Interstate 290 (I-290) is an auxiliary Interstate Highway that runs westward from the Chicago Loop. The portion of I-290 from I-294 to its east end is officially called the Dwight D. Eisenhower Expressway. In short form, it is known as "the Ike" or the Eisenhower. Before being designated the Eisenhower Expressway, the highway was called the Congress Expressway because of the surface street that was located approximately in its path and onto which I-290 runs at its eastern terminus in the Loop. I-290 connects I-90 (Jane Addams Memorial Tollway) in Rolling Meadows with I-90/I-94 (John F. Kennedy Expressway/Dan Ryan Expressway) near the Loop. North of I-355, the freeway is sometimes known locally as Illinois Route 53 (IL 53), or simply Route 53, since IL 53 existed before I-290. However, it now merges with I-290 at Biesterfield Road. In total, I-290 is long. Route description Jane Addams Memorial Tollway to Veterans Memorial Tollway This section is long and runs from Rolling Meadows to Addison. It is the portion of I-290 more locally known as "Route 53". Here, I-290 runs largely above-grade through Schaumburg and Elk Grove Village and at- or below-grade through Itasca and Addison. The northern of this highway were reconstructed in 2003–2004. A left shoulder and an auxiliary lane between ramps were added, as well as improved lighting. The highway is four lanes wide (not counting the auxiliary lane) north of IL 390 (milemarker 5) and five lanes wide with a wide left shoulder south to the exit to I-355. Between milemarkers 0 and 4, IL 53 overlaps this section of the Eisenhower Expressway. Eisenhower Extension This section is long and runs from Addison to Hillside. It took its name when the Eisenhower was extended northwest from Hillside. The highway runs largely at-grade or above-grade for this length. US Route 20 (US 20) overlaps I-290 around Elmhurst from milemarkers 12 to 13 and runs parallel to the rest of this section between milemarkers 7 and 18. This section of I-290 varies in width from two lanes at the ramp east from the I-290/I-355 split to three lanes between I-355 and US 20, to three lanes plus two exit lanes at US 20/IL 64 (Lake Street/North Avenue; exit 13B). After exit 13B, the highway reverts to three through traffic lanes. Exit 15 to southbound I-294 is a frequent point of congestion due to ramp traffic backing up onto the mainline
