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.
Exhibit 7-3 in the Green Book describes minimum lane widths for two-lane rural highways for a range of design speeds and design-year traffic. The table entries show a 24-foot traveled way (12-foot lanes) for most conditions.
