 Traffic congestion at the cloverleaf interchange with I @-@ 95 in Christiana led to DelDOT to improve the interchange . The project included adding flyover connecting ramps from northbound DE 1 to northbound I @-@ 95 and from southbound I @-@ 95 to southbound DE 1 which allowed for easier merging patterns and the elimination of lengthy backups on the former ramp design . Construction of a new " ring access road " around Christiana Mall began in February 2011 and was completed in March 2012 , with a newly built bridge over DE 1 , just south of the I @-@ 95 interchange . The ramp from southbound I @-@ 95 to southbound DE 1 / DE 7 opened on August 27 , 2013 and the ramp from northbound DE 1 / DE 7 to northbound I @-@ 95 opened on October 17 , 2013 , with a ribbon cutting ceremony attended by Governor Markell and DelDOT secretary Bhatt .
