Purpose: Used to indicate lanes are to be positioned laterally (between curbs) to determine live load envelopes in Girder System Projects using direct lane loading. (Not applicable to Line Girder Projects.)
--> Given in girder system input
Lanes are positioned laterally between curbs for maximum effect on the girder for which live load envelopes are being generated (see ROADWIDTH ).
