For funding purposes, the proposed work to convert Capital Boulevard (U.S. 1) – between I-540 in Raleigh and Purnell/Harris roads in Wake Forest – to a controlled-access highway would be divided into four segments.
|Segment A||I-540 to north of Durant Road/Perry Creek Road |
|Segment B||North of Durant Road/Perry Creek Road to north of Burlington Mills Road|
|Segment C||North of Burlington Mills Road to south of N.C. 98 Business (Durham Road)|
|Segment D||South of N.C. 98 Business (Durham Road) to Purnell Road/Harris Road|
Converting the roadway to a controlled-access highway would limit entry onto the roadway via ramps at interchanges.
Traffic signals on Capital Boulevard within the study area are proposed to be removed and replaced with interchanges at:
Other proposed work would include:
Existing interchanges improvements at I-540, N.C. 98 Bypass (Dr. Calvin Jones Highway) and N.C. 98 Business (Durham Road)
A bridge at Jenkins Road/Stadium Drive
A third lane on I-540 westbound at the Capital Boulevard interchange
The N.C. Department of Transportation will also study service roads and local connections to maintain access to properties along the corridor.
The Capital Boulevard upgrade would be a design-build project. The design-build process allows NCDOT to hire a team of designers and contractors who are responsible for the design, right of way acquisition and project construction. The team might begin construction on one portion of the project while it finishes the design and right of way acquisition for others. This usually results in faster completion of a project.
Other benefits to a design-build project might be innovative solutions that save time or money or reduce impacts and quicker resolution to problems that might arise during design and construction. The process might provide additional alternatives or modifications to the existing alternatives, which might reduce costs or impacts.
