 Between 1958 and 1971 , studies were conducted for a bypass of the segment of US 13 through Dover along with a connector between Dover and Frederica . The proposed routing began at US 113 and DE 12 north of Frederica and continued northwest to Woodside , where it was planned to cross US 13 . From here , the bypass was to run to the west of Dover and head north to its terminus at US 13 north of Cheswold . As part of planning of the Dover Bypass , an archaeological survey had to be conducted along part of the proposed route between 1972 and 1975 . By 1976 , construction of the Dover Bypass was postponed indefinitely . From 1971 to 1978 , a north @-@ south extension of the Delaware Turnpike between Wilmington and Dover was studied . This extension was proposed to run from north of I @-@ 95 in Ogletown south to US 13 near Camden . The toll road would head south from Ogletown and cross the Chesapeake and Delaware Canal on the Summit Bridge to reach a connector to US 301 near the Maryland border . From here , the turnpike would bypass Middletown , Clayton , Smyrna , and Dover to the west before coming to US 13 . Intermediate interchanges were to be located west of Dover , at DE 6 west of Smyrna , west of Middletown , at DE 896 south of the Summit Bridge , DE 71 north of the Summit Bridge , US 40 , and I @-@ 95 . The north @-@ south extension of the Delaware Turnpike was to have a combination of ramp tolls and mainline toll barriers . Three mainline toll barriers were to be located between I @-@ 95 and US 40 , between Middletown and Smyrna , and north of Camden . The projected cost of the project in 1972 was $ 107 million .
