6.8 Operation and Management
6.8.1 Utility Services
6.8.1.1 Expressways should not be used for the location of utility services which are not related to
the operation of the Expressway, except of course for services which are essential to the
operation of the Expressway such as power cables for the road lighting, and telephone lines
for the emergency telephones as well as power and communication cables for traffic
surveillance and control facilities.
6.8.1.2 In the event that a non-operational utility service is required to be placed along or across an
Expressway consent in writing with justification to allow this must be obtained from the
Regional Chief Highway Engineer of Highways Department. Approval should not be
given unless:
(i)
(ii)
(iii)
it is in the interest of the public for the proposed services to be installed;
the installation works would not involve any open cut excavation works within the
carriageway or the hard shoulder nor would require any access from the Expressway;
the underground services are installed in such a way that it will not be necessary to
excavate any part of the carriageway and hard shoulder for future inspection,
maintenance or replacement.
6.8.1.3 Additionally such utility services should only be permitted to be laid along adjacent verge.
In the situation that non-operational utility services need to be laid across an Expressway
beneath the carriageway, their provision should be such that for any future inspection,
maintenance or replacement it will not be necessary to excavate any part of the carriageway
and preferably any part of the hard shoulder, nor should manholes for these service be
permitted in the carriageway and, if possible, not in the hard shoulder either.
6.8.1.4 Where there are existing non-operational services in an Expressway, consideration should be
given to their removal or relocation when repairs or alterations are being entertained.
6.8.1.5 Any illegal services encountered within the boundary of the Expressway should be removed
as quickly as possible. Such illegal services will generally be a safety hazard and very
often produce highway maintenance problems due to their presence.
