Before the shopping industry, Jankomir was best known for the
Jankomir Bridge, a two-lane
beam bridge used for car traffic going towards the
A3 highway to
Samobor or
Slovenia. The bridge was built in 1958, project having been made by
Krunoslav Tonković. Being 330 meters long, it crosses the
Sava River. The bridge was used as a part of the
Highway "Brotherhood and Unity" (until the
Zagreb bypass was constructed) and later Ljubljanska Avenue. As the Zagreb grew, the bridge's main use shifted from serving transit traffic with touristic and intercity travel purpose, to being used mostly by commuters from outer suburbs. The traffic situation worsened, but nothing was ever done to prevent the congestion. Only after the Škorpikova Road/Ljubljanska Avenue interchange did the construction of the second roadway start. The bridge was finally completed in 2006, having four lanes complete with street lighting. The speed limit was lifted from to . The other part of road infrastructure Jankomir is well known for is the
Jankomir highway interchange on the Zagreb bypass. The motorways at Jankomir are maintained by
Hrvatske autoceste (HAC). The interchange connects
A2 and A3 highways with Ljubljanska Avenue. Because of the unusual layout of the modified
cloverleaf interchange, as it is formally described, motorists on the A3 have to take an exit to continue straight. This layout is in use due to the A3 formerly serving as a part of the Highway "Brotherhood and Unity" until the Croatian War of Independence. The interchange is a structure of utmost importance. With over 110,000 cars using the interchange daily, Jankomir interchange is the third-busiest interchange in Zagreb (with
Ivanja Reka and
Lučko interchange surpassing its traffic levels). A3 west of the interchange uses a faux
collector–distributor road scheme (the traffic flows don't converge back to A3 before the Jankomir interchange in the east) until the
Rakitje/
Ježdovec exit for the
Lučko Airport. On this stretch, the highway has 5 lanes going westbound and 4 lanes eastbound. Together with another collector–distributor system inside the interchange adding to this one, the interchange is often complex to navigate, some turns requiring the motorist to take up to 4 exit ramps to reach their destination, although the interchange makes up for this in extensive signage. Due to the collector–distributor systems gaining more total lanes in the interchange, jams on the exit ramps are extremely rare. == Geography and cityscape ==
