson Expressway while Historic US 66 continues eastward on Joliet Road, passing by the historic Lyonsville Congregational Church at Wolf Road and traversing Countryside, Hodgkins and McCook. The original path of Route 66 on Joliet Road intersects the overlapping US 12/US 20/US 45 at LaGrange Road in Countryside before touching the edge of Hodgkins near East Avenue. A brief stretch of Route 66 in McCook between East Avenue and 55th Street west of First Avenue has been permanently damaged by a local quarry and is closed, and Historic US 66 detours onto East Avenue north to 55th Street east before intersecting again with Joliet Road. The detour around the quarry is well marked. In McCook, the route passes by the former Snuffy's 24-Hour Grill, now restored and transformed into the Steak N Egger on Route 66. The route continues northeast on Joliet Road through McCook and Lyons, then jogs north briefly onto Harlem Avenue to Ogden Avenue in Berwyn, where it meets US 34. From Berwyn, Route 66 continues northeast on Ogden Avenue past the Berwyn Route 66 Museum, passing through Cicero before entering Chicago on a diagonal and progressing through the Greater Lawndale area, where it divides North Lawndale from South Lawndale before moving through Douglass Park, the Tri-Taylor Historic District and the Illinois Medical District on the Near West Side. Turning due east from Ogden Avenue once north of the I-290 (Eisenhower Expressway), Route 66
