Lanes are available through the bridge modeler to indicate where vehicle loads act on a bridge superstructure. Lanes are defined by reference lines, which may be layout lines or frame-object paths. Versatile features enable the modeling of complex roadways and traffic patterns. Multiple lanes may be created, straight or curved, each of a specific length and width, and need not be parallel. Users may combine vehicle loads with static and dynamic loads, then envelope parameters for maximum and minimum response. Response quantities may then be presented in a useful manner according to lane geometry.

Tips
- As described in the Lane-to-object connection article, users may control which superstructure objects are subjected to lane loading.
