An arch will stand most force.
truss bridges are able to support the most weight applies to the bridge, especially when the weight is applied to the middle
I use Plastruct for modelling bridges.

A curved curtain rod with a flexible curtain would be best suited for an arch doorway to allow for easy opening and closing without obstructing the arch shape.

Compressive and tensile forces are present in all bridges, and it is the job of engineers to design bridges capable of withstanding these forces without buckling or snapping. Buckling occurs when compressive forces overcome an object's ability to handle compression, and snapping occurs when the tensile forces overcome an object's ability to handle tension. The best way to deal with these forces is to either dissipate them or transfer them. To dissipate force is to spread it out over a greater area, so that no one spot has to bear the brunt of the concentrated force. To transfer force is to move it from an area of weakness to an area of strength, an area designed to handle the force. An arch bridge is a good example of dissipation, while a suspension bridge is a good example of transference. Figures 6 and 7 illustrate tension and compression forces acting on three bridge types.
