English: The sun sets as ISAF troops in a Husky Armoured Vehicle pass Afghan locals on Route Trident in Helmand, Afghanistan.

This phase of Route Trident has seen 9 Parachute Squadron 23 Engineer Regiment tackle a challenging piece of terrain known as the “Culvert of Doom” close to the Patrol base Nahidullah.

The road is being solidly constructed using carpet-like membranes, tough plastic neo cells and high quality aggregates and stone, which should hold together well despite heavy vehicles and harsh weather conditions. Local people themselves are being employed to carry out some of the work which brings welcome cash into the area's economy.

Then engineers have heavily committed to an operation to build across the Loy Mandeh. In the clear phase, the combat engineers provided explosive breaching to enable 2 Scots to break into insurgent strongholds. Holding work included the reinforcing of compounds, and the construction of Sangers. Route Trident is now being extended across the Mandeh. The terrain is harsh and challenging; plenty of airborne initiative has been required.
