History
Until 2002, Interstate 210 connected with the Kellogg Interchange; that section of the 210 north of the interchange no longer exists as it has been resigned as State Route 57. Generally, transitioning from one freeway to another is efficient and safe because at the time of the interchange's construction, it was not encumbered by existing, surrounding development in the immediate vicinity. Therefore, freeway alignments are straight and the transition roads that connect them have predictable, constant radii.See also
