    No they are not and never have been.

    The height of overhead stuff is also not the same state to state.Something oversize loads need to know when route planning.

    The Interstate Highway standards for the U.S. Interstate Highway System use a 12-foot (3.7 m) standard lane width, while narrower lanes are used on lower classification roads

    The widths of vehicle lanes typically vary from 2.7 to 4.6 m (9 to 15 ft). Depending on road ,traffic volume and type.

    It is common to have slightly wider lanes on curves.

    NO. I've seen lanes get smaller on freeways that have been "widened" to help traffic flow. Quite often, there's no room to actually widen the freeway, so they simply shrink the existing lanes and repaint the lines.

    No, the American Association of State Highway and Transportation Officials publishes standards that evaluate and advise when and how variations can be mitigated, but the recommendations have no binding authority.
