The Elgin Bypass or Dr. Martin Luther King Jr. Memorial Highway is the common name for a four-lane freeway that carries U.S. Route 20 (US 20) around the city of Elgin in the northeastern part of the U.S. state of Illinois. The highway forms a southern border to the Elgin street grid. The state-ownership of the land on the southern edge of the city for hospital and highway maintenance purposes eased the right-of-way acquisition. The highway is approximately 5 miles (8.0 km) long.
Construction of the Golf Road (Illinois Route 58) extension to Summit Street in Elgin was completed in 1932. In 1958, Interstate 90 (I-90) was built through the north side of Elgin extending east to Devon Avenue, and on to Chicago by 1960. In 1935, concerned about increasing numbers of traffic, residents of Elgin laid plans to build a bypass. US 20 had been routed down Villa Street, Highland Avenue, and Larkin Avenue through downtown Elgin. 27 years later, a section of freeway opened south of Elgin as the Elgin Bypass.
The segment of the Elgin Bypass between McLean Boulevard and Grace Street (Illinois Route 25), including the Fox River bridge, was opened first. Later, the outer segments of the bypass – to Randall Road on the west, and Bluff City Boulevard on the east – were opened. On November 30, 1962, Governor Otto Kerner Jr. dedicated the Elgin Bypass.
In 2012-2016, the interchange between the Elgin Bypass and McLean Blvd was upgraded to a SPUI, the bridge was widened and replaced and portions of the Bypass were repaved at a cost of $44.4 million.
In 2019, the interchange between the Elgin Bypass and Randall Road is receiving a $9 million upgrade so that northbound Randall Road traffic can enter the eastbound Elgin Bypass without making a left turn at a traffic light.
Starting in 2014, a comprehensive study of the Elgin Bypass corridor resulted in a number of recommendations including a wider bridge across the Fox River, a replacement bridge for IL-31 crossing the bypass and replacement of other bridges. The 2019 estimates of the recommended improvements total $84 million, with $10.6 million designated for the IL-31 bridge.
The entire route is in Elgin. All exits are unnumbered.
