Royal Victoria Dock Footbridge
The Royal Victoria Dock (RVD) Footbridge located within the Royal Victoria Docks between Custom House and Silvertown, East London.
The Royal Victoria Dock Footbridge is a slender light weight single span steel footbridge with an elevated suspended timber deck. It comprises a combination of main, secondary and tertiary masts located along the longitudinal centre line of the deck supporting the suspension backstay and forestay cables. The main masts at each end are approximately 100m apart and located above the main pair of support columns, which are founded on reinforced concrete piled foundations. Access to the elevated deck is via two lifts or a single stair located at each end of the footbridge. The structure was constructed in 2000.
Connaught Footbridge
The Connaught Footbridge located within the Royal Victoria Docks between Custom House and Silvertown, East London.
The Footbridge is a single span twin leaf steel box cantilever bridge located within the Royal Docks in East London which carries unnamed pedestrian footway over a narrow stretch of the docks connecting the Royal Victoria to the Royal Albert docks. It runs parallel to the larger Connaught Road Bridge adjacent directly to the east. The bridge consists of 2No cantilevered steel box wings tapering from either bank and meeting at midspan. Each leaf of the structure is mounted on a steel pinion wheel support which allows the leaves to be rotated through 90 degrees to allow the passage of ships from one dock to the other. Two concrete approach ramps lead up to the structure and house the mechanical and electrical elements required to swing the bridge. The structure was completed in 1990.
The structure has a clear span of 32.9m with a 3.16m wide footway measured from parapet centreline to centreline. The main tapered box section is 2m wide with a constant 200mm deep cantilever section on each side. The headroom at midspan is approximately 2.91m (dependent on fluctuating water levels).
Connaught Road bridge
The Connaught Road Bridge located within the Royal Victoria Docks between Custom House and Silvertown, East London.
The original Connaught swing bridge was built in 1904. At this time the bridge was carrying both the North Woolwich Railway and the Connaught Road access across the channel between the Royal Albert and Royal Victoria Docks.
The present Connaught Road Bridge is a cable stayed swing bridge with reinforced concrete approach viaducts located within the Royal Docks in East London. It carries a two-lane dual carriageway road over a narrow stretch of the docks connecting the Royal Victoria Dock to the Royal Albert Dock. It runs parallel to the smaller Connaught Footbridge adjacent directly to the west.
The steel bridge consists of 2No parallel continuous tapered steel box sections with internal diaphragms extending in both directions from a central pinion column (which houses the mechanical and electrical elements required to swing the bridge). Sleeved cable stays extend from a control tower above the pinion supporting the box section which cantilevers in both directions. This section of the structure can be rotated through 90 degrees to allow the passage of ships from one dock to the other.
Approach viaducts on both sides consist of continuous reinforced concrete beams supported on bearings atop a series of circular reinforced concrete piers on piles. The structure was completed circa 1990.
The swing section dock and tail spans are approximately 50m and 24.7m respectively. The steel box sections are approx. 2.28m deep at their deepest and 10.1m wide (including winged part). The approach viaduct spans are approximately 30m.
The dual lane carriageway is 7.3m wide with a 3.4m kerbed central reservation/walkway and 1.1m kerbed sides protected by 1m high vehicle restraint barrier. 1.2m width of the central reservation consists of a metal mesh walkway spanning between the box sections either side. The 1m high VRS consist of upright posts connected by 3No steel horizontals with mesh infill
Bascule Bridge
The King George V Bascule Bridge located within the Royal Victoria Docks between Beckton and North Woolwich, East London.
The King George V Bascule Bridge is a single span road bridge. It carries Woolwich Manor Way (a two-lane single carriageway road with a pedestrian footway separated from the road by way of a low concrete kerb) over a narrow stretch of the Royal Docks between the River Thames and King George V dock, adjacent to the King George V lock.
The bridge consists of 2No cantilevered steel box girder leaves which taper towards and meet at mid span. These girders are stiffened both transversely and longitudinally and separated into several compartments by internal diaphragms. Each leaf can be raised through approximately 90 degrees by way of a mechanical drive to allow the passage of tall marine vessels.
The bridge mechanical drive, hydraulics and electronics systems are located in brickwork ‘control houses’ at the span ends. These pre-exist the current bridge and formed part of a previous structure. The pedestrian footways are supported on propped cantilever steel decking welded to the main box sections. Concrete approach ramps lead up to the steel part of the deck. The ramps consist of prestressed M-beams and reinforced concrete slab.
Each box girder leaf is 26.5m long and made up of a 6.8m tail span and 19.7m main span. The carriageway is 7.3m wide and each footway is 2.7m wide. In its closed state, approximately 5.2m of headroom is provided (subject to fluctuating water levels). The structure in its current state was completed in 1990.
