A traffic barrier, comprising: a body, the body comprising: a skirt section, extending upwards and having a positive slope; an intermediate section comprising a lower portion that extends upwards from the skirt section, a central portion that extends upwards from the lower portion, and an upper portion that extends upwards from the central portion; the lower portion having a positive slope having an angle greater than the slope of the skirt; the upper portion having a negative slope; a head section above the upper portion; the head section having a negative slope having an angle less than the slope of the upper portion; a first end, and an opposite second end; and a vertical end channel formed on each of the first and second ends (50, 52); a lower tension bar located within the skirt section, having a lower first tab extending through the channel of the first end and having a lower second tab extending through the channel of the second end; an upper tension bar located within the head section, having an upper first tab extending through the channel of the first end and having an upper second tab extending through the channel of the second end; and, the upper first tab and lower first tab of a first traffic barrier being pivotally connectable to the upper second tab and lower second tab of an adjacent second traffic barrier; wherein each slope has a direction running from its lowest vertical point to its highest vertical point, each positive slope is defined as a slope having a direction that runs inwards towards a vertical centerline, and each negative slope is defined as a slope having a direction that runs outwards away from the vertical centerline. a body, the body comprising: a skirt section, extending upwards and having a positive slope; an intermediate section comprising a lower portion that extends upwards from the skirt section, a central portion that extends upwards from the lower portion, and an upper portion that extends upwards from the central portion; the lower portion having a positive slope having an angle greater than the slope of the skirt; the upper portion having a negative slope; a head section above the upper portion; the head section having a negative slope having an angle less than the slope of the upper portion; a first end, and an opposite second end; and a skirt section, extending upwards and having a positive slope; an intermediate section comprising a lower portion that extends upwards from the skirt section, a central portion that extends upwards from the lower portion, and an upper portion that extends upwards from the central portion; the lower portion having a positive slope having an angle greater than the slope of the skirt; the upper portion having a negative slope; a head section above the upper portion; the head section having a negative slope having an angle less than the slope of the upper portion; a first end, and an opposite second end; and a vertical end channel formed on each of the first and second ends (50, 52); a lower tension bar located within the skirt section, having a lower first tab extending through the channel of the first end and having a lower second tab extending through the channel of the second end; an upper tension bar located within the head section, having an upper first tab extending through the channel of the first end and having an upper second tab extending through the channel of the second end; and, the upper first tab and lower first tab of a first traffic barrier being pivotally connectable to the upper second tab and lower second tab of an adjacent second traffic barrier; wherein each slope has a direction running from its lowest vertical point to its highest vertical point, each positive slope is defined as a slope having a direction that runs inwards towards a vertical centerline, and each negative slope is defined as a slope having a direction that runs outwards away from the vertical centerline.
