A7 (Croatia)
The A7 motorway is a motorway in Croatia. It connects the nation's largest port in Rijeka, to the Croatian motorway network, as well as to the Rupa and Pasjak border crossings to Slovenia. The motorway forms part of a transportation corridor in Croatia, and it is a part of European route E61 Villach-Ljubljana-Trieste-Rijeka. The A7 motorway route south of Orehovica interchange, where it also intersects Pan-European corridor Vb, is a part of European route E65.
The A7 motorway runs near a number of Croatian cities and provides access to Učka Nature Park and, indirectly, to numerous resorts in the Istria and Kvarner Gulf regions. The motorway is nationally significant because of its positive economic impact on the cities and towns it connects, and because of its contribution to tourism in Croatia. The importance of the motorway as a transit route will be further increased upon completion of a proposed expansion of the Port of Rijeka and Rijeka transport node.
The motorway consists of two traffic lanes and an emergency lane in each driving direction, separated by a central reservation. There are no emergency lanes in the tunnels. All intersections of the A7 motorway are grade separated. Numerous bridges, viaducts, tunnels, and other structures were required as the route traverses rugged terrain. As of 2010, there are ten exits and two rest areas situated along the route. Most of the motorway is not tolled, but a single section is tolled using an open toll system with pricing tied to vehicle classification.
Plans for the motorway were officially formulated in 1974 and the construction was started in 1977. The first sections were completed as a two-lane expressway with grade-separated intersections, in 1988 and 1990, comprising the western arm of Rijeka bypass. As the first stage of the A6 motorway construction spanning between Zagreb and Rijeka neared completion in the 2000s, construction of a proper motorway along the A7 route started. In December 2009, the Diračje-Orehovica section was upgraded to a six-lane motorway, bringing the entire route between Rupa border crossing and Sveti Kuzam interchange to a uniform standard.
Two new sections of the A7 motorway are currently under construction, extending the route eastward into vicinity of Kraljevica, Crikvenica, and Krk Bridge. The two sections are scheduled to be completed by 2012. Current long-term plans for developing the A7 motorway define its ultimate southern terminus in Žuta Lokva at the interchange of the A1 motorway. This section is no longer part of any short-term plans, as no funding until 2012 is currently scheduled for the section. Further long term plans specify an outer Rijeka bypass and a new interchange with the A8 expressway.
Route description
The A7 motorway is an important north-south motorway in western Croatia, connecting the nation's largest port and the city of Rijeka to the Slovenian road network at the Rupa border crossing. The A7 motorway currently connects to the rest of the Croatian motorway network via the A6 motorway in Orehovica interchange. The motorway is a part of International E-road network routes E65 and E61. The sections south of Orehovica interchange are a part of the E65, while the remaining sections are a part of the E61.The motorway is of major importance to Croatia in terms of its development of the economy of Croatia, most notably in tourism, as it represents the shortest and the most convenient route between Trieste, Italy or Ljubljana, Slovenia and the Adriatic Sea. This particularly applies to tourist resorts in the Kvarner Gulf area and to the Port of Rijeka, but it is also true for resorts in Istria, served via the A8 expressway. The genuine importance of the motorway as a transit route will be demonstrated upon completion of the A7 route to Žuta Lokva interchange of the A1 motorway and proposed expansion of the Port of Rijeka and Rijeka transport node. The former is planned as a part of completion of the Adriatic-Ionian motorway, while the latter is planned to encompass the growth of the Port of Rijeka's cargo handling capacity, improved railroad links and a new Rijeka bypass motorway linking the A7, via a number of new interchanges, to the A6 and A8 motorways. The project is, among other goals, aiming to increase traffic along the Croatian part of Pan-European corridor Vb, which connects to the A7 near Rijeka.
, the motorway spans between the Rupa border crossing to Slovenia and Križišće where southbound A7 traffic currently ends at a roundabout connecting to the state roads D8 and D102. It connects to Rijeka as it forms Rijeka bypass, the A8 expressway of the Istrian Y and the A6 which represents motorway connection to Zagreb and Split. Future development of the motorway will include southward extensions of the motorway towards Crikvenica, Novi Vinodolski, Senj, and ultimately Žuta Lokva interchange on the A1 motorway. The A7 motorway consists of two traffic lanes and an emergency lane in each driving direction along its entire length, except in tunnels where there are emergency bays rather than lanes. All existing interchanges are trumpet interchanges. There are two rest areas along the motorway, providing various types of services ranging from parking spaces and restrooms to filling stations and restaurants. As of October 2010, the motorway has 10 interchanges, providing access to a number of towns and cities and to the Croatian state road network. The motorway is operated by Autocesta Rijeka - Zagreb.
