Project Overview and Purpose
Planning is underway on a proposed project to improve traffic capacity and reduce congestion on a 15-mile stretch of N.C. 150 – from N.C. 16 Bypass in Catawba County to just west of the U.S. 21/N.C. 150 interchange in Mooresville in Iredell County.
The N.C. Department of Transportation is also studying improvements to the I-77/N.C. 150 interchange (STIP I-5717).
The Federal Highway Administration on March 8, 2016, approved and finalized the Environmental Assessment – a federally required document that details NCDOT's findings on how the proposed project would affect the environment. The approval made way for NCDOT to study and seek public input on two options to widen N.C. 150 – referred to as build alternatives – in the project area:
- Alternative 1, which widens N.C. 150 on the existing roadway
- Alternative 2, which widens N.C. 150 on the existing roadway but also incorporates a bypass around the Terrell Historic District, thereby avoiding impacts to the district (this option is being studied in pursuant to Federal Highway Administration requirements)
As required by the National Environmental Policy Act, also under review is the No-Build Alternative, in which N.C. 150 in the project area would not be widened.
A "continuous flow intersection" is proposed for construction in Mooresville at the intersection of Williamson and Bluefield roads. In a continuous flow intersection, vehicles turning left cross opposing lanes of traffic at a signal-controlled crossover, before reaching the intersection.
A traffic safety analysis by NCDOT's Safety Planning Group in June 2011 found that crash rates on the 15-mile stretch of N.C. 150 exceed the statewide crash rates in the total non-fatal injury and wet-condition categories and exceed critical crash rates in the total and non-fatal injury categories.
A report on the traffic safety analysis concluded that a divided roadway with a raised median "should potentially reduce frontal impact crashes along the corridor." The report also recommended that a driveway access review be conducted to determine if driveways can be closed or combined to reduce conflict points.
A traffic forecast completed in September 2013 found that:
- N.C. 150 traffic volumes exceeded two-lane capacity between Sherrill's Ford Road and the I-77 Interchange commercial district
- N.C. 150 traffic volumes west of Sherrill's Ford Road are projected to exceed capacity between 2015 and 2020
- The projected length of N.C. 150 will exceed two-lane capacity by 2035
NCDOT collected public feedback on the proposed project's Environmental Assessment and build alternatives during a public comment period that ended Sept. 23, 2016. In addition, there were two public meetings – one in Maiden on Aug. 22, 2016, and another in Mooresville on Aug. 23, 2016.
All comments – regardless of how they are submitted – carry equal weight and will be taken into consideration as part of the project development process.
The maps and materials available at the meeting are available on this page under Project Documents.

Resources for Local Property Owners
In many cases, it is inevitable that a certain amount of private property must be acquired. The displacement of homes and businesses is minimized to the extent practicable. The following brochures will answer questions about this process.
