to Nassau to prevent excessive development along the corridor so it can gradually be transformed into a freeway. Dover freeway upgrade and truncation The southernmost part of the Korean War Veterans Memorial Highway, from south of DE 10 to north of Bay Road, was placed under construction in 1990 and opened along with the Dover–Smyrna portion of DE 1 in 1993. US 113 traffic needed to use a temporary tie-in during construction, and after the new freeway opened, traffic on the U.S. Highway needed to use Exit 95 to transfer between the new freeway and Bay Road. The extension of the DE 1 freeway south through Dover Air Force Base was constructed later due to the need to coordinate negotiations with the military installation and to allow the base to remediate hazardous material sites, maintain security and access restrictions with construction of a new Main Gate, and reconstruct base housing on the west side of the highway. The Main Gate to Dover Air Force base was moved further east, and a diamond interchange was built between the Main Gate and the base housing area. The upgrade of US 113 and DE 1 through the military base was built in two phases, the first from 1996 to 1998 and the second in 1999 and 2000. The final piece of the Relief Route associated with US 113 was the Puncheon Run Connector, which would provide a direct connection between US 13 and DE 1 and US 113. The connector and its partial interchange with US 113 were built between 1998 and 2000. In 2003, the same year the last portion of the Relief Route was completed, DelDOT requested US 113 be eliminated from Milford to Dover in favor of the sole designation of DE 1 from Milford to Dover. AASHTO denied DelDOT's application at their spring 2003 meeting because the state did not address the status of US 113 Alternate. The organization approved DelDOT's application to also eliminate US 113 Alternate in addition to the Milford–Dover portion of US 113 at their annual meeting later in 2003. Bay Road became an unnumbered highway between Exit 95 at Dover Air Force Base and the old northern terminus of US 113 at US 13 in Dover. Snow Hill to Berlin expansion Following the expansion of US 113 from Berlin to the Delaware state line, MDSHA turned its attention toward the remaining of two-lane highway
