धुलिखेल सिन्धुली बर्दिबास सडक आयोजना

The construction of Banepa Sindhuli Bardibas Road started in November 1996 with a grant assistance of Government of Japan. The main objective of this road is to connect Capital city of Kathmandu with the Eastern Terai and hence linking to neighboring cities in India. This road link is not only expected to provide an alternate link to Kathmandu with the Terai, it is also expected to bring considerable socio- economic changes along its corridor. This road joins Dhulikhel along the Arniko highway to Bardibas along the East West Highway with a length of about 158 km. For the construction purpose this road has been divided into four sections.

• Section I Bardibas- Sindhulibazar section (37 Km)
• Section II Sindhulibazar- Khurkot section (39 Km)
• Section III Khurkot - Nepalthok section (32 Km)
• Section IV Nepalthok-Dhulikhel section (50 Km)

Out of these sections, construction of Bardibas - Sindhuli Bazar section started in November 1996 and was completed in March 1998. The construction of this section included 9 numbers of bridges and 17 numbers of causeways over the 37 km of road, which was constructed in 1987. This section has been opened to traffic since its completion in 1998.

The construction of Nepalthok-Dhulikhel section started in April 1998 and is under construction. This section includes construction of 50 km of road with 5 numbers of bridges and 6 numbers of causeways. Out of 50 km 34 km section of this road has already been completed and is already opened to public traffic while rest of the road is expected to be complete by March 2003.

The construction of Sindhulibazar-Khurkot section started in January 2001, this section includes construction of 39 km of road with a bridge and 3 numbers of causeways. Earthwork over 12.5 km of this road section has been completed. This section is expected to be complete by 2007.

The construction of Khurkot - Nepalthok section has not yet been started and expected to be start soon.

Environmental Issues

After the promulgation of Environmental Protection Act (EPA) for the first time during the basic design of section II Sindhulibazar Khurkot section, a Complete Environmental Impact Assessment was conducted. Extensive discussion on various aspects on environmental issues was discussed with the local people and their concerns are properly addressed. Furthermore, various slope stabilization techniques has been adopted, this includes use of retaining and breast walls, crib works, gabion works, geotextiles and most interesting being the bio-engineering works which includes the locally available techniques like plantation of trees, shrubs including turfing and the soil seeding method imported from Japan. Though initially this technique has been found little expensive because most of the materials used in this method being imported from Japan and for making this method economical effort has been made to use the locally available materials so that this method could be extensively used in Nepal.

Other Issues

In order to effectively address the most common local issues related to local drinking water supply and irrigation channels to the local fields. This project has taken this challenge to properly relocate the existing drinking water supply line and the irrigation channels so that the affect from these could be minimized. Extensive discussion with the locals regarding the environmental issues has been very useful for the project, however the late realization and awareness in these issues is still a challenge to the project to address issues to be faced in later stages of the project execution.

The project for the construction of Sindhuli Road with its total length of 160km, connects Dhulikhel on the Arniko Highway where 31km eastward from Kathmandu city the capital of the country to Bardibas on the East-West Highway crossing the Terai Plain and the way to the border of India is recognized as one of the most important routes of the SRN.

The construction of Sindhuli Road was carried out under the grant assistance of the Government of Japan (GOJ) from November 1996 to 2015. The entire road has been divided into four (4) sections, i.e., Section I: Bardibas-Sindhuli Bazar (L=37km), Section II: Sindhuli Bazar- Khurkot (L=36km), Section III: Khurkot-Nepalthok (L=37km) and Section IV: Nepalthok-Dhulikhel (L=50km).

 

Section I : Bardibas - Sidhuli Bazar (37km)

Section I was constructed to gravel road by GON with the equipment and cash assistance of Government of Japan(GOJ) in 1982. Detailed  Design  was  started  in  August 1995.During November, 1996 – February, 1998   comprising of the construction of nine (9) bridges and seventeen (17) causeways with their associated approach roads have been constructed with grant aid of GOJ, were completed in March 1998.This section was already upgraded to Black top road by DOR.

 

Section II : Sidhuli Bazar - Khurkot (Bara) (36km)

First 6km from Sindhuli Bazar (Elev.; 500m) of this Section II follows the terrace and bank of Gwang River and it ascends for about 800m till it reaches Sindhuli Gadhi (Elev.;1350m) located in Mahabharat Range and descends towards Khurkot.Construction of this road was started in Dec. 2012 and completed in Jan. 2015.

 

Section III : Khurkot - Nepalthok (37km)

This section follows right bank of Sunkoshi River, a principal tributary of Sapta Koshi River. Temporary track road for light vehicles of this section has been completed in February 2009.This section consist of the construction of road with total length of 37km is located in Sindhuli district was completed in 2015.

 

Section VI : Nepalthok - Dhulikhel (50km)

Section VI  connects  Nepalthok  with  Dhulikel  in  Araniko Highway (H03). The  road  passes  through  the  ridge  upto Bhakundebesi (22km) and it follows the bank of Dapcha  River, fore  next  5km. The  road  then  follows  the bank of Roshi River, for rest 23km, comprising five (5) bridges  and  eight  causeways.The construction of this section was started in 1998 and completed in 2003.

 

 

 

OUTLINE OF THE DESIGN

CONCEPT OF DESIGN AND CONSTRUCTION

Sindhuli Road project was carried out with the following main concepts;

1) To maintain an all weathered national highway by ensuring smooth and safe traffic operation

2) To minimize road structures and maximize utilization of locally available material so that construction cost can be minimized as Japanese Grant Aid project

3) To construct sustainable road by applying adequate slope protection and drainage so that maintenance cost is minimized in consideration to the financial situation of Nepal

4) To minimize the impact to natural and social environment and to contribute the local community through increased employment opportunity

5) To transfer the technology concerning the disaster prevention (BOSAI) of road through the construction

Sindhuli Road was planned by realistic concept of the road planning taking into consideration of the limited budget and the objectives of the project.

Therefore, a concept of “Environmental Friendly construction” was introduced the road planning for the project. This concept will be realized for the plan of design speed, road width, alignment plan, bridge and road structures as follow- ings,

1) Application of rather raw design speed of 20 to 40 km/hr, and 1.5 traffic lanes of the minimum 4.75 meters width road as exceptional case in order to avoid the big scale of earthworks and long slope treatment.

2) In depth study of the project route not to pass or affect the potential hazard are with full utilization of prepared “Hazard Map”, and the application of appropriate slope protection or countermeasures against the possible road disaster.

3) Causeway structures are adopted at crossing points of rivers to minimize the budget adjustment for the maintenability and extensibility for the future traffic demand.

4) On the structure design, not only to minimize the construction cost but also raise the future maintenability to use  local materials/products and contribute the local community through increased employment.

Running distance of traffic from Kathmandu to Terai Plain area blocked by Mahabharat Range is reduced by about 150 km after whole of the Sindhuli Road is constructed. Roundtrip of Kathmandu and Central Terai area that requires two days trip is able to be done in one day.

 Past Rout through Narayn Muglin road :               340 km, 9.0 hrs.

 Sindhuli Road Rout:     190 km, 5.0 hrs.

Reduced Distance:    150 km, Reduced Time: 4.0 hrs.
