Highway system

In the U.S. state of Illinois, U.S. Route 36 is an east–west highway that runs across the central portion of the state. It runs east from Missouri over the Mark Twain Memorial Bridge over the Mississippi River with Interstate 72. The eastern terminus of U.S. 36 in Illinois is located near the unincorporated area of Raven near the Illinois-Indiana state line. This is a distance of 216.47 miles (348.37 km).[1]

Route description

U.S. 36 parallels the old Wabash Railroad from the Mississippi River at Hannibal, MO east to Decatur, IL. Norfolk Southern Railway operates on this route today.

U.S. 36 is overlapped with Interstate 72 for more than half its routing in Illinois, 133 miles (214 km). At Decatur, I-72 separates from it and travels around the city to the north, while US 36 enters the city passes through downtown on the four-lane Eldorado Street. Just beyond 19th Street, US 36 turns to the southeast on a four-lane divided alignment paralleling a railroad, exiting Decatur on the southeast side. The road crosses Lake Decatur and narrows to two lanes before turning due east. After turning east, U.S. 36 runs largely in a straight line, mostly through open country, until it exits the state.

gollark: Maybe a similar thing to LTSes, where you need to scan through it to find the point where some constraints are satisfied, but checking that requires solving linear equations or something.

gollark: Hmm, I wonder if I can make something with O(n²) string length.

gollark: Length terminated strings of course lack this issue.

gollark: I read that it does !!STRLEN!! somewhere.

gollark: Isn't sscanf kind of O(n²)-y?
