{{jct|country=HRV|A|9}} |type= |const= |opened= |height= |maint=[BINA Istra](/source/BINA_Istra) |tolls=Closed toll collection system |map= }} The '''Istrian Y''' ({{langx|hr|Istarski ipsilon}}) is a [highway](/source/highway) network in the [Croatian highway network](/source/Highways_in_Croatia) & [TEN-T](/source/Trans-European_Transport_Network) network, maintained by [BINA Istra](/source/BINA_Istra) (from 1995 through at least 2027). It consists of two sections arranged in a shape similar to the letter ''Y'', located in [Istria County](/source/Istria_County): *{{jct|A|8|country=HRV}} ([Matulji](/source/Matulji) – [Kanfanar](/source/Kanfanar_interchange)) *{{jct|A|9|country=HRV}} ([Plovanija](/source/Slovenia) – [Pula](/source/Pula) via Kanfanar) == Eastern branch == {{main|A8 (Croatia)}} The A8 is a {{convert|64.21|km|mi|abbr=on}} long branch which starts at [Matulji](/source/Matulji) in [Primorje-Gorski Kotar County](/source/Primorje-Gorski_Kotar_County) and finishes in [Kanfanar interchange](/source/Kanfanar_interchange), at the crossing with the A9. The branch was initially built as a single carriageway [limited-access road](/source/limited-access_road), but the part between Kanfanar and [Pazin](/source/Pazin) was projected as a [dual carriageway](/source/dual_carriageway), so all the objects on the road are already prepared for a conversion to a motorway. The most prominent feature of this branch of Istrian Y is the {{convert|5.4|km|mi|abbr=on}} long [Učka Tunnel](/source/U%C4%8Dka_Tunnel), the third longest tunnel in Croatia. The tunnel was opened in 1981 and is the main road that connects the [Istrian peninsula](/source/Istria) with [Rijeka](/source/Rijeka) and the rest of Croatia (and the only road for vehicles over 5 tonnes). The tunnel is tolled within a [closed toll collection system](/source/Closed_toll_collection) with the rest of the network. The first part opened as full motorway, from Kanfanar to Rogovići, was opened for traffic in 2011. Then, sections between Rogovići - Cerovlje, Cerovlje - Lupoglav, and Lupoglav - Vranja, opened in consecutive years from 2020. == Western branch == {{main|A9 (Croatia)}} The A9 is a {{convert|76.79|km|mi|abbr=on}} long branch which connects the [Croatia](/source/Croatia)n-[Slovenia](/source/Slovenia)n border near [Sečovlje](/source/Se%C4%8Dovlje) with the city of [Pula](/source/Pula) and services the tourist industry on the western coast of Istria. Motorway was initially built as single carriageway [limited-access](/source/limited-access_road) road. There are two prominent object on this branch of Istrian Y: the [viaduct](/source/viaduct) "Limska draga" and the [bridge](/source/bridge) "Mirna". The viaduct "Limska draga" was built between 1988 and 1991 and was the first part of the western branch of Istrian Y that was constructed. The bridge is 552 m long and the height of the highest pillon is 120 m. The bridge "Mirna" was opened to traffic in 2005. The bridge represents the crossing over river [Mirna](/source/Mirna_River_(Croatia)) and was the most complicated object on the western branch of the Istrian Y because of the swampy terrain around the river. The bridge is 1355 m long and the height of the bridge at the highest point is 40 m. Currently the bridge is being tolled at the price of 14 [HRK](/source/Croatian_kuna) for passenger cars. The southern leg of A9 motorway, between Kanfanar and Pula was opened as motorway for traffic in 2010. The northern leg of the A9 motorway, 50 km from [Umag](/source/Umag) to [Kanfanar](/source/Kanfanar), was opened as motorway for traffic on 14 June 2011, eight months before the deadline.{{cite web|url=http://www.ezadar.hr/clanak/kosor-otvorila-puni-profil-autoceste-na-istarskom-ipsilonu-od-kanfanara-do-umaga|title=Kosor otvorila puni profil autoceste na Istarskom ipsilonu od Kanfanara do Umaga|date=14 June 2011|language=Croatian|accessdate=15 June 2011}}{{cite web|url=http://regionalexpress.hr/site/more/sveano-otvorena-dionica-autoceste-umag-kanfanar/|title=Svečano otvorena dionica autoceste Umag – Kanfanar | work=Regional Express - online magazin|date=14 June 2011|language=Croatian|accessdate=15 June 2011}} == Upgrade == The network is undergoing extensive upgrade & refurbishment works{{Cite web |title=State Aid SA.56832 (2020/N) – Croatia – Sixth amendment to the concession agreement relating to the Istrian Y Motorway (sub-phase 2B2-1: section Vranja Interchange to the Učka tunnel/Kvarner portal) |url=https://ec.europa.eu/competition/state_aid/cases1/202040/286936_2193817_132_2.pdf |url-status=live |archive-url=https://web.archive.org/web/20230809204509/https://ec.europa.eu/competition/state_aid/cases1/202040/286936_2193817_132_2.pdf |archive-date=2023-08-09 |access-date=2023-08-09}}.
