Shoreham Adur tidal walls scheme: reaches E1, E2 and E3

Updated 25 March 2019

E1: Tollhouse Bridge

At this reach there are new raised walls and flood gates.

A new combi-steel sheet-piled wall has been installed riverward of the existing defences along the majority of the frontage. The wall has been brick clad with flint panel insets, and new surfacing installed to complement the character of the conservation area. On the riverward side there are timber fenders to protect rivercraft and the piles.

The flood defences in this reach were installed using equipment working from a jack-up barge. A jack-up barge is a mobile platform for plant working in marine environments. It is fitted with long legs that can be raised or lowered. The legs are lowered to the seafloor to secure it in position, the legs are raised to allow it to be moved.

Construction started in this reach in 2016.

E2: Ropetackle

At this reach there is a new concrete wall and ramp. The wall provides flood protection at the rear of the existing footpath. This ties the new defences into the existing Ropetackle development and the Network Rail bridge abutment.

The construction of the new defences meant that the timber boardwalk had to be removed and reinstated on completion. Planting areas and seating were also replaced after the works were finished.

E3: Old Railway

Along this reach there is a steel sheet-piled wall, a concrete wall and an earth embankment.

From the rail bridge to the drainage ditch, a new steel sheet-piled wall has been built running along the rear of the existing footpath. At the drainage ditch, the wall becomes a reinforced concrete wall for 170m, then an earth embankment.

Work started in this reach in 2016. The northern section of this reach was completed and reopened to the public in December 2017. The southern section, between Ropetackle and the access to the Downs Link from the Old Shoreham Road, reopened after completion in 2018.
