NCDOT is using a process called "Design-Build," in which a team of designers and contractors are responsible for a project's design, right-of-way acquisition construction and other aspects. The method reduces overall construction time, helps NCDOT avoid cost inflation, allows the contractor to make innovations that save taxpayers money, lessens the environmental impact of the project and alleviates any driving delays for motorists.
The Design-Build process for the Business 40 improvements project has two phases.
Phase I involves improvement to Peters Creek Parkway and other area roadways to manage traffic during Phase II of the project. Work includes:
- Widening Martin Luther King Jr. Boulevard between Marchall and Trade streets
- Improving the intersection at Peters Creek Parkway and Academy Street
- Replacing and widening the Peters Creek Parkway bridge over Business 40
- Widening and enhancing the ramps at the Peters Creek Parkway interchange
- Widening Peters Creek Parkway from the interchange to First Street
- Building temporary improvements at various intersections to better handle detoured traffic
- Conducting limited work on Business 40 to prepare for its closures
Phase II, which will involve closing I-40 for no more than two years, will begin in late 2018 or early 2019 after Phase 1 is complete. Work involves removing and repaving the interstate and replacing 10 bridges.
