How can I apply two traffic lanes over a 5 pan bridge?

Two traffic lanes needs to be applied over a 5-span bridge with variable geometry.

 6 different lanes are used at the moment. Lane factors applied to each lane are not visible..How can I apply two traffic lanes over a 5 pan bridge?

The lanes have changed as follows. 

I would suggest you to create the beam element of dummy property  and provide that elements on location of traffic line lane as part of grillage.

After creating these elements, use the elements to create the traffic line lane with eccentricity zero and provide start and end skew angles.

Note: Add that newly created elements to structure group and activate these elements in construction stages (CS1).

A video for lane 1 has been attached for reference and provide the skew angles
