Cárdenas Ring Road

The Cárdenas Ring Road (Martino: Periférico de Cárdenas) are two circular ring roads (C55 and C56) encircling the city of Cárdenas, the capital of Nouvelle Alexandrie. It is part of the Pan-Keltian Highway and was opened between 1700 AN.

The motorway is a total of 120.6 km (75.4 mi) long, the Outer being 85.5 km (53.4 mi) long and the Inner being 35.1 (21.9 mi) km long, and is one of the busiest ring roads in the world. The system is designed to handle a peak capacity of 250,000 vehicles per day, with dynamic lane management and real-time traffic monitoring via a centralized control hub in the Utilities Sector.

The motorways feature a standard lane configuration with 3.5 m (11.5 ft) lane width, separated by a 1.2 m (4 ft) central central reservation with steel cable barriers and energy-absorbing W-beam guardrails. The pavement is made of Continuously reinforced concrete pavement, incorporating drainage layers and noise-reducing asphalt overlays.

History

The construction of Cárdenas was part of the synonymous Plan, which saw the new capital of the Federation of Nouvelle Alexandrie being constructed. The need for a ring road was deemed vital for the transportation needs. Both Roads were constructed between 1696 AN and 1700 AN. The C55, the Outer Ring, was connected to the C1 motorway and the C28A motorway, and acted as the main bulk road for the PKH. It follows a irregular circular path and is at a distance between 10 to 20 km (6 to 12 mi) from the city center. The C56, the Inner Ring, is a heavy-purpose ring road about 5 to 6.5 km (3 to 4 mi) from the city center, and is more circular. Both used multiple tunnels to bypass urban areas. The two rings were connected by link roads to the C1, north and west; and C28A, east.

Development beyond 1700 AN include: the opening of the Jario and Bagalipe Bypasses in 1708 AN and 1712 AN, respectively, which created two new south and east connections between the C55 and C56; the creation of the Olos Bypass in 1734 AN, creating a new southeast connection between C55 and C56; and the Badregas Orbital Highway, a half-circular far-out ring road to the east of Cárdenas, connecting between Ahuaco, Tastin, Bemar, and Jinozonte, bypassing the C56 at about 30 to 35 km (19 to 22 mi) from the city center.

Route

Outer Ring

The 0.0 mi point of the C55 is at the intersection with the C1 motorway, and its junctions are numbered clockwise. It moves circular (clockwise) past Conzalito, the Cárdenas Airport, Lagutepe, Ahuaco, Jario, Bemar, Jinozonte, Sicero-Izaran, Bagalipe, Nincaral, Tamento, Entertainment District, University District, Albaño, and the Military Sector.

The entire road is a four-lane dual carriageway, with safety barriers along the whole line and a hard shoulder. Between J1 and J9; and J22 and J29, the road is dual six-lane. The speed limit is 80 km/h (50 mph) throughout. There are speed cameras that enforce this limit.

Bridges and Tunnels

There are a total of 2 tunnels and 3 bridges: starting with the Conzalito bridge at 1.4 mi; the Airport-Harbor Tunnel at 8.5 mi; the Bemar Bridge at 25.4 mi; the Nincaral Bridge at 34.3 mi; and the Cardenas West Highway Tunnel at 42.4 mi (the longest tunnel in Nouvelle Alexandrie at 8.4 km/5.2 mi) - which includes a parallel service tunnel for maintenance and emergency evacuation, accessible every 500 meters via pressurized cross-passages.

Inner Ring

The 0.0 mi point of the C55 is at the C1-C56 Link, and its junctions are numbered clockwise. It moves circular (clockwise) through Science District, Banking Sector, Alanregal, Olos-San Ludo, Sicero-Izaran, Patiapa, Utilities District, Government District, and the Industry District.

The entire road is a six-lane dual carriageway, with a median strip and safety barriers. Most of the hard shoulder is on the median strip. Between J1 and J5; and J17 and J21, the road is dual eight-lane. The speed limit is 80 km/h (50 mph) throughout. There are speed cameras that enforce this limit.

Bridges and Tunnels

There are 4 tunnels: starting with the Banking Tunnel at 5.8 mi; the Olos Tunnel at 11.6 mi; the Patiapa Tunnel at 19.6 mi; and the Inner City Tunnel at 27.5 mi.

Badregas Orbital Highway

The 0.0 mi point of the BOH is at Puerta Aeropuerto, which was expanded into a full cloverleaf to create a new junction. It moves circular (clockwise) through Ahuaco, Jario, Bemar, Jinozonte, and finally ends at the Olos Bypass; at a mean distance of 14 km out from the Outer Ring.
