Varaždin bypass

North-eastern subsection, carried out of the Podravska intersection to the south direction, was officially opened for traffic in November 1985 – its 1.9 km (1.2 mi) long route required the construction of two overpasses (across R201 and R202 railroads) at the southern-most part of the subsection. The overpass above R201 railway (called „Gospodarska overpass“ ; Croatian: Nadvožnjak Gospodarska, during the time of Yugoslavia: „Overpass of November 29“ ; Croatian: Nadvožnjak 29.11.) physically separates from the circular route of the bypass, being built at almost right angles to the west just south of the overpass over R202 railway (called „Vilko Novak overpass“ ; Croatian: Nadvožnjak Vilka Novaka), at this point connecting the motorway with the city area (more precisely with the present-day Zagrebačka Ulica street). These two overpasses are connected with Gospodarska intersection (named after „Gospodarska Street“ ; Croatian: Gospodarska Ulica). North-eastern part of the bypass was intended to divert entire international and local traffic which flowed through the city center from direction of Hungary and Međimurje County, but also from Slovenia and Austria. This portion connected the traffic routes between Koprivnica and Zagreb, and with the connection to the previously constructed northern bypass, it enabled diversion of all traffic from Čakovec and Maribor to Zagreb. On this way, extremely difficult traffic situation in Varaždin became easier as the large international traffic (especially heavy trucks) from Austria to Zagreb and other cities in the region started to avoid the roads inside the city.[4]

Completion of the north-eastern part of the bypass, however, did not entirely resolve all traffic problems, because the part between Varaždin and the village of Turčin (5 km / 3.1 mi south) wasn't yet created. Eventually, 3.1 km (1.9 mi) long south-eastern subsection between Gospodarska intersection and Turčin was opened in 1990 as a two-lane motorway. In July 1998, upon completion of the A4 section between Čakovec and Varaždin, Kneginec intersection was created, as the state road 528 (which offers Varaždin freeway connection) was carried out of the bypass. Before the south-eastern subsection came into existence, the main way to travel from Varaždin towards south and vice versa was through Zagrebačka Ulica street (during the time of Yugoslavia: „Marshal Tito's Street“ ; Croatian: Ulica Maršala Tita), with the route located between the city area and Turčin that stretches on the west side from the present-day bypass). As the subsection of the bypass included building of the 1.3 km (0.8 mi) long portion of the road south from present-day Kneginec intersection (today part of the state road D3), northern part of Zagrebačka Ulica became physically interrupted in Turčin, though a connection to the newly built portion is arranged in a way of turning it into a major corridor some 1 km (0.6 mi) before its dead end. State road D3 nowadays covers the original corridor of Zagrebačka Ulica between the point of its northern part termination and the village of Presečno, bearing the same street name. South-eastern subsection was upgraded to four-lane highway between 2012 and 2014.[5]
