D21 was an 80.1-kilometre-long (49.8 mi), north–south

state road in Istria County, Croatia. A short section of D21 was part of the European route E751. The northern terminus of the route was located at the Croatia–Slovenia border at the Dragonja River. There it connected to Koper, Slovenia, and Trieste, Italy, via the Slovene route G11 further north. The route was generally parallel to A9 motorway, with which it formed several junctions, either directly or via short connectors, at Buje, Bale and Vodnjan – towns served directly by D21. The southern terminus of the route was found in the city of Pula, at the southern tip of the Istrian
Peninsula.

The road, as well as all other state roads in Croatia, was managed and maintained by Hrvatske ceste, a state-owned company. The road carried an annual average daily traffic of about 2,000 vehicles, and the traffic volume increased by up to 1,000 vehicles in summer as the road was used by tourists in the region. The southernmost portion of the road was significantly more congested as it carries Pula suburban traffic.

In

Second World War. It was made a separate state road and assigned the D21 route number in 1997. In 2013, the road was abolished because of the creation of parallel D75 road, located west of the A9 motorway.[1][2]

Route description

D21 road (facing north) at the Ž5042 junction near Višnjan

D21 was an 80.1-kilometre (49.8 mi)

Bale and Baderna, where the road was predominantly surrounded by forests. The southernmost 2.2 kilometres (1.4 miles) of the route ran through suburbs of Pula – the largest city in the region. D21 extended south from the Kaštel border crossing between Croatia and Slovenia situated at the Dragonja River.[3] To the north of the D21 terminus, the route – a part of the European route E751 – connected the cities of Koper, Slovenia,[4] and Trieste, Italy, via G11 in Slovenia.[5][6]

The first section of the D21 route followed an overall eastern orientation. About 400 metres (1,300 feet) away from the borderline, it reaches the Kaštel border crossing, and after 800 metres (2,600 feet), there is an

D510, which serves as a connector to the A9 motorway. D21 itself turns southwest towards the village of Kaštel, approximately two kilometres (1.2 mi) away.[7]

Just to the north of Kaštel, D21 turned south before proceeding to the town of

D301 which links the town of Novigrad and another A9 interchange to the west.[8]

After the route crossed the Mirna River, it continued about six kilometres (3.7 mi) southeast to Vižinada, where D21 forms an intersection with Ž5041 county road to Kaštelir and Poreč. After Vižinada, the route continued another five kilometres (3.1 mi) south, where it reached the Ž5042 intersection connecting Višnjan. Approximately nine kilometres (5.6 mi) south, at Baderna, D21 connects with D302 extending to Poreč and the A9 motorway, located west of the road junction, as well as D48 leading to Pazin east of D21. The intersection is built as a partial cloverleaf interchange.[9]

Approximately four kilometres (2.5 mi) south of Baderna, the route reached the village of

D303. D303, in turn, links to the Kanfanar interchange of the A9 motorway and the coastal city of Rovinj.[10]

South of the D303 intersection, D21 ran south along a generally flat terrain and consisted of relatively straight sections compared to the northern parts of the route. About six kilometres (3.7 mi) south of the D303 junction, D21 formed an at-grade intersection with Ž5098 to Svetvinčenat. Three kilometres (1.9 mi) from there, D21 entered Bale and intersected the Ž5096 road connecting Rovinj to the northwest. South of Bale, D21 turns southeast and approaches Vodnjan. It reaches a short connector to the Vodnjan-sjever (north) interchange of the A9 motorway eight kilometres (5.0 mi) down the road.[11]

After another two kilometres (1.2 mi), D21 reached Vodnjan and the Ž5192 road junction connecting to

D400.[13]

History

Pula, the southern extent of D21 route

In

Tarsatica – modern-day Trsat area of the city of Rijeka.[14]

Following the

paving of the Trieste–Pula road in 1930s.[15]

During the

SFR Yugoslavia,[16] signposted as M2 route.[17] The next major addition to the road network on the peninsula was completion of the first section of the Istrian Y expressway in 1981. The system was designed to replace M2 route as the main road route in Istria.[18] The Yugoslav M2 designation was retained after the independence of Croatia, until 1997, when the part of the Adriatic Highway spanning the Slovene border and Pula was designated as state road D21.[19] Since October 1991, Hrvatske ceste, a company owned by the Government of Croatia, has been tasked with maintenance of the road.[20] In 2013, following a new classification, the coastal county roads were classified as D75 state road and thus, D21 lost on its importance and was declassified. The present-day route of the D21 consist of short, one kilometre (0.62 mi) section of D510, 45.8-kilometre (28.5 mi) section of Ž5209 county road, forming its northern half and 32.7-kilometre (20.3 mi) section of D75, forming its southern half.[21]

Traffic volume

Volume of traffic flowing along D21 road was measured by Hrvatske ceste at six traffic counting stations distributed along the route. Three of the traffic counting stations work continuously, while the rest of them are operated intermittently. By 2002, the road lost a significant portion of its north–south traffic as A9 motorway was gradually extended since 1991,[18] running parallel to the route. At the Kaštel traffic counting site, the average summer traffic volume declined from 12,564 vehicles per day recorded in 2002, to just 2,989 vehicles in 2011.[22][23]

Major intersections

The entire route is in Istria County.
