 On May 19 , 2003 , Governor Ruth Ann Minner cut the ribbon for the final section of the DE 1 toll road between US 13 north of Smyrna and US 13 south of Odessa . This section opened to traffic two days later . As a result , DE 1 was moved off US 13 between Smyrna and Odessa . The total cost to build the toll road was $ 900 million and it was the largest public works project in Delaware history . As part of building DE 1 , DelDOT created new wetlands to replace the ones that were lost in construction of the highway . As a result of the completion of the final section , the northbound exit and southbound entrance with US 13 south of Odessa was removed .