An automatic traffic monitoring and guidance system is in place along the motorway. It consists of measuring, control, and signaling devices, located in zones where driving conditions may vary—at interchanges, near viaducts, beside bridges, in tunnels, and in zones where fog and strong winds are known to occur. The system consists of variable traffic signs used to communicate changing driving conditions, possible restrictions, and other information to motorway users.
The A7 motorway runs through hills, rugged coastal terrain, and urban areas, requiring a substantial number of bridges, viaducts, and tunnels along the route. Particular attention to the environment is also required since the route is situated in karst topography, which is particularly susceptible to water pollution, and the urbanized areas requiring special attention to be paid to noise pollution. Noise pollution was assessed as especially severe in the Rastočine neighborhood of Rijeka, where residential buildings are particularly close to the motorway route, most notably a 26 story high-rise only away from the route. The noise pollution was addressed by building a noise barrier long which largely encloses that motorway section like a tunnel. Curved overhead sections of the noise barrier are covered with of solar panels with annual electricity production capacity of 248,000 kWh.
Toll
Only one section of the A7 motorway is tolled based on the vehicle classification in Croatia using an open toll system in place between the Rupa and Jurdani interchanges. The toll is payable in Croatian kuna, euros, and major credit and debit cards. A number of prepaid toll collection systems are also used, including various types of smart cards issued by the motorway operator and ENC—an electronic toll collection system which is shared by most motorways in Croatia and provides drivers with discounted toll rates for dedicated lanes at toll plazas.As of December 2010, Autocesta Rijeka-Zagreb collects toll on a single section of the motorway, between Rupa and Jurdani interchanges, close to the northern terminus of the motorway. Unlike those sections further south, which are used as bypass road of the city of Rijeka, therefore carrying substantial suburban and commuter traffic, the tolled section carries almost exclusively transit traffic. The Rupa toll plaza, located on the section reported 240,975 kuna collected during a single, peak season, weekend in July. Even though motorway traffic volume and thus toll revenue, decreased slightly elsewhere in the country, this particular tolled section reported virtually no change in income by 2010.
Notable structures
As the A7 motorway route runs through rugged terrain, it utilizes a substantial number of major structures—bridges, viaducts, tunnels, underpasses, flyovers, and culverts. A significant number of interchanges present along Rijeka bypass the A7 section between Matulji and Sveti Kuzam which consists of seven interchanges, thus yielding an average distance of only between them.The longest structures on the A7 motorway are the Trsat Tunnel located on the Orehovica interchange-Škurinje section, the Škurinje II Tunnel situated between Škurinje and Rujevica exits, and the Vežica Viaduct built on Orehovica-Draga section of the motorway. Rječina Bridge, a inclined strut reinforced concrete bridge spanning the Rječina River canyon, is also noteworthy because its design and construction conditions are different from normal since it spans a protected water supply zone. The bridge consists of two parallel structures, and the first one to be completed was the northern span in 1984. The southern span was the last structure completed on the present A7 motorway route, and it was opened to traffic in 2009, 25 years after the original span.
