6.2 Introduction
6.2.1 General
6.2.1.1 Expressways, which will be designated as such under Expressways Legislation, are roads
connecting the main centres of population within the Territory. They must be to dual
carriageway standard with appropriate alignment, and widely spaced grade separated
junctions. No frontage access will be allowed and the provision of intermediate grade
separated junctions to allow for specific developments should not be permitted.
Pedestrians, cyclists, learner drivers, hand carts and animals will be prohibited and all
pedestrian cross movements must be fully segregated. The stopping of vehicles, other than
in an emergency or similar, will generally be prohibited and therefore lay bys, or other off
road stopping facilities, should not be provided, except for appropriately spaced police
observation platforms and purpose designed service areas. A hard shoulder should be
provided adjacent to the slow lane of each carriageway throughout the length of the
Expressway. The hard shoulder must be of the same construction as the adjacent
carriageway so that it can be utilised as a traffic lane in emergencies or for maintenance
purposes.
6.2.1.2 In the hierarchy of road types referred to Chapter 3 of this Volume, an Expressway may be
formed from a trunk road.
6.2.1.3 At each grade separated junction the roads connecting the Expressway with the minor road
system are referred to as 'slip roads'.
6.2.1.4 Roads connecting one Expressway with another Expressway are 'link roads' and must be
designed to full Expressway standards.
6.2.1.5 An overbridge is a bridge that spans across an Expressway.
6.2.1.6 The near side lane of each carriageway adjacent to the hard shoulder is the 'slow lane' whilst
the off side lane of each carriageway next to the central reserve, is the 'fast lane'. On
carriageways having three or more lanes, the intermediate lanes will be referred to as the
'middle lane or lanes'
6.2.1.7 Roads are designated as Expressways only if they meet the required Expressway standards.
Roads should not be incorporated into the Expressway system as isolated sections.
Therefore until at least a major part of it can be designated as an Expressway, such sections
should not be included as part of the network. In this respect a major part should be
regarded as, at least, that section of a route connecting two major areas of population.
6.2.1.8 Route numbering for Expressways must follow the Territory route numbering system as
detailed in Chapter 3 of Volume 3 of this Manual.
6.2.1.9 The provision of bus lanes, exclusively for the use of franchised buses, is not generally
appropriate for Expressways, as these will interfere with weaving movements at junctions
and complicate enforcement in respect of excluding medium and heavy goods vehicles from
the fast or outer lane of a three lane dual carriageway. However, in the event that the
movement of public transport is impeded on an Expressway, an exclusive bus lane is still
considered desirable if no alternative solution can be worked out.
