 There are plans to replace two more at @-@ grade intersections along the route with grade separated interchanges . The two intersections to be upgraded to interchanges are DE 14 in Milford and DE 16 east of Milton . Construction on the interchange at DE 14 in Milford is expected to begin in fall 2017 and be completed in 2019 . The proposed interchange at DE 16 is in the early design stage with construction not projected to begin until 2020 .
