    Intersection, interchange spacing guidelines

    I'm looking over our MPO's TIP project sheet and see an a proposed interchange project that, on the face of it, looks like it might violate Interstate interchange spacing standards. Can anyone refer me to definitive source on interchange spacing standards?

    I would contact the FHWA (USDOT - Federal Highway Administration) or, since you say that you are in the Nashville, TN area, TnDOT. Both will have the official design standards book for interstates.
