 In March 2000 , groundbreaking took place for the final segment of the DE 1 freeway between Smyrna and Odessa . The interchange at the Dover Air Force Base main gate was completed in July of that year . The construction of the final segment resulted in a portion of US 13 south of Odessa being shifted further east as DE 1 would be built on top of the road . A service road would serve properties on the southbound side of US 13 . In October 2001 , northbound US 13 was realigned to the new alignment south of Odessa in order to build DE 1 in that area . In May 2002 , US 13 was shifted to a new southbound alignment south of Odessa , with the former portion of the route in that area becoming a service road known as Harris Road . On September 5 , 2002 , a partial interchange opened at DE 8 in Dover , utilizing existing emergency vehicle ramps . This interchange was included in the initial plans for the highway but was dropped due to low traffic volumes . As part of building the interchange , DelDOT purchased development rights to adjacent land parcels in order to prevent additional development in the area of the interchange .
