1948 USGS map showing the Wright-Lockland Highway/Mill Creek Expressway at Shepherd Lane and the former Wright Aeronautical plant, now GE Aircraft Engines. Note that Shepherd/Compton intersects the highway at-grade, so there was probably a traffic light here. North of this intersection, most maps indicate that the highway had 3 lanes in each direction instead of 2. However, there were several at-grade intersections at entrances to the aircraft plant and even a few pedestrian crossings. This divided (but not grade-separated) highway between Shepherd and Glendale-Milford was built around 1941. Note that the west edge of the pavement is dashed to indicate the border of Lincoln Heights. This stretch of highway was upgraded to interstate standards, and the Neuman Way collector/distributor was added at the same time the Lockland Split was constructed in 1964/65.
