The highway widening design consists of a four-lane, divided arterial roadway requiring
approximately 32 metres right of way (ROW) in Cumberland Village to as much as 47
metres ROW elsewhere. The existing ROW varies from 30 to 45 metres. To
accommodate this design, property acquisition by way of generally frontage will be
required. General key design elements are noted below and a typical rural
cross-section is illustrated in Figure 1.
In each direction, 3.5-metre lane on the right and 3.75-metre median lane with a
1.2-metre buffer (0.6-metre buffer in Cumberland Village) between the lanes to
protect for an HOV lane.
1.5 to 5-metre wide medians including provisions for left turn lanes at
intersections. Median barriers in rural areas will enhance safety and raised
medians at intersections will improve sight distance.
Signalization at intersections to facilitate turning movements, including u-turns.
2.5-metre enhanced paved shoulders with rumble strips for pedestrians and
cyclists.
Limited multi-use pathways in specific areas along the road corridor.
Curbs and underground storm drain system within the urban area, ditches in the
rural area.
Two new service roads to consolidate driveways and local roads.
Continuous pedestrian and cycling pathway network (on and off-road) from Trim
Road to Canaan Road.
Posted speeds varying from 60 (Cumberland Village) to 80 kilometres per hour.
