Improvement & upgradation of Bilikere – Belur road SH : 57
 
1.1   Background :

Existing Bilikere to Belur via K.R. Nagar, Holenarasipura, Hassan is an intermediate lane (5.5m) State Highway of  127.0 Km  length. This State Highway takes off from Mysore – Bantwal road (SH : 88) approx. @ Km 29.90. The  road  passes  through plain and rolling terrain with number of horizontal curves and connects two important tourist centres  viz. Mysore and Belur.

The  road  crosses  three  major rivers viz. Lakshmana Thirtha, Cauvery and Hemavathy at     Kms 3.90, 18.2 & 58.6  respectively. There  are  251  cross  drainage  structures  along  this State Highway including three major bridges across above rivers with narrow carriageway width.

The  road  is  generally  on  an  embankment  of  varying height and in few locations it is in cutting. The wearing course  is  of  premix  carpet  of varying thickness and not been resurfaced for quite sometime. The condition of existing pavement is fair to poor except a stretch from Km 84 to Km 92, which is in good condition.

The traffic on the road is mixed. Passenger traffic is more than commercial vehicles. Significant volume of traffic gets diverted at Km 92 towards Belur from NH-48.


1.2  Proposed improvement works : To Top

· Improvement to curves

 

Existing road  has  number  of  horizontal and vertical curves. These  do  not  satisfy  the requirement of standards and also cause  for  number  of  accidents  along  the  road  as well as delay  in  journey period. Therefore, geometric corrections of   the  existing  horizontal  curves,  vertical  curves   and   super elevation  will  be  carried  out  to  a  design   speed   of   80   kmph   in accordance with Indian Roads Congress standards.

· Capacity of road 

Traffic  movement  along  the  road  keeps  increasing  every  year. To  take  care  of  the   future   increase  in traffic ,  existing  carriageway  width  of  5.5m  will  be  widened  to  7.0m  with  or  without  paved  shoulder to accommodate  the  projected  traffic  volume  after  20  years .  The  roadway  width  as  far as possible will be maintained 12.0m throughout.

· Existing pavement and improvement

The  existing  pavement  has  cracks, pot holes, ravelling
and  edge  breaking. This  will  lead  to poor riding quality
surface   for   the   commuters   in    addition    to    more consumption  of  fuel ,  wear  and  tear   of   the   vehicle. Therefore, longitudinal and cross profile corrections of the road  will  be  suggested as per the design.The pavement structure  on  the proposed widening and shoulder portion will   be   constructed   as   that   of   main   carriageway. Geosysthetics    and    polymer   modified   bitumen   are considered  as  new  materials  of   construction   in   the pavement.    The    design     of     pavement     thickness (strengthening)    will   be   carried   out   based   on   the geotechnical    investigations    of    subgrade    soil   and deflection  survey  on  existing  pavement. This  will  take care  of  the  increase  in  (axle)  load  carried  by   heavy commercial vehicles in future.
·   Drainage

One  of the reasons for road pavement failure is
improper  drainage   for  rain  water. Good  road
drainage    increases    the   life   of   pavement
considerably. Therefore, necessary  pucca  and
kutcha  drains,  whichever  is  relevant   will   be
proposed  for   construction   along   the   State
Highway  to  drain  off  the  surface  rain   water.
Earthen  shoulders and verges will be graded to required slope towards drain.
·  Major / Minor bridges and structures
To  avoid  overflow  of  water  on  road  during floods, vent ways  are  to be maintained properly. The materials used would  have  been  either  worn  out, cracked, eroded etc. This will call for maintenance of structures and protection
of    approach   embankments   on   either   side   of   the structures.
 All structures all along the road will be visually inspected
for  their  present   condition .  Repairs  /   rehabilitation  / reconstruction will be proposed depending on the present condition  of  distress .  Hydraulic  adequacy of vents will also  be reviewed after ascertaining the flood discharge at structures. Narrow  carriageway  of  major / minor bridges and  culverts  will  be  widened  to  7.0m  and roadway at structure locations will be maintained as 12.0m.
·Road furniture
Road furniture will be improved to the requirement of IRC standards. Retroreflective signages and thermoplastic pavement markings will be proposed for construction. These will improve the visibility of road better during night commuting  and  accidents  could  be  reduced .  Crash  barrier  will  also  be  proposed  for   construction   on embankment height more than 3.0m high to avoid vehicles going down the embankment.
·Road facilities
Facilities  viz . bus  bays and lay byes will be proposed at appropriate locations for the convenience of the road user. Bus  bays / bus  stop  will  be useful for the villagers who keep using buses, maxi cabs as means of their transport  and to avoid inconvenience to the fast moving traffic. Lay byes are considered to provide facilities viz. fuel, catering, telephone etc.
·Tree cutting
As  number  of  horizontal  curves  are  to  be
 improved  and  road  to  be  widened to 7.0m
 carriageway  width  it  becomes  unavoidable 
to  cut  few  trees   all   along   the   road.  To 
compensate  this, it  will be proposed to plant 
two samplings  for  every  tree felled. However,
tree cutting will be minimized as far as possible.

1.3 Investigations and Surveys: To Top

Following  surveys ,  investigations  and  analysis  is  being  carried  for  improvement  of  the existing road and structures :

·         Topographic survey
·         Traffic survey
·         Road inventory and condition survey
·         Bridge / structure inventory and condition survey
·         Hydrology and drainage investigations
·         Soil investigations
·    Material investigations


1.4 Economic Evaluation : To Top

Economic  evaluation  is  also  being  carried  out  to understand the economic viability of the project for twenty years following the completion of the rehabilitation of the project road.


1.6 Present Status: To Top

The work of strenthening and widening of Bilekere-Belur Road-Package-II(40 to 84 Km)is taken up during June 2002 and expected to be completed by June 2004.The work is entrusted to M/s.DEsert Line Projects-Bhoorathnam & Co(J.V) at a cost of Rs.28.50 Crores.
