Interpolate along route

I have point data along lines that represents certain values at those locations on a pipeline.  The points are not currently snapped to the lines but are adjacent to the lines.  I would like to interpolate between the points along the line, assuming a linear relationship between distance and value.  The goal is to represent the interpolated values between the known points, which may be 1000 feet apart.  Is there a tool that will do this?  I have looked through all the interpolation tools in spatial analyst but all of the tools return a surface, whereas I want a line with values along it.
