 A new bridge carrying southbound SR 37 over I-81 was built, but otherwise the diamond interchange was not modified.The only change to the major bypass since it was constructed has been a new trumpet interchange serving the Winchester Medical Center; construction began in September 2000 and was completed in November 2001.A single ramp from SR 37 north to Cives Lane, allowing traffic at the north end of the bypass to access US 11 south, was built in about 2000.