History
Rijeka bypass
Development of the city of Rijeka and the surrounding region, associated transit transport of cargo, tourism and associated passenger traffic to the northern Adriatic resorts, rugged coastal topography, and the existing road routes running through the city of Rijeka itself, necessitated development of a high capacity bypass road to further the development and relieve congestion on the city streets. This was first officially formulated in spatial planning documents in 1974, and construction started in 1977. The first, section was completed in July 1988, between Diračje and Orehovica interchange, executed as a two-lane expressway with grade separated intersections. The Diračje-Matulji and Matulji-Jušići sections, completed in 1990 and 1991 respectively, were built as four-lane expressways without emergency lanes. Those completed the western arm of Rijeka bypass, but traffic proceeding east from Orehovica interchange to Krk Island, Crikvenica, and Senj still had to switch to streets of Rijeka.Modern motorway
In the 2000s, as the first stage of the A6 motorway construction spanning between Zagreb and Rijeka neared completion, construction of a proper motorway along the A7 route started. In 2004, when the first stage of Rijeka-Zagreb motorway was completed, the A7 route was extended by to Jurdani, and in 2005, another section was completed between Jurdani and the Slovenian border. The two new sections were the first ones built as a six-lane motorway. In May 2006, the motorway extended east to Sveti Kuzam, forming the eastern arm of Rijeka bypass, relieving that part of the city from the transit traffic. Finally, after the Rijeka-Zagreb motorway was completed in 2008, the works on the remaining single-carriageway section of the route intensified. In December 2009, the Diračje-Orehovica section was upgraded to six-lane motorway, thus bringing the entire route between Rupa border crossing and Sveti Kuzam interchange to a uniform standard.Even though Hrvatske autoceste normally develops motorways in Croatia, as of September 2007, Autocesta Rijeka - Zagreb was granted expansion of the concession previously awarded. The new concession contract included development and maintenance of the A7 motorway north of Križišće interchange, Krk Bridge, and a number of motorway access roads. At the same time, the concession period was extended to 32 years and 11 months, starting on the date of the original concession contract. Therefore, the concession, in its present form, will expire on May 28, 2031. Construction costs incurred after 2007, when Autocesta Rijeka - Zagreb took over the motorway development, were estimated at 105 million euros.
Future
Long-term plans of development of the A7 motorway, published in the 2000s, involved an extension of the southern terminus to the interchange with the A1 motorway at Žuta Lokva. The section between Križišće and the Žuta Lokva was initially planned to be opened as an expressway by 2009, but those plans have been put on hold and the section is no longer included in any short-term plans, as no funding is going to be appropriated for it until 2012. In 2012, Croatian government announced that no funds shall be made available in near future for construction of A7 south of Križišće.Further long term plans specify an outer Rijeka bypass which is planned on the route Jurdani-Marčelji-Kikovica-Kraljevica, and it would be wider and longer. Similarly, a new interchange of the A8 and A7 motorways is planned near Jušići; however, these long-term plans, even though they are well documented in government studies, still have no funding approved.
Traffic volume
Traffic is regularly counted by means of a traffic census at Rupa mainline toll plaza as well as at two other sections of the motorway which are not tolled. The traffic volume is reported by Autocesta Rijeka - Zagreb, the operator of the motorway, and are published by Hrvatske ceste. The traffic is the heaviest along the western arm of Rijeka bypass as the section serves the city and acts as a link between the A8 and the A6 motorways while carrying regular A7 traffic. That part of the A7 motorway carries a 20,100-vehicle annual average daily traffic, and a 31,700-vehicle average summer daily traffic figure.Substantial variations observed between AADT and ASDT are normally attributed to the fact that the motorway carries significant tourist traffic to Istria and Kvarner Gulf area. The seasonal increase in traffic volume ranges from 10% on the south of Oštrovica interchange to 120% as measured on the Rupa-Matulji section. The central part of the motorway exhibits summer-season traffic volume increase of approximately 50%.
Rest areas
As of November 2010, there are only two rest areas operating along the A7 motorway. Applicable legislation provides for four types of rest areas designated as types A through D: A-type rest areas comprise a full range of amenities including a filling station, a restaurant, and a hotel or motel; B-type rest areas have no lodging; C-type rest areas are very common and include a filling station and a café but no restaurants or accommodations; and D-type rest areas offer parking spaces only, with possibly some picnic tables, benches, and restrooms. Even though the rest areas found along the A7 motorway follow this ranking system, the Vrata Jadrana rest area is a C-type rest area and the Rupa rest area is a B-type facility. The filling stations also offer LPG fuel and include small convenience stores.The primary motorway operator, Autocesta Rijeka-Zagreb, leases the rest areas to various operators through public tenders. As of November 2010, both rest areas found along the A7 motorway are operated by OMV. The rest area operators are not permitted to sub-lease the fuel operations, but they are also penalized if some facilities required by the lease contract are not operating. All of the A7 motorway rest areas, are accessible from both traffic directions of the motorway. The rest areas normally operate 24 hours a day, seven days a week.
