context_page_description: U.S. Route 41, also U.S. Highway 41, is a major north–south United States Numbered Highway that runs from Miami, Florida, to the Upper Peninsula of Michigan. Until 1949, the part in southern Florida, from Naples to Miami, was US 94. The highway's southern terminus is in the Brickell neighborhood of Downtown Miami at an intersection with Brickell Avenue, and its northern terminus is east of Copper Harbor, Michigan, at a modest cul-de-sac near Fort Wilkins Historic State Park at the tip of the Keweenaw Peninsula. US 41 closely parallels Interstate 75 from Naples, Florida, all the way through Georgia to Chattanooga, Tennessee.
context_section_description: US 41 enters Illinois cosigned with US 12 and US 20 on Indianapolis Boulevard beneath the Chicago Skyway. At the Illinois–Indiana state line, US 41 enters the Chicago city limits. The three US routes run together northwest along Indianapolis Boulevard then cut north on Ewing Avenue on the south side. At 95th Street, US 12 and 20 head west.  US 41 then runs along the lake amongst the newly developed extension of Lake Shore Drive, which extends from the intersection of Ewing Avenue and Harbor Drive and continues  northwest until it reaches 79th St and South Shore Dr. US 41 then continues down South Shore Drive through the South Shore neighborhood and then turns and moves in a northerly direction at the intersection of South Shore Drive and Marquette Drive (Lake Shore Drive continues north while Marquette continues south and eventually becomes Jeffery Blvd.)
  US 41, as Lake Shore Drive, passes by the Museum of Science and Industry (at 57th Street) in the Hyde Park area. From here north, US 41 is a quasi-expressway with bridges too low to admit trucks, and a 45 mph (72 km/h) speed zone, and exits at 53rd Street/Hyde Park Boulevard, 50th Street, 47th Street, Oakwood Boulevard, 31st Street, Interstate 55, and 18th Street. After the I-55 bridges, US 41 passes McCormick Place, which is the largest convention center in North America. At this point, the roadway becomes a boulevard passing the Museum Campus (Field Museum, Shedd Aquarium, and Adler Planetarium) and Soldier Field, home of the Chicago Bears; access to these attractions is provided at 18th Street.
  The roadway continues north with a couple of signals as it passes through Grant Park and by Buckingham Fountain. After the signal at Monroe Street, the roadway becomes a quasi-expressway again with exits at Randolph Street/Wacker Drive, Illinois Street/Grand Avenue (Navy Pier exit), and a signal at Chicago Avenue. The roadway then has a sharp S-curve called the Oak Street Curve where the suggested speed limit is 25 mph (40 km/h). After the curve, US 41 is a full expressway. US 41 exits at Foster Avenue but Lake Shore Drive continues north to Bryn Mawr Avenue and Hollywood Avenue before ending.
  At Broadway, US 41 intersects the eastern terminus of US 14. US 41 continues along Lincoln Avenue in the north side of the city, eventually meeting Skokie Boulevard/Cicero Avenue, where US 41 turns north and parallels Interstate 94. In the northern suburbs of Chicago, US 41 joins I-94 (Edens Expressway) just north of Lake Avenue for a short distance before splitting from the freeway just south of Lake–Cook Road and continuing north as the Skokie Highway for roughly 25 miles (40 km) to a point near the Wisconsin border. Just south of the border, US 41 rejoins I-94. The two co-signed routes continue northward into Wisconsin.
