Route description

First signage on US 14 westbound after its terminus at US 41 in Chicago

U.S. 14 begins in Chicago as Broadway Street on the city's north side. It runs north as Broadway Street and turns northwest onto Ridge Avenue. One half block after crossing Clark Street, U.S. Route 14 turns west onto Peterson Avenue. At Cicero Avenue, Peterson Avenue becomes Caldwell Avenue and travels in a northwest/northern direction entering Niles. U.S. Route 14 joins Illinois Route 43 (Waukegan Road) for a short time before turning west onto Dempster Street. U.S. 14 travels west briefly touching Park Ridge and enters Des Plaines.

Where U.S. Highway 14 crosses Interstate 294 is an unusual intersection where all four street names change. From the south is Northwest Highway coming out of Park Ridge and Chicago; from the north is Rand Road. U.S. Highway 14 continues straight west but no longer as Dempster Street, but now as Miner Street. Miner Street begins a northwesterly direction into downtown Des Plaines crossing two intersections of U.S. Routes 45 and 12. The name Miner Street changes to Northwest Highway after going under a wooden railroad underpass on a large S-curve. U.S. Route 14 continues for most of the rest of its length northwest to Wisconsin designated as Northwest Highway.

Though the name is not used among locals, the entire portion of U.S. 14 in Illinois is given the honorary name Ronald Reagan Highway, which is not to be confused with the Ronald Reagan Memorial Tollway.^[1] U.S. 14 in Illinois is 69.55 miles (111.93 km) in length.^[3]

History

At one point, U.S. Route 14 continued down Foster Avenue to Lake Shore Drive, where it then turned south. It left Lake Shore Drive for Michigan Avenue and intersected U.S. Route 66. It then terminated at what was U.S. Route 20 before it was diverted.
