The project began August 25, 2003. Six alternatives were developed and presented to the public at a workshop on July 20, 2004. Based on input from the public, natural and cultural resources agencies, and emergency response units, a preferred alternative was selected and presented to the public at a workshop on October 26, 2004. The environmental documentation and approval process was completed in June 2010. The final design phase began in 2006 and is complete. Right-of-way acquisition began in 2010 and is also completed.
Program addresses a 31-mile section of this highway between Nassau in Sussex County and the Dover Air Force Base (DAFB) in Kent County, south of Dover. SR 1 serves as the main north-south highway to access the Delaware Beach resort areas. In addition to the resort traffic, eastern Sussex County has been experiencing a high rate of growth in year-round residential traffic and supporting commercial development. This has led to increased congestion and safety issues due to increased travel demand and the mixing of local and through traffic.
The need for corridor capacity preservation on this section of SR 1 is clearly demonstrated in the high volumes of existing and future projected traffic, along with following the guidelines as set forth in the Strategies for State Policies and Spending. The program supports not only the State Investment Strategies, but also Livable Delaware , because it encourages and facilitates growth within the designated areas while discouraging growth outside of those non-designated growth areas.
