I-474's parent Interstate is I-74. As the first digit of the Interstate's number is even, it follows the established convention of providing a loop around a city. I-474 is Template:Convert long. I-474 is the highest numbered route in the state of Illinois.[1] It is also, excluding the proposed I-274 in North Carolina, the only auxiliary route of I-74.
Route description
I-474 is a modern, Interstate-standard four-lane freeway for its entire length. Prior to 2006, through truck traffic on I-74 was instructed to use I-474. This is because prior to its 2004–2007 reconstruction, I-74 was significantly below Interstate standard, having numerous Template:Convert on- and offramps, extremely short merging space for onramps (some less than Template:Convert in length),[2] Template:Cns
The Illinois Route 116 (IL 116) access interchange at Maxwell Road has been indicated as the eastern terminus for the Quincy to Peoria expressway now known as the IL 336 project.[3]
The western terminus of I-474 is at I-74 exit 87A. The eastern terminus of I-474 is at I-74 exit 99. North of the western terminus, the road continues as IL 6 with a new series of exit numbers.
History
I-474 was constructed through the mid-1970s. The now-named Shade–Lohmann Bridge was erected in 1973. During that year, $30.1 million (equivalent to $Template:Formatprice in Template:Inflation/yearTemplate:Inflation/fn) was allocated for acquisition of right-of-way, grading work, and overpass/bridge construction across the whole length of the highway.[4]
