The 7,578-foot-long (2,310 m) floating span consisted of 33 pontoons and cost $24.7 million to construct (equivalent to $254 million in 2025); [4] the bridge carried four lanes of traffic, separated by a curb that was later replaced with a simple Jersey barrier; at the center was a drawspan that opened for large vessels traversing the lake.
A grid deck uses beams and diaphragms as the supporting structure. The supporting system of a grid deck is analyzed using a grillage analysis. A slab deck is one where the deck is analyzed as a plate. If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck.
A deck is also the surface used to construct a boardwalk over sand on barrier islands. Laying deck or throwing deck refers to the act of placing and bolting down cold-formed steel beneath roofing and concrete floors. This is usually done by an ironworker, sometimes in conjunction with a cement mason or carpenter. It regarded as one of the most ...
The main function of an OWSJ is to provide direct support for roof or floor deck and to transfer the load imposed on the deck to the structural frame i.e. beam and column. In order to accurately design an OWSJ, engineers consider the joist span between bearing points, joist spacing, slope, live loads , dead loads , collateral loads, seismic ...
Around fifty of this type of linkspan have been built. The design allowed flexibility for ship-owners and ports during the changeover from the old very restricting system. With the development of wider ship's ramps (up to 28 m or 92 ft), triple lane lower deck and two lane upper-deck accesses to vessels, the submerged tank type has been superseded.
The bridging component involved an assault bridge, designed by Major Charles Inglis RE, the Canal Lock Bridge, which had sufficient length to span a canal lock. Major Martel mated the bridge with the tank and used hydraulic power generated by the tank's engine to manoeuvre the bridge into place.
The deck includes any road lanes, medians, sidewalks, parapets or railings, and miscellaneous items like drainage and lighting. The supporting structure consists of the steel or concrete system supporting the deck. This includes the girders themselves, diaphragms or cross-braces, and (if applicable) the truss or arch system.
