Is the lateral startup force considered in bridge design?

You might post this at one of the other boards. We do have some active and retired railroad design and Bridge & Building folks here, but I doubt if they would see your post on this Railfan board.

Not familiar with the term.  If you mean longitudinal force (caused by braking or accelerating a vehicle on the bridge), then there are standards usually expressed as a percentage of live load.  15% or 20% are common allowances.  See the Wisconsin DOT Bridge Manual, Chapter 38, p. 15, for example (available online at https://wisconsindot.gov/dtsdmanuals/strct/manuals/bridge/ch38.pdf).  Or the AREMA Manual, Chapter 15 (Steel Structures).
