US 14 joins Illinois Route 43 (IL 43; Waukegan Road) for a short time before turning west onto Dempster Street.

From the south is Northwest Highway coming out of Park Ridge and Chicago; from the north is Rand Road.

Miner Street begins a northwesterly direction into downtown Des Plaines crossing two intersections of US 45 and US 12.

The name Miner Street changes to Northwest Highway after going under a wooden railroad underpass on a large S-curve.

It left Lake Shore Drive for Michigan Avenue and then intersected at Jackson Boulevard (part of US 66 before 1974[6]) where it terminated.
