 Further construction of motorways from Zagreb to Rijeka and Split was suspended for the next 28 years following a political decision of the Croatian leadership, newly installed during Yugoslav suppression of the Croatian Spring, to "stop megalomaniac projects".It is considered that the true reason for the cancellation of the works was that the motorway was considered to be a "nationalist" project.The conclusion is supported by the fact the road was spontaneously nicknamed "King Tomislav Motorway" () by citizens investing their money through the public loan after the first king of medieval Croatia, who united Croatia as a single kingdom in 925.
