 In 1983, AASHTO approved for the realignment of US 301 to follow a newly aligned DE 896 east from Mount Pleasant to Boyds Corner, where it would continue north along US 13 to the I-295 / US 40 interchange in Farnhurst; this change was implemented in 1985. The concurrency with DE 71 between the Maryland border and Summit Bridge was removed by 1987. By 1990, US 301 became concurrent with DE 71 again between Middletown and Mount Pleasant. AASHTO approved for US 301 to be realigned to follow DE 896 between Mount Pleasant and US 40 in Glasgow, US 40 between Glasgow and State Road, and US 13 / US 40 between State Road and I-295 in Farnhurst in 1992. However, US 301 is only signed up DE 896 to US 40 in Glasgow. By 1996, US 301 and DE 896 were rerouted to bypass Glasgow to the east, with the former alignment becoming DE 896 Bus. In July 2008, a widening project began on US 301 / DE 299 between United Drive and the east end of the concurrency. This widening to four lanes was completed in November 2010.
