CV-820 Road Safety and Heritage Bridge, Agost–Maigmó Greenway (Alicante)
EXECUTON PERIOD
TOTAL INVESTMENT OF THE WORKS (VAT INCLUDED)
Background
The project area was located along the CV‑820 road between KP 8+850 and KP 9+240, and at the intersection with the overpass of the Agost–Maigmó Greenway.
The CV‑820 road formed part of the Local Autonomous Road Network of the Generalitat Valenciana, connecting the towns of Agost and Novelda. It consisted of a single carriageway with two traffic lanes, one in each direction, with a total width of 9.00 metres including the shoulders.
The works were carried out both on the CV‑820 road itself and on the overpass of the Agost–Maigmó Greenway.
Scope of works
- - Address the road safety issue present on the CV‑820 road, approximately at KP 9+150, caused by the existing carriageway narrowing.
- - Ensure adequate protection for cyclists at this singular point, given that the CV‑820 between Agost and Novelda was designated as a “Safe Cycling Route”.
- - Provide a cycling connection from the Agost–Maigmó Greenway to the town of Agost, running parallel to the CV‑820 road.
The intervention followed regional road safety guidelines applied across the entire autonomous road network.
The project’s standout feature: a 1916 riveted steel bridge from the original TRAM Line L1, decommissioned during modernisation and stored in Teulada. Rather than being lost, this piece of industrial heritage was given a second life.
The original low-clearance abutments were demolished and rebuilt to original typology — a heritage inventory informed every decision — on the CV‑820 road, which created a narrow and low‑visibility section due to its clearance. The abutments were rebuilt following their original typology and after a prior heritage inventory, in order to accommodate the length of the new structure.
The structure was transported from Teulada, sandblasted, repaired (particularly gusset plates) and fitted with the internal pedestrian walkway substructure.
The works also reinstated two pressurised irrigation pipelines along the outer sides of the structure, and connected the Agost access and the bridge into the Agost–Maigmó Greenway (Alcoy–Monforte del Cid railway corridor) through a new access ramp on the southern side.
