A11 (Croatia)

After several delays attributed to planning and land ownership issues, as well as funding and lack of political support, the first section of the A11 was opened in 2009, just 9 kilometres (5.6 miles) long.

As of January 2016, 30 kilometres (19 miles) of the route are open to traffic, connecting the D31 and the D30 roads at Velika Gorica and Poljana Lekenička exits respectively.

The system uses variable traffic signs to communicate changing driving conditions, possible restrictions and other information to motorway users.

[4] The A11 motorway mainly runs through a plain, south of Sava River, requiring no major structures except for the exit interchanges themselves.

The plan also required moving the A3 motorway Buzin interchange approximately 2.5 kilometres (1.6 miles) to the west.

[7] In February and March 2006, Government of Croatia performed tender procedure for the 8.3-kilometre (5.2 mi) northernmost section of the A11 spanning the Jakuševec interchange and the Velika Gorica jug exit.

[8] On April 4, commencement of the works between the Velika Gorica jug interchange and Hrašće Turopoljsko was announced.

[9] The first indication of delays came in March 2007, when the national government started trading accusations with authorities of the Zagreb County.

[10] This situation led to announcements made in 2008, that the motorway would be built from the direction of Sisak, however that was not immediately feasible as land was not purchased and construction design had to be adjusted.

The section is 9 kilometres (5.6 miles) long, and contains 6 bridges, 4 flyovers, 2 wildlife crossings, a viaduct and an underpass.

The company which operates both of the motorways claimed that the average price of the A1 motorway was 7.1 million euro per kilometer and that the average cost per kilometer of the A11 stands at 11.3 million euro, further citing high transport cost of the backfill material caused by remote location of the closest quarry which is approximately 100 kilometres (62 miles) away.

The section required construction of two bridges, six flyovers, four culverts, Lekenik toll plaza and Peščenica rest area.

[21][20] The subsection was opened for traffic in April 2015, and the cost was 700 million kuna (about 95 million euro), excluding VAT, and was to date the most expensive motorway ever built by Croatian Motorways Ltd.[22] The 11-kilometre (6.8 mi) Jakuševec–Velika Gorica jug section of the A11 spans Zagreb suburban area and its completion was repeatedly delayed due to changes of legislation, land acquisition and funding issues.

[13][23][6] In November 2015, that section of the motorway was opened, connecting the Jakuševec and Velika Gorica jug interchanges, at a total cost of 1.645 billion kuna (222.2 million euro).

[25] The future access road to the A11 from the direction of Zagreb via the Sarajevska street and onto the Jakuševec interchange will require a large overpass to span the width of the Croatian Railways marshalling station located there, and as of 2015 preparatory investments were being made.
