 That will require construction of a Horvati interchange south of the Lučko toll plaza.A total of 361 structures—bridges, viaducts, flyovers, underpasses, passages, wildlife crossings, and tunnels—have been completed on the motorway between Zagreb and Vrgorac, and calculations indicate that 18.6 percent of the route between Zagreb and Split is located on those structures, which is a quite considerable percentage for a motorway of this length.By June 2011, Ravča-Vrgorac section was completed, including 5 viaducts, 4 flyovers and a tunnel.
