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.
Flexibility is also evident for lower-class roads and streets, with recommended narrower lane widths consistent with lower design speeds on such roads. The discussion of lane width in the AASHTO Green Book (2) for urban areas also reflects a high degree of flexibility. It is noted that lane widths may vary from 10 to 12 ft (3.0 to 3.6 m) for arterials..
