Short Span Steel Bridges 
Open Grid Decks
Open grid decks can be described as small-scale steel framing systems used as a bridge deck. They are made up of transverse sections to distribute the load across main rail members, providing strength to the decking system.
Open grid deck panels are used as an alternative to cast-in-place concrete decks. They provide a driving surface for traffic.

The connection between grid panels is made up of bolted or welded connections. Due to the possibility of fatigue issues, bolted connections are preferred. Bolted or weld connections can be used to connect the deck panels to the steel frame. Grouted shear connector pockets are another option for this connection detail. Generally, when steel guard rails are to be mounted on the deck panels, bolted connections are used
These decks are beneficial for situations where lightweight decks are required, such as movable bridges and suspension bridges.
What is a bridge deck?
The decking system of a bridge can be defined as the surface upon which the traversing traffic drives. This is the surface which is used as a continuation of the driving surface on either side of the bridge.
Commonly, cast-in-place concrete is used as the method of placing a deck on a short span bridge, but due to the time of preparing formwork, it can be a very time-consuming process.
Prefabricated deck systems are some of the most commonly used applications of modular bridge technology.
