In 1911, the Coleman DuPont Road, Inc., was established and construction on the highway began. 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 would narrow the proposed right-of-way to in order to compromise with opponents of the highway in addition to offering landowners whose properties were affected by the highway five times the assessed value of the land five years after the highway was completed. The DuPont Highway would end up being built on a alignment with a wide roadway. The length of the DuPont Highway between Selbyville and Wilmington was completed in 1923, with one of the final portions to be completed at the Drawyers Creek north of Odessa. A ceremony marking the completion of the highway was held in Dover on July 2, 1924. The completion of the DuPont Highway improved transportation between northern and southern Delaware and would lead to the expansion of state highways in Delaware.
