CHAPTER 7. IMPROVEMENT PROPOSALS
7.1
INTRODUCTION
Formulation of improvement Proposals is a pre-requisite for development of any project facility.
Highway Improvement options ought to be technically sound, environmental friendly, and
economically most feasible. They not only include formulation of typical cross sections separately
for rural and urban areas depending on requirements of capacity augmentation, but also include:

Provision of rural service roads to interconnect two near by cross roads;

Identification of urban areas that require Bypasses/Re-alignments;

Identification of optimal bridge alignments;

Provision of pedestrian/vehicular underpasses

Provision of bus bays and bus shelters

Provision of way side amenities

Provision of toll plaza
The first step that is required to identify improvement options is to collect information on the
project corridor primarily from engineering surveys and secondarily from various agencies
concerned. Information on past and present traffic, availability of land, condition of CD structures,
potential sources of construction material, environmentally sensitive areas and social hot spots
has been collected from secondary sources. Information pertaining to existing urban settlements,
present configuration of intersections, importance of cross road, utility lines, locations of bus
stops, truck parking has also been collected from primary surveys. Close observation of all these
parameters coupled with frequent site visits lead to identification and finalization of improvement
options for the project corridor.
The project corridor predominantly traverses through rural areas with intermittent settlements at
close intervals. These settlements generally have an intersection coupled with residential and
commercial developments along the corridor. The rural sections of project corridor do not pose
any major concern except for acquiring additional land to make a total land width of 60m as
ROW, which may call for acquisition of some structures along the corridor in rural areas.
The choice available for widening in rural areas are i) Symmetrical widening and ii) Widening
eccentrically. The decision of eccentric widening on either side of the existing road is dependent
upon which side merits preference and the distance of the existing centerline from the RoW
boundaries. The factors influencing the preference are:

Availability of land

Geometric improvement

Utility Lines

Ribbon developments and settlements

Environmental and Social concerns
It is preferred to widen the corridor eccentrically wherever site conditions permit to utilize the
existing formation completely and to avoid two longitudinal joints on either side. Also this would

ensure uninterrupted traffic movement during construction. It is proposed to provide pedestrian
underpasses at locations of schools and rural settlements along the project corridor to avoid
pedestrians entering main carriageway.
Accordingly, the widening options considered for rural sections are

Eccentric Widening on left hand side

Eccentric widening on right hand side
At certain location along, where the developments are on both sides of the project corridor such
as at Banduri (Existing Km 95.0 to 96.0) and at Gadu (Existing Km 101.5 to 102.8), concentric
widening has been resorted to avoid destruction of properties along the road side.
There are few major urban areas along the corridor, namely Nawagadh, Jetpur, Junagadh and
Kesod. Apart from these, there are several other minor settlements and villages along the
corridor where it has been observed that there is sufficient commercial activity and movement of
pedestrians within the settlements. In order to segregate the through traffic from local traffic and
to provide safe passage to slow moving non-motorized vehicles, it is proposed to plan bypass or
realignments for above urban settlements.
At sharp curve locations realignments have been proposed in order to meet the design speed
criteria.
7.2
BYPASS CANDIDATES
Nawagadh and Jetpur are twin settlements at the beginning of the project corridor which are
connected with each other and have continuous developments on either side of the road
Presently all the traffic is moving through these developments is experiencing severe
congestion. Apart from these developments there are two railway crossings, one is a Road under
Bridge (RUB), with insufficient clearance and the other one is at grade level crossing. Hence it is
required to bypass initial developments of Jetpur-Nawagadh.
Junagadh is Major urban settlement along the corridor, which is presently having a two lane
bypass for about 10km length. Part of this bypass is yet to be constructed on Jetpur side as it
requires a ROB. Presently, an existing state highway is used for this missing link which has one
at grade railway crossing. There are very little developments adjacent to this existing bypass for
substantial length except for end section on Somnath side of Junagadh, continuous
developments have been observed along the bypass and beyond the existing bypass for a length
more than 1 Km. Further to this, Project corridor has an at-grade junction at the end where the it
takes a perpendicular right turn towards Somnath. There is one at-grade railway crossing near
the end of bypass. Beyond, the bypass, the existing road again crosses the same railway line
with a two lane ROB. Hence, there would be a requirement of extending/connecting exiting
bypass at both ends for Junagadh town.
Kesod is another major urban settlement along the corridor, which is presently having a four lane
divided road for some length. The project corridor mostly traverses through continuous

MAIN REPORT
settlements in the Kesod town with substantial local traffic movement. There is a bypass
proposal that has been already made for this town on right hand side of the town while moving
towards Somnath by the R & BD,-NH division and a land width of 30m has already been
acquired for the same.
In addition to these three major settlements, two minor settlements at Vanthali (Km 46.5) and
Agatrai (Km 61) along the corridor require realignments.
The above settlements require bypasses/realignments because of continuous and thick ribbon
developments, non-availability of Right of Way and poor geometry. There are proper buildings
very close to the existing carriageway at these locations. It would not be possible to
accommodate four lane cross section with service roads through these urban areas within the
available ROW. Acquisition of land through these settlements appears to be difficult due to social
resistance. Initial appreciation of these urban areas revealed that there is enough space to take
bypasses on either side of towns. Details of these realignments are given below in the table.
Elaborate description of bypass alignments is presented in the next chapter in this volume of the
report.

GRADE SEPARATORS/ UNDERPASSES
It is proposed to provide flyovers/vehicular underpasses at some locations of major intersections
and urban areas in order to provide an uninterrupted flow for through traffic moving on the project
corridor. These flyovers/underpasses were proposed to have 2-lane configuration in each
direction with service roads at ground level for movement of local traffic.
In addition to above, it is also proposed to provide vehicular underpasses in newly proposed
bypass alignments where alignment crosses a major road and cattle passes in rural sections
where agricultural lands and village are separated by project corridor.
Details of these grade separators/underpasses are mentioned below in the following sub
sections:

SERVICE ROADS
Service roads of adequate width have been proposed between two close-by intersections or
settlements to enforce proper access control along the corridor. Service roads in the form of slip
roads have been also proposed at all VUP and Flyover locations and at few PUP locations.
These details have been provided in chapter 9 of this volume.

TYPICAL CROSS SECTIONS
Cross sectional elements are based on the design standards and specifications set in the earlier
chapters. The lane width shall be 3.5m, paved shoulder width 1.5m, hard shoulder width 1.5m,
median width 4.5m/1.5m and shyness strip 0.25m on both sides of median. While lane width for
service roads and slip roads is 5.5m/7.0m.
Based on foregoing considerations various typical cross sections have been developed for the
project corridor to suit the specific site requirement. The following table presents the summary of
cross section schedule while the details are elaborated in the Chapter 9: Preliminary Designs of
this report.

Vehicular Underpasses
For cross movement of traffic, underpasses are proposed at regular intervals along the project
corridor. The Manual of Specifications for four laning of NHs obviously recommends the provision
of vehicular underpasses along the highway. The vehicular underpasses are of 5m vertical
height. Keeping this in mind, the Consultants have proposed underpasses at the locations as
listed in the Table 7-8 below.

Pedestrian Underpasses
As the project is proposed to develop as an access controlled highway and direct access of local
traffic to main highway is not deemed to be provided. However, to facilitate the movement of
pedestrians only from one side of project road to other side, underpasses are essential. The
Manual of Specifications for four laning of NHs obviously recommends the provision of
pedestrian underpasses along the highway. The Consultants have proposed underpasses at the
locations with sizes of structures as listed in the Table 7-9 below.
