Illinois Route 54 (IL 54) is a 109.35-mile-long (175.98 km) east–west highway in east-central Illinois. It passes through the cities of Clinton, Gibson City, and Onarga. Its western terminus is at Interstate 55 (I-55) in Springfield. Its eastern terminus is at U.S. Route 45 (US 45) at Onarga, one mile (1.6 km) east of I-57.[1]
IL 54 runs southwest-to-northeast from Springfield. It is now mainly a local road, as I-55 and I-57 have become preferred for long distance travel in the region.
Until 1972, IL 54 was signed as US 54. US 54 now terminates between Pittsfield and Griggsville at mile marker 35 on I-72/US 36. The US 54 alignment between this point and IL 54's current western terminus has since been replaced by the combined I-72/US 36 freeway and I-55. This is a gap of 78 miles (126 km).
