Lancaster County conducted a feasibility study of the U.S. 30 and U.S. 23 corridors in 1985 and concluded that a single project should be evaluated to relieve congestion on both highways. In 1986, PENNDOT initiated a corridor and design location study along with preparation of an EIS for the combined U.S.23/30 project. After a range of preliminary corridor alignments was identified, a preliminary alternatives was conducted and coordination with the public was initiated.

Most of the preliminary corridors were located on new alignment and would have created extensive impacts on agricultural and Plain Sect communities. These alternatives generated unprecedented public controversy (spurred by outside agitators it was later learned). In early 1988, Governor Casey made a public statement that the project would be modified to avoid the impacts on Lancaster County agriculture. As a result, PENNDOT initiated separate studies of the U.S. 23 and U.S. 30 corridors.

In the late 1980’s, a reconstruction of the section of U.S. 30 from the bypass of Lancaster to PA 896 was completed. This reconstruction was initially intended to extend further eastward to Kinzers. But residents of Paradise and Kinzers opposed the project, expressing concerns about residential and business relocations required and noise impacts. Consequently, PENNDOT reduced the scope of that reconstruction.

This study first began in the mid-1990’s. It took up where the 5-lane reconstruction project ended and further extended the project area eastward to Gap.
