A traffic safety analysis by the N.C. Department of Transportation's Safety Planning Group conducted 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 median also acts as an area where drivers can slow and
attempt to regain control of their vehicles and is an important safety feature
of a high-volume or high-speed roadway. 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 design options – referred to as 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.
NCDOT held a drop-in public meeting on Dec. 16, 2021 for updates on N.C. 150 in the Mooresville area.
