Despite these grand visions, in the end the DuPont Highway was constructed in Sussex County as a wide concrete roadway on the proposed right-of-way. The Delaware General Assembly passed the Boulevard Corporation Act of 1911, which authorized the formation of Coleman DuPont Road, Inc., to acquire land and construct a highway the length of the state. Construction of the first section of the highway began near Selbyville on September 18, 1911. By 1912, construction was interrupted by litigation challenging both the constitutionality of the law establishing the road building corporation and the need for DuPont to acquire such a large right-of-way. DuPont offered to make concessions, such as agreeing to pay up to five times the assessed value of a farmer's land five years after the road's completion and reducing the width of the corridor of land to be acquired to . Construction on the highway resumed in 1915 after the litigation had taken its course. The first two sections of the highway, from Selbyville to Georgetown and from Georgetown to the Appenzellar farm south of Milford, were completed on May 24, 1917.
