context_page_description: U.S. Route 20 in Indiana is a main east–west highway that is parallel to the Indiana Toll Road. The western terminus of US 20 is at the Illinois state line and the eastern terminus is at the Ohio state line. US 20 through Whiting, East Chicago, and Gary is concurrent with US 12 twice. The route varies between one-way, two-lane, and four-lane streets, in northwestern Indiana. From the east side of Gary to west of South Bend, US 20 is a four-lane undivided highway. The route then heads around the west and south sides of South Bend and Elkhart as a four-lane limited access divided highway. East of State Road 15, US 20 is two-lane rural highway.
  US 20 was part of the Dunes Highway from the Illinois state line to Michigan City, concurrent with US 12. The Dunes Highway started being paved in 1922. The section of the highway that is known as Lincoln Way was part of the 1913 section of the Lincoln Highway. Indiana State Highway Commission, later renamed Indiana Department of Transportation, began signing US 20 in 1926. US 20 went through downtown South Bend and Elkhart before the St. Joseph Valley Parkway was built.
context_section_description: US 20 enters Indiana concurrent with US 12 and US 41, at which point it passes under the Indiana Toll Road.  The road passes by both commercial and industrial areas, between Wolf Lake and Horseshoe Casino.  US 12, US 20, and US 41 are concurrent until US 41 turns south on Calumet Avenue.  US 12 and US 20 head southeast toward East Chicago; in East Chicago, US 12 turns east and US 20 continues south.  US 20 meets State Road 312 (SR 312) and passes under the Indiana Toll Road.  US 20 turns left onto Michigan Street and heads east to Gary passing both industrial and residential areas.  On the way to Gary, US 20 has an interchange with SR 912; at the interchange, the road name changes to 5th Avenue. Just west of Gary, US 12 and US 20 have a concurrency.
  US 12 and US 20 are concurrent through most of Gary.  From Bridge Street to Vermont Street, the eastbound traffic of US 12/US 20 is on 5th Avenue and westbound traffic is on 4th Avenue.  East of downtown Gary, the eastbound and westbound lanes merge to form the Dunes Highway.  Before reaching the neighborhoods of northeastern Gary, the Dunes Highway has an interchange with Interstate 65 (I-65) and I-90/Indiana Toll Road.
  Shortly thereafter, US 12 leaves to the northeast toward Michigan City and US 20 heads east then northeast, forming a major retail corridor through the neighborhoods of Aetna and Miller Beach.  US 20 then meets SR 51 at the state road's northern terminus, near the boundary between Lake Station and Gary.  Just west of Portage, the road passes under I-94.  In Portage, the route has intersections with both SR 249 and SR 149.  The road now enters Burns Harbor and has interchanges with I-94 and SR 49, just south of the Indiana Dunes.  The route heads northeast until Town of Pines, where it intersects with SR 520.  After Pines, the route heads due east to US 421 in Michigan City.
  From US 421, the route heads east and then northeast around Michigan City. On the east side of Michigan City the route has an interchange with both SR 212 and I-94 followed by an intersection with the northern terminus of US 35.  After US 35, the route becomes a four-lane undivided highway until Rolling Prairie, passing SR 39 at Springville.  East of Rolling Prairie the route meets SR 2.  US 20 heads northeast and then east and SR 2 heads due east.  The route passes through Hudson Lake and New Carlisle before South Bend.
