An accrual policy is one where employees earn sick leave over time, with the accrued time carrying over in each year of employment. In general terms (and subject to some exceptions), employees under an accrual plan must earn at least one hour of paid sick leave for each 30 hours of work (the 1:30 schedule).
The most important routes could be anything up to 60 feet (18 m) wide, enough for a full, wide, modern dual carriageway! These great widths can still be seen, even though the modern surfaced roads may only be 5 or 6 m wide, they lie between wide grass verges, showing the original width of the road.
There are currently 8,614,790 lane miles of road in the lower 48 states. The average width of a highway lane is 11 feet. This means roads cover 17,947 square miles of land, or just six-tenths of 1 percent of the total land area of the contiguous 48 states.
