1. TYPES OF ROADS FUNDED BY KIIFB
KIIFB shall undertake the funding of two main types of road/highway projects viz., new
formation and upgradation of road/highway projects which include improvement/strengthening
and/or widening works.
Among the afore mentioned types of road/highway projects, the funding shall be restricted to
the following categories of road/highway projects
 State Highways
 Bypass (to NH / SH / MDRs) / Ring road Projects
 Hill Highway
 Coastal Highway
 Other KIIFB Roads
 City Roads (Arterial Roads)
2. STAGES IN PROJECT PREPARATION
The stages involved in the preparation and sanction of road projects are:
a) Pre-feasibility study
The pre-feasibility study is necessary to enable the funding agency to appreciate
the features of the project. This is to be done based on reconnaissance survey by collecting
